Elucidating Fundamental Mechanisms of Gut-Brain Signaling in C. elegans

Little is understood about how the gut and brain interact mechanistically. Dr. Flavell’s research will build on discoveries his lab has made studying the C. elegans worm, whose simple and well-defined nervous system can generate relatively complex behaviors that are easily studied in the lab. Dr. Flavell and his team have identified a specific type of enteric neuron (neurons lining the gut) that is only active while C. elegans feed on bacteria. His experiments will identify the bacterial signals that activate the neurons, examine the roles of other neurons in gut-brain signaling, and examine how feedback from the brain influences the detection of gut bacteria. This research could open new lines of inquiry into the human microbiome and how it influences human health and disease, including neurological and psychiatric disorders.

Nuo Li, Ph.D., Assistant Professor of Neuroscience, Baylor College of Medicine, Houston, TX

Cerebellar Computations during Motor Planning

Dr. Li’s lab has revealed that the anterior lateral motor cortex (ALM, a specific part of the mouse frontal cortex) and the cerebellum are locked in a loop while the mouse is planning an action. Still unknown is exactly what information is being passed back and forth, but it is distinct from the signal that actually drives the muscles. If the connection is disrupted even for an instant during planning, the movement will be made incorrectly.

Dr. Li’s experiments will uncover the role of the cerebellum in motor planning and define the anatomical structures that link it and the ALM. He will map the cerebellar cortex and find out which populations of a special type of cell used in cerebellar computation, called Purkinje cells, are activated by the ALM in motor planning, and what signals they send back and forth while planning. A second aim will explore what kind of computation the cerebellum is engaged in. Through this work, Dr. Li will learn more about these sophisticated, fundamental brain processes.

Lauren O’Connell, Ph.D., Assistant Professor of Biology, Stanford University, Stanford, CA

Neuronal Basis of Parental Engrams in the Infant Brain

Dr. O’Connell’s work will help identify how memories are formed in infancy as part of the bonding process, will trace those memory imprints to identify how they affect future decision-making, and will explore the neurological impact of disrupted bonding. In the frogs O’Connell is studying, receiving food and care leads the tadpole to imprint on the parent, which in turn affects the tadpole’s future choice of mate: it will prefer mates that look like the caregiver.

O’Connell has identified neuronal markers that are enriched in tadpoles that beg for food which are analogous to those implicated in a range of neurological issues related to learning and social behavior in humans. Her research will explore the neuronal architecture involved in infant recognition and bonding with caregivers, as well as brain activity when making mate choices later in life, to see how neuronal activity in each process is related.

Zhaozhou Qiu, Ph.D., Assistant Professor of Physiology and Neuroscience, Johns Hopkins University, Baltimore, MD

Discovering Molecular Identity and Function of Novel Chloride Channels in the Nervous System

Much research to date has been focused on ion channels conducting positively-charged ions, such as sodium, potassium and calcium. However, the function of ion channels allowing the passing of chloride, the most abundant negatively-charged ion, remains poorly understood. By performing high-throughput genomics screens, Dr. Qiu and his research team have identified two new families of chloride channels, activated by cell volume increase and acidic pH, respectively. His research aims to investigate the neurological function of these new ion channels with a focus on neuron-glia interactions, synaptic plasticity, and learning and memory. Dr. Qiu will extend this approach to other mysterious chloride channels in the brain. His research will provide key insights into how chloride is regulated in the nervous system.

Maria Antonietta Tosches, Ph.D., Assistant Professor, Columbia University, New York, NY

The Evolution of Gene Modules and Circuit Motifs for Cortical Inhibition

Modern brains were shaped by a long evolutionary history. Dr. Tosches is conducting research to understand these processes and figure out what fundamental neural systems have been conserved in vertebrate animals separated by hundreds of millions of years of evolution.

Dr. Tosches is exploring the evolutionary history of GABAergic neurons. Her previous experiments have found the GABAergic neurons of reptiles and mammals are genetically similar, indicating that these neuron types existed already in vertebrate ancestors; they also share gene modules associated with specific neuronal functions in both types of brains. In Tosches’ new research, she will determine if these same neurons types are found in the simple brain of salamanders. This work will introduce a completely new animal model to circuit neuroscience, adding to our understanding of how the brain works at a fundamental level.

Daniel Wacker, Ph.D., Assistant Professor, Icahn School of Medicine at Mount Sinai, New York, NY

Accelerating Drug Discovery for Cognitive Disorders through Structural Studies of a Serotonin Receptor

Dr. Wacker proposes a novel approach to drug discovery that focuses in on a specific serotonin receptor known as 5-HT₇R (which doesn’t carry the same risks as activating the dopamine system as many drugs do), carefully mapping that receptor’s structure at a molecular scale, and seeking out compounds that will bind to that receptor in a specific way. Dr. Wacker proposes to conduct a structural study of the receptor using X-ray crystallography on purified samples of the receptor. Wacker’s team will then conduct a computerized search of hundreds of millions of compounds, comparing their 3D structure with the 3D model of the receptor for those most likely to “fit.” This computerized process offers the opportunity to essentially pre-screen drugs based on their structure, and speed their development.

Jayeeta Basu, Ph.D., Assistant Professor, Neuroscience Institute, New York University School of Medicine, New York, NY

Cortical Sensory Modulation of Hippocampal Activity and Spatial Representation

Dr. Basu aims to map the circuitry involved between the LEC and specific hippocampal neurons. Her lab will directly record the signals received by the thin dendrites of the neurons when LEC signals are sent with or without MEC signals, and at different signal strengths. A second series of experiments with mice will test the hypothesis that these LEC inputs support the creation of memories of place while learning – scent cues will trigger behavior to seek rewards at distinct places. Researchers will see how switching on or off LEC signals during learning or during recall affect the activation of place cells in the brain and the learning behavior itself. This research may be relevant in future studies of Alzheimer’s disease, PTSD and other conditions where memory and contextual “triggers” are activated.

Juan Du, Ph.D., Assistant Professor, Structural Biology Program, Center for Cancer and Cell Biology, Van Andel Research Institute, Grand Rapids, MI

Regulation mechanism of thermosensitive receptors in nervous system

Dr. Du will conduct a three-part project to unlock the secrets of how temperature information is received and processed by the neural system. She is looking at three particular receptors, one that detects cool and cold temperatures externally, one that detects extreme external heat, and one that detects warm temperatures in the brain (for regulating body temperature.) She will first identify purification conditions for these receptors so they can be extracted and used in lab experiments and still operate the same as receptors in the body.

A second aim is to see what structures on the receptors are activated by temperature and understanding how they work. This will also include the development of new therapeutics that can bind to these structures and regulate them. Third, when the structures are understood, validation experiments in which the receptors are mutated to change or remove temperature sensitivity will be conducted, first on cells, and then in mice, to see how alterations to temperature-sensitive receptors impact behavior.

Mark Harnett, Ph.D., Assistant Professor, Brain and Cognitive Sciences, Massachusetts Institute of Technology, Cambridge, MA

Perturbing Dendritic Compartmentalization to Evaluate Single Neuron Cortical Computations

Dr. Harnett is looking at dendrites in the visual system with precise electrical and optical tools, to measure how signals travel down dendrite branches, and measure how altering the dendrites changes how the neuron operates. These perturbations will allow Dr. Harnett to test if inhibiting signals on a specific branch of a dendrite changes how the neural network responds to certain visual stimuli. Learning that a single neuron is essentially made up of its own network of smaller signal processors would change our understanding of how the brain computes. Among other things, this could affect how artificial intelligence, which is modelled on neural networks, evolves in years to come.

Weizhe Hong, Ph.D., Assistant Professor, Departments of Biological Chemistry and Neurobiology, University of California, Los Angeles, CA

Neural Circuit Mechanisms of Maternal Behavior

A particular focus of Dr. Hong’s work will be investigating the role of an evolutionarily conserved brain region called the amygdala in controlling parenting behavior. While female mice usually engage in extensive pup nurturing behaviors, male mice generally do not show parenting behavior until their own offspring are born.

The research will identify specific, molecularly defined neuronal populations that mediate parenting behavior. The research will also compare the neural circuits in males and females to understand how neural activity in these neurons regulates parenting behavior. This research will provide key insights into the neural basis of an essential social behavior and the basic principles governing sexually dimorphic behaviors.

Rachel Roberts-Galbraith, Ph.D., Assistant Professor, Department of Cellular Biology, University of Georgia, Athens, GA

Regeneration of the Central Nervous System in Planarians

By studying successful neural regeneration in the natural world, Dr. Roberts-Galbraith hopes to learn details about the mechanism of neural regeneration and the role of different cells. One aim is to investigate whether neurons can detect injury and self-initiate repairs themselves by sending signals that trigger and direct regrowth. Dr. Roberts-Galbraith hypothesizes that neurons influence planarian stem cells, which are recruited to regrow parts of the central nervous system (and other body parts). Fine control of stem cells is critical for regeneration, as planarians faithfully replace missing tissues and never develop tumors.

Another aim is to examine the role of glial cells, which have traditionally been seen as the glue of the nervous system but which clearly possess more significant roles than previously recognized. Glial cells make up a large part of animals’ nervous systems and must be regenerated along with neurons; they are also likely to modulate neuronal regeneration. The hope is this research will provide more understanding of how regeneration can happen in the most successful cases, and perhaps inform new ways of thinking about neural regeneration in humans.

Shigeki Watanabe, Ph.D., Assistant Professor of Cell Biology and Neuroscience, Johns Hopkins University, Baltimore, MD

Mechanistic Insights into Membrane Remodeling at Synapses

Dr. Watanabe will use a technique called flash-and-freeze electron microscopy to research this process. Neurons will be stimulated with light – the flash – then the process will be stopped precisely with high-pressure freezing at precise time intervals microseconds after stimulation. The frozen synapses can then be visualized with an electron microscope. By taking a series of images frozen at different time intervals after stimulation, Dr. Watanabe will create a step-by-step visualization of the process and identify the proteins involved and what they do. Not only will this give a better understanding of how neurons work, it has implications for diseases that are related to faulty neural transmission, such as Alzheimer’s Disease.

Eiman Azim, Ph.D., Assistant Professor, Molecular Neurobiology Laboratory,

Salk Institute for Biological Studies, La Jolla, CA

Spinal Circuits Controlling Dexterous Forelimb Movement

Dexterous movements of our arms, hands and fingers are fundamental to our everyday interactions with the world, but science is just starting to scratch the surface of understanding how specific neural circuits control the precision, speed and fidelity of these impressive motor behaviors. Dr. Azim’s laboratory at the Salk Institute is at the forefront of this field, deploying a multidisciplinary approach aimed at dissecting the molecular, anatomical and functional diversity of motor pathways one element at a time. Taking advantage of recent advances in machine learning, computer vision technology and molecular-genetic tools, the Azim Lab aims to develop more standardized, unbiased, high-throughput approaches to piecing together the neural underpinnings of movement–especially skilled motions like goal-directed reaching and grasping. His findings could help to clarify how disease or injury disrupts the normal execution of movement, paving the way for improved diagnosis and treatment.

Rudy Behnia, Ph.D., Assistant Professor of Neuroscience, Columbia University-Zuckerman Mind Brain Behavior Institute, New York, NY

State-dependent Neuromodulation of a Circuit for Motion Vision

Dr. Behnia studies the dynamic processes devoted to vision, exploring how the brain’s visual system drives behaviors and helps animals and humans survive and thrive in complex environments teeming with sensory stimuli. Using the fruit fly model system, Behnia’s laboratory investigates how animals perceive and adapt their behavior to changing environments through a variety of complementary techniques, including in vivo single cell patch-clamp recordings, two-photon activity-imaging, optogenetic and behavioral paradigms. A particular focus of Dr. Behnia’s McKnight-funded work will be exploring how internal states such as attention alter the brain’s sensitivity to certain stimuli, research that could shed new light on the role neuromodulators play in changing the function of neural circuits. This research may also reveal new targets for therapeutic strategies for disorders such as depression and ADHD.

Felice Dunn, Ph.D., Assistant Professor of Ophthalmology, University of California, San Francisco

The Establishment and Regulation of Rod and Cone Vision

Dr. Dunn’s research is focused on finding out how visual information is parsed and processed in the retinal circuit, knowledge that could open new avenues for restoring lost vision. While many retinal diseases that lead to vision loss or blindness begin with the degeneration of photoreceptors, how disease progresses to affect postsynaptic neurons is still largely unknown. In her lab, Dunn deploys temporally-controlled transgenic ablation of photoreceptors, functional recordings and imaging of single cells, and gene-editing methods to investigate the retina’s remaining cells and synapses. Her work will help to uncover how the remaining circuit changes its structure and function in a degenerating retina, and may help reveal potential therapies to halt or prevent the loss of vision.

John Tuthill, Ph.D., Assistant Professor, Physiology and Biophysics, University of Washington, Seattle

Proprioceptive Feedback Control of Locomotion in Drosophila

Proprioception–the body’s sense of self-movement and position–is critical, for the effective control of movement, yet little is known about how the brain’s motor circuits integrate this feedback to guide future movements. Dr. Tuthill’s lab is working to unlock the essence of motor learning in the brain by investigating how walking fruit flies learn to avoid obstacles and navigate unpredictable environments, assessing the role of sensory feedback in motor control by optogenetically manipulating proprioceptor activity. A deeper understanding of proprioceptive feedback control has the potential to transform the way in which we understand and treat movement disorders.

Mingshan Xue, Ph.D., Assistant Professor, Baylor College of Medicine, Houston, TX

Function and Mechanism of Input-specific Homeostatic Synaptic Plasticity In Vivo

Navigating complex environments and changing internal states, the healthy brain maintains a constant balance between excitation and inhibition (often characterized as E/I ratio) that’s remarkably stable.  How does the brain maintain this balance? Dr. Xue’s laboratory will explore this question, combining molecular, genetic, electrophysiological, optogenetic, imaging, and anatomical approaches to determine whether homeostatic plasticity regulates synapses in an input-specific manner in vivo, thereby maintaining neuronal activity levels and functional response properties. Gaining a deeper understanding of how the normal brain copes with perturbations can pave the way for interventions to treat neurological diseases that disrupt the brain’s natural balance.

Martha Bagnall, Ph.D., Assistant Professor of Neuroscience, Washington University in St. Louis School of Medicine

Sensory and motor computations underlying postural control 

Posture is crucial to normal function, but little is known about how the brain successfully routes sensory signals about orientation, movement and gravity through the spinal cord to keep the body “right side up.” Dr. Bagnall’s lab studies how animals maintain posture by focusing on the vestibular system of the zebrafish, a model organism with a spinal cord remarkably similar to limbed mammals. In early development, the spinal cords of larval zebrafish are transparent, providing researchers a valuable glimpse at the diverse populations of neurons activated during different types of movements. By learning more about how these distinct premotor pathways are recruited during postural behaviors—allowing animals to adjust to changes in roll and pitch—Bagnall’s research may reveal new discoveries about the complex neural connections that govern equivalent behavior in humans. Her work could also inform the development of devices that can help people regain their balance and posture, and improve the lives of people whose balance has been impaired by injury or disease.

Stephen Brohawn, Ph.D., Assistant Professor of Neurobiology, Helen Wills Neuroscience Institute, University of California, Berkeley

Mechanisms of biological force sensation

Dr. Brohawn studies life’s electrical system from a molecular and biophysical perspective, with a focus on finding the answer to the question “How do we feel?”  The nervous system’s capacity to sense mechanical force is one of the foundations of hearing and balance, but science hasn’t yet revealed the protein machinery that converts mechanical forces into electrical signals. Using a range of approaches from X-ray crystallography to cryo-electron microscopy, Brohawn’s lab takes a “bottom up” approach to the question, capturing atomic resolution snapshots of the membrane proteins when at rest and under force. Gaining an understanding of how hearing and balance work on a detailed molecular level may someday form the basis for new therapies to improve the lives of individuals who’ve experienced auditory or vestibular loss of function.

Mehrdad Jazayeri, Ph.D., Assistant Professor, Massachusetts Institute of Technology/McGovern Institute of Brain Research

Thalamocortical mechanisms of flexible motor timing

Matthew Pecot, Ph.D., Assistant Professor, Harvard Medical School

Defining the transcriptional logic underlying neural network assembly in the Drosophila visual system 

The precision with which neurons form synaptic connections is fundamental to animal behavior, yet how neurons identify correct synaptic partners amidst the staggering cellular complexity of the nervous system is unclear. To identify molecular principles underlying synaptic specificity the Pecot lab studies neural connectivity in the fly visual system, which comprises well-defined genetically accessible neuron types with known patterns of synaptic connectivity. Based on their research, they propose that correct synaptic partners express a common master regulator protein which controls the expression of molecules that instruct their synaptic connectivity. Ensuring that neurons destined to form connections express the same master regulator may provide a simple strategy for establishing precise neural connections. With a growing body of evidence identifying defects in neural connectivity as a driver in neurological disease, Dr. Pecot’s research could inspire therapeutic strategies focused on rewiring damaged neural circuits in affected individuals.

Mark Andermann, Ph.D., Assistant Professor of Medicine, Beth Israel Deaconess Medical Center, Harvard Medical School

A pathway for hunger modulation of learned food cue responses in insular cortex

Dr. Andermann’s research addresses the ways the brain notices and acts upon images relating to food, especially when an individual is hungry. His work is driven by the urgent societal need to develop comprehensive therapies for obesity. Humans pay attention to the things their bodies tell them they need. Over-attention to food cues, which results in seeking more food than is needed, can persist in individuals suffering from obesity or eating disorders, even when satiated. Andermann’s lab developed a method involving two-photon calcium imaging through a periscope to study hundreds of neurons in a mouse brain, and found that the brain’s response to images associated with food differed depending on whether the mouse was hungry or sated. The Andermann lab is collaborating with Dr. Brad Lowell’s lab—experts in the brain circuitry controlling hunger—to study the insular cortex in search of ways to prevent cravings for the wrong foods in obese subjects.

John Cunningham, Ph.D., Assistant Professor, Department of Statistics, Columbia University

The computational structure of populations of neurons in the motor cortex

Dr. Cunningham’s primary research mission is to advance the scientific understanding of the neural basis of complex behaviors. For example, better understanding the brain’s role in generating voluntary movements can potentially help millions of people with motor impairments due to disease and injury. Cunningham is part of a small but growing field of statisticians applying statistical and machine learning techniques to neuroscience research. He combines aspects of mathematics, statistics, and computer science to extract meaningful insights from massive datasets generated in experiments. He aims to bridge the gap between data recording and scientific payoff, seeking to create analytical tools he and other researchers can harness. Analysis methods capable of handling the massive datasets generated are essential to the field, particularly as researchers record evermore data of increasing complexity.

Roozbeh Kiani, M.D., Ph.D., Assistant Professor, New York University, Center for Neural Science

Hierarchical decision processes that operate over distinct time scales underlie choice and changes in strategy

Dr. Kiani is researching how adaptive behavior occurs in decision making. Decisions are guided by available information and strategies that link information to action. Following a bad outcome, two potential sources of error—flawed strategy and poor information—must be distinguished to improve future performance. This process depends on interaction of several cortical and subcortical areas that collectively represent sensory information, retrieve relevant memories, and plan and execute desired actions. Dr. Kiani’s research focuses on the neuronal mechanisms that implement these processes, especially how sources of information are integrated, how relevant information is selected and routed flexibly from one brain area to another, and how the decision-making process gives rise to subjective beliefs about anticipated outcomes. His research could have long-term implications for the study of neurological disorders that disrupt decision-making processes such as schizophrenia, obsessive-compulsive disorder, and Alzheimer’s.

Abigail Person, Ph.D., Assistant Professor of Physiology and Biophysics, University of Colorado Denver

Circuit mechanisms of cerebellar motor correction

Movement is central to all behaviors, yet the brain’s motor control centers are barely understood. Dr. Person’s work explores how the brain makes movements precise. Person’s lab is particularly interested in an ancient part of the brain called the cerebellum, asking how its signals correct ongoing motor commands. The cerebellum has been particularly attractive for circuit analysis because its layers and cell types are very well defined. However, its output structures, called the cerebellar nuclei, violate this rule and are much more heterogeneous and hence, much more confusing. Using a variety of physiological, optogenetic, anatomical and behavioral techniques, her research aims to untangle the mix of signals in the nuclei to interpret how it contributes to motor control. Person anticipates that her research may offer clinicians insight into therapeutic strategies for people with cerebellar disease, and could potentially contribute to the class of technologies that use neural signals to control prosthetic limbs.
