The Banerjee lab studies vocal communication across rodents with a special emphasis on the Alston’s Singing Mouse\u2014a New World rodent native to the cloud forests of Central America. Unlike most rodents that emit only soft, variable, ultrasonic vocalizations, these singing mice also produce loud, stereotyped, human-audible songs used for fast vocal interactions resembling human conversation. Using this model system, the Banerjee lab pursues two complementary questions: How does the auditory system interact with the motor system to generate the fast sensorimotor loop required for vocal interactions? And how do changes in neural circuits enable the rapid evolution of novel vocal behaviors?<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div>

Dr. Yvette Fisher\u2019s research seeks to use navigational circuitry to understand how neural circuits perform different computations under different conditions.

Proprioceptors are the specialized sensory neurons in the peripheral nervous system that initiate proprioceptive signaling and are traditionally known for their ability to shape motor function by encoding muscle length and force. Work in Dr. Theanne Griffth\u2019s lab is aimed at demonstrating that their physiological functions are more complex and far-reaching.<\/p>\n
In her research, Dr. Griffith is uncovering a new role for sensory proprioceptive signaling as a key driver of developmental and adaptive processes within motor systems.

Dr. Lovett-Barron will investigate these mechanisms in glassfish, a small optically-accessible fish that schools using vision. By imaging neural activity across the brains of glassfish engaged in a social virtual reality, the Lovett-Barron lab will identify the neural circuits that enable fish to extract relevant cues from the movements and postures of their neighbors.

Dr. Pinto and his team will probe how information flow through cortical circuits is rerouted on the fly by neuromodulatory molecules to meet cognitive demands. They have leveraged their expertise in computer-automated behavioral training to create a decision-making task for mice navigating in virtual mazes, which disentangles several cognitive processes for the first time. While mice perform this task, Dr. Pinto\u2019s lab will use cutting-edge in vivo<\/em> microscopy tools to measure and perturb the activity of cortical neurons, and of the cortical and neuromodulatory inputs they receive.

It sits at a vertex with other cognitive abilities, including memory and executive control, and underpins both our individual and societal intelligence. Due to the lack of animal models and the rarity of human brain recording, little is known about the biological basis of language at the resolution of circuit computation \u2013 individual neurons.\u00a0\u00a0Moreover, we have no technologies to repair the devastating loss of the ability to communicate through language due to neurological injury.<\/p>\n
Dr. Stavisky and his team hope to address this neuroscientific and medical gap by identifying the neural representations of semantic features across the brain\u2019s language network. They will record from thousands of individual neurons in human participants through the lab\u2019s brain-computer interface (BCI) clinical trials and other neurosurgical opportunities. By identifying the encoding scheme for specific concepts across the neural ensemble, this work will advance our understanding of the computational basis of human language.

Traditionally, scientists have averaged brain activity across many trials and individuals, which hides important differences. The Williams lab develops new computational methods to capture unique patterns of neural activity in individual animals and behavioral trials. By doing so, they aim to uncover how differences in brain activity relate to differences in behavior, and to distinguish between healthy variability and signs of dysfunction.<\/p>\n
To achieve these goals, the Williams lab develops novel statistical methods and theoretical frameworks that apply broadly across different brain areas, model organisms, and behavioral protocols. Their past work has developed approaches to capture moment-to-moment changes in response amplitude, timing, and recurring sequences or “motifs” in neural activity, all of which may underlie processes like learning, attention, and decision-making. In other work, they have introduced methods to describe how neural response noise is modulated by sensory and behavioral inputs, and how the structure of neural responses varies across individual animals or species. Ultimately, their work aims to provide a clearer picture of how the brain\u2019s natural variability supports flexible and robust behavior, and to deliver practical tools that can be used across many areas of neuroscience research.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div>

In her research, Dr. Annegret Falkner and her lab will investigate how hormones change neural networks and thereby affect behavior over short and long timeframes. Using new methods for behavioral quantification, she will observe and record behaviors of all kinds in freely-behaving animals during a hormone state-change; map neural dynamics of hormone-sensitive networks across a hormone state change; and use site-specific optical hormone imaging to observe where and when estrogen-receptor-mediated transcription occurs within this network \u2013 a window into how hormones are able to update network communication, and one which will help researchers understand the profound ways hormones affect the brain and behavior.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div>

Not only might this help us learn more about how the brain works, but it may also aid in the development of next-generation therapeutics.<\/p>\n
Psychedelics have long-lasting structural effects on neurons, such as increased neuronal process outgrowth and synapse formation. A single dose can have months-long effects. In her research, Dr. Gomez and her team will use psychedelics to identify classes of RNA that promote neural plasticity in the prefrontal cortex. Gomez\u2019s lab will assess how psychedelics change how RNA is spliced, establish the link between psilocybin-induced RNA changes and plasticity in mice as measured by synaptic activity, and observe the effect of psychedelic-induced plasticity on social interaction.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div>

Mammals that specifically evolved to maintain a constant body temperature abruptly \u201cswitch off\u201d that feature, change their metabolism, and change their behavior for months at a time. While the facts of hibernation are well understood, how animals initiate and maintain that state is not well understood, nor is how this ability arose.<\/p>\n
Dr. Sinisa Hrvatin proposes to delve into the neuronal populations and circuits involved in hibernation using a less-common model, the Syrian hamster. Syrian hamsters can be induced to hibernate environmentally, making them ideal for a laboratory experiment, but there are no available transgenic lines (like in mice), which led him to apply novel RNA-sensing-based viral tools to target specific cell populations related to hibernation. He will document neurons active during hibernation to identify relevant circuits and examine whether similar circuits are conserved in other hibernating and non-hibernating models.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div>

But to Dr. Xin Jin, the power of the genome is most fully realized when tools allow researchers to study a large number of genes across the brain and see where they are present and where they intersect in specific brain regions.<\/p>\n
Dr. Jin\u2019s lab has developed new massively parallel in vivo<\/em> sequencing approaches to scale up the investigation of large numbers of gene variants and map their presence in whole, intact brains. The ability to profile over 30,000 cells at once allows the team to study hundreds of genes in hundreds of cell types and get a readout in a matter of two days rather than weeks. They will conduct whole-organ surveys, demonstrating the ability to not only identify which cells include specific variants, but identify their context within the brain: where they are located and how they are connected.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div>\n\t\n\t\t\n\t\t\tAnn Kennedy, Ph.D.,<\/strong> Assistant Professor, Department of Neuroscience, Northwestern University, Chicago, IL<\/p>\nNeural Population Dynamics Mediating the Balance of Competing Survival Needs <\/em><\/p>\nTo survive, animals have evolved a wide range of innate behaviors such as feeding, mating, aggression and fear responses. Researchers have been able to record neural activity in mouse models while they are engaged in these kinds of behaviors. But in the real world, animals often have to weigh and decide between multiple urgent courses of action.<\/p>\n
Dr. Ann Kennedy is engaged in developing theoretical computational models that will help advance our understanding of how important decisions like these are made. Looking at the neural activity in the hypothalamus of mice engaged in aggression-type behavior, Dr. Kennedy and her team will develop neural network models that capture the scalability and persistence of aggressive motivational states, while also providing a mechanism for trading off between multiple competing motivational states in the animal\u2019s behavior.

Working with a fruit fly model and a new, innovative experimental apparatus, Dr. Sung Soo Kim and his team will investigate what is happening in the brain when navigating.<\/p>\n
Dr. Kim will investigate how multiple sensory inputs are transformed into a sense of direction and how behavioral contexts affect direction processing. A key to this research is a novel virtual reality arena Dr. Kim\u2019s team is building with a very large microscope overhead means the entire brain of the fly can be imaged even as it turns. By activating and silencing certain neuronal populations, Dr. Kim will be able to conduct research that looks at the combined role of perception, cognition, and motor control.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div>

Recent research seems to suggest that it can, and Dr. Bianca Jones Marlin and her team are prepared to investigate how experiences that induce fear or stress in a mouse model can cause changes to the very neurons present in its brain, and how those changes can be genetically inherited by the children of the animal that experienced the stress.<\/p>\n
Dr. Marlin\u2019s research draws on the discovery that changes in the environment lead to experience-dependent plasticity in the brain. Using olfactory fear conditioning, the team has learned that mice will produce more olfactory neurons attuned to the odor used. That higher ratio persists, is encoded in sperm, and is passed down to the next generation (but not subsequent generations.) Dr. Marlin\u2019s lab will research the process on a molecular level which she hopes not only aids researchers, but also raises awareness of the effects of trauma.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div>

It sits at a vertex with other cognitive abilities, including memory and executive control, and underpins both our individual and societal intelligence. Due to the lack of animal models and the rarity of human brain recording, little is known about the biological basis of language at the resolution of circuit computation \u2013 individual neurons.\u00a0\u00a0Moreover, we have no technologies to repair the devastating loss of the ability to communicate through language due to neurological injury.<\/p>\n Dr. Stavisky and his team hope to address this neuroscientific and medical gap by identifying the neural representations of semantic features across the brain\u2019s language network. They will record from thousands of individual neurons in human participants through the lab\u2019s brain-computer interface (BCI) clinical trials and other neurosurgical opportunities. By identifying the encoding scheme for specific concepts across the neural ensemble, this work will advance our understanding of the computational basis of human language. It may also point to better architectures for artificial intelligence systems. Last but not least, this project aims to develop a language neuroprosthesis that will enable individuals suffering from language disorders to effectively communicate.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div> Alex Williams, Ph.D.<\/a><\/strong>, Assistant Professor, New York University and the Flatiron Institute, New York, NY<\/p>\n Computational Methods to Characterize Variability in Large-Scale Neural Circuits<\/em><\/p>\n Dr. Williams investigates how large networks of neurons can function reliably, even though both the brain and behavior are naturally variable and often noisy. Traditionally, scientists have averaged brain activity across many trials and individuals, which hides important differences. The Williams lab develops new computational methods to capture unique patterns of neural activity in individual animals and behavioral trials. By doing so, they aim to uncover how differences in brain activity relate to differences in behavior, and to distinguish between healthy variability and signs of dysfunction.<\/p>\n To achieve these goals, the Williams lab develops novel statistical methods and theoretical frameworks that apply broadly across different brain areas, model organisms, and behavioral protocols. Their past work has developed approaches to capture moment-to-moment changes in response amplitude, timing, and recurring sequences or “motifs” in neural activity, all of which may underlie processes like learning, attention, and decision-making. In other work, they have introduced methods to describe how neural response noise is modulated by sensory and behavioral inputs, and how the structure of neural responses varies across individual animals or species. Ultimately, their work aims to provide a clearer picture of how the brain\u2019s natural variability supports flexible and robust behavior, and to deliver practical tools that can be used across many areas of neuroscience research.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div> Annegret Falkner, Ph.D<\/strong><\/a>., <\/strong>Assistant Professor, Princeton Neuroscience Institute, Princeton University, Princeton, NJ<\/p>\n Computational Neuroendocrinology: Linking Hormone-Mediated Transcription to Complex Behavior Through Neural Dynamics<\/em><\/p>\n Gonadal hormones \u2013 estrogen and testosterone are among the best known \u2013 are important to mammals in many ways. They modulate internal states, behavior, and physiology. But while much has been studied about how these hormones affect the body, less well understood is how they change neural dynamics.<\/p>\n In her research, Dr. Annegret Falkner and her lab will investigate how hormones change neural networks and thereby affect behavior over short and long timeframes. Using new methods for behavioral quantification, she will observe and record behaviors of all kinds in freely-behaving animals during a hormone state-change; map neural dynamics of hormone-sensitive networks across a hormone state change; and use site-specific optical hormone imaging to observe where and when estrogen-receptor-mediated transcription occurs within this network \u2013 a window into how hormones are able to update network communication, and one which will help researchers understand the profound ways hormones affect the brain and behavior.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div> Andrea Gomez, Ph.D.,<\/strong><\/a> Assistant Professor, Neurobiology, University of California, Berkeley, CA<\/p>\n The Molecular Basis of Psychedelic-Induced Plasticity<\/em><\/p>\n The brain possesses the ability to change itself, a feature described as \u201cplasticity.\u201d Dr. Andrea Gomez aims to learn more about brain plasticity by using psychedelics as a tool, reopening plasticity windows in the adult brain using the psychedelic psilocybin in a mouse model. Not only might this help us learn more about how the brain works, but it may also aid in the development of next-generation therapeutics.<\/p>\n Psychedelics have long-lasting structural effects on neurons, such as increased neuronal process outgrowth and synapse formation. A single dose can have months-long effects. In her research, Dr. Gomez and her team will use psychedelics to identify classes of RNA that promote neural plasticity in the prefrontal cortex. Gomez\u2019s lab will assess how psychedelics change how RNA is spliced, establish the link between psilocybin-induced RNA changes and plasticity in mice as measured by synaptic activity, and observe the effect of psychedelic-induced plasticity on social interaction.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div> Sinisa Hrvatin, Ph.D<\/strong><\/a>., <\/strong>Assistant Professor of Biology, Whitehead Institute for Biomedical Research, Massachusetts Institute of Technology, Cambridge, MA<\/p>\n Molecular Anatomy of Hibernation Circuits<\/em><\/p>\n Most people understand the concept of hibernation, but relatively few think about how remarkable it is. Mammals that specifically evolved to maintain a constant body temperature abruptly \u201cswitch off\u201d that feature, change their metabolism, and change their behavior for months at a time. While the facts of hibernation are well understood, how animals initiate and maintain that state is not well understood, nor is how this ability arose.<\/p>\n Dr. Sinisa Hrvatin proposes to delve into the neuronal populations and circuits involved in hibernation using a less-common model, the Syrian hamster. Syrian hamsters can be induced to hibernate environmentally, making them ideal for a laboratory experiment, but there are no available transgenic lines (like in mice), which led him to apply novel RNA-sensing-based viral tools to target specific cell populations related to hibernation. He will document neurons active during hibernation to identify relevant circuits and examine whether similar circuits are conserved in other hibernating and non-hibernating models.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div> Xin Jin, Ph.D<\/strong><\/a>., <\/strong>Assistant Professor, Department of Neuroscience, The Scripps Research Institution, La Jolla, CA<\/p>\n In vivo Neurogenomics at Scale<\/em><\/p>\n When studying gene function in neurons, researchers often have to choose between scale and resolution. But to Dr. Xin Jin, the power of the genome is most fully realized when tools allow researchers to study a large number of genes across the brain and see where they are present and where they intersect in specific brain regions.<\/p>\n Dr. Jin\u2019s lab has developed new massively parallel in vivo<\/em> sequencing approaches to scale up the investigation of large numbers of gene variants and map their presence in whole, intact brains. The ability to profile over 30,000 cells at once allows the team to study hundreds of genes in hundreds of cell types and get a readout in a matter of two days rather than weeks. They will conduct whole-organ surveys, demonstrating the ability to not only identify which cells include specific variants, but identify their context within the brain: where they are located and how they are connected.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div> Ann Kennedy, Ph.D.,<\/strong> Assistant Professor, Department of Neuroscience, Northwestern University, Chicago, IL<\/p>\n Neural Population Dynamics Mediating the Balance of Competing Survival Needs <\/em><\/p>\n To survive, animals have evolved a wide range of innate behaviors such as feeding, mating, aggression and fear responses. Researchers have been able to record neural activity in mouse models while they are engaged in these kinds of behaviors. But in the real world, animals often have to weigh and decide between multiple urgent courses of action.<\/p>\n Dr. Ann Kennedy is engaged in developing theoretical computational models that will help advance our understanding of how important decisions like these are made. Looking at the neural activity in the hypothalamus of mice engaged in aggression-type behavior, Dr. Kennedy and her team will develop neural network models that capture the scalability and persistence of aggressive motivational states, while also providing a mechanism for trading off between multiple competing motivational states in the animal\u2019s behavior. From this work, Dr. Kennedy\u2019s lab will advance our understanding of how the structure built into the brain helps animals survive.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div> Sung Soo Kim, Ph.D<\/strong><\/a>., <\/strong>Assistant Professor of Molecular, Cellular, and Developmental Biology, University of California-Santa Barbara, Santa Barbara, CA<\/p>\n Neural Representation of The World During Navigation<\/em><\/p>\n Anyone who has ever had to navigate a known but darkened room understands how valuable it is that our brains can navigate our surrounding environment using a variety of information, inside and out, including colors, shapes, and a sense of self-motion. Working with a fruit fly model and a new, innovative experimental apparatus, Dr. Sung Soo Kim and his team will investigate what is happening in the brain when navigating.<\/p>\n Dr. Kim will investigate how multiple sensory inputs are transformed into a sense of direction and how behavioral contexts affect direction processing. A key to this research is a novel virtual reality arena Dr. Kim\u2019s team is building with a very large microscope overhead means the entire brain of the fly can be imaged even as it turns. By activating and silencing certain neuronal populations, Dr. Kim will be able to conduct research that looks at the combined role of perception, cognition, and motor control.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div> Bianca Jones Marlin, Ph.D<\/strong><\/a>., <\/strong>Assistant Professor of Psychology and Neuroscience, Columbia University and the Zuckerman Mind Brain Behavior Institute, New York, NY<\/p>\n Molecular Mechanisms of Intergenerational Memory<\/em><\/p>\n Can the memory of a stressful experience be inherited by the next generation? Recent research seems to suggest that it can, and Dr. Bianca Jones Marlin and her team are prepared to investigate how experiences that induce fear or stress in a mouse model can cause changes to the very neurons present in its brain, and how those changes can be genetically inherited by the children of the animal that experienced the stress.<\/p>\n Dr. Marlin\u2019s research draws on the discovery that changes in the environment lead to experience-dependent plasticity in the brain. Using olfactory fear conditioning, the team has learned that mice will produce more olfactory neurons attuned to the odor used. That higher ratio persists, is encoded in sperm, and is passed down to the next generation (but not subsequent generations.) Dr. Marlin\u2019s lab will research the process on a molecular level which she hopes not only aids researchers, but also raises awareness of the effects of trauma.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div>2024-2026<\/h3>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div>
