R. Alison Adcock M.D., Ph.D.

Department of Psychiatry and Behavioral Sciences

We study how the neuromodulatory systems shape models of the world held in long-term memory. Our approach uses human brain imaging to study explicit and implicit behavior during the active acquisition of information. We hope to leverage our findings into "behavioral neurostimulation" strategies for better mental health and educational practice.

Jeff Beck, PhD

Department of Neurobiology

We are interested in how neural activity represents ecologically relevant information and how neural circuits operate on that representation in order to survive in a complex and uncertain world.  This involves the study of probabilistic inference and machine learning, decision making under uncertainty, complex (often Bayesian) behavioral models, information and coding theory, and statistical (latent state space) analysis of neural data.  Using these tools, we collaborate with physiologists to identify the fundamental properties of biologically plausible neural circuits that are capable of generating observed behavior.

Vikas Bhandawat, Ph.D.

Department of Biology

We study how animal behavior emerges from the complex interaction amongst the animal's nervous systems, their muscle-body dynamics and their environment. We use fruitflies (Drosophila melanogaster) as our model organism because they perform many complex behaviors with a relatively simple brain, and because of the many genetic tools that are available in the flies.

Diego Bohorquez

Department of Medicine

Our ambition is to learn how to treat the brain from the gut. We are focused on dissecting the neural circuits that transform signals from food and/or bacteria in the gut into electrical inputs that modulate behaviors like the desire to eat. We recently discovered that, like taste cells in the tongue, the gut also has a sensory neuroepithelial circuit (J Clin Invest. 2015;125(2):782). This circuit may be the first point of integration of signals from food, bacteria, or viruses in the gut and behaviors in the brain.

Nicolas Brunel, Ph.D.

We use theoretical models of brain systems to investigate how they process and learn information from their inputs. Our current work focuses on the mechanisms of learning and memory, from the synapse to the network level, in collaboration with various experimental groups.

Nicole Calakos, M.D., Ph.D.

Department of Neurology

We all know that as part of our daily lives we are constantly interacting with our environment - learning, adapting, establishing new memories and habits, and for better or for worse, forgetting as well. At the cellular level, these processes can be encoded by changes in the strength of synaptic transmission between neurons. The process by which neuronal connections change in response to experience is known as “synaptic plasticity” and this process is a major interest of our laboratory.

Marc Caron, Ph.D.

Department of Cell Biology

We investigate the molecular bases of brain dysfunctions as they relate to neurological and neuropsychiatric disorders in genetically engineered mouse models. Our studies use biochemical, cellular and behavioral approaches to determine how new concepts of neuromodulation through GPCRs and transporters can be leveraged to develop more selective and effective therapies. 

Kafui Dzirasa, M.D, Ph.D.

Department of Psychiatry and Behavioral Sciences

We study how neuropsychiatric risk genes interact with environmental stress to modify neural circuits that underlie normal emotional and cognitive function.

Cagla Eroglu, Ph.D.

Department of Cell Biology

We investigate the cellular and molecular mechanisms that underlie synaptic connectivity in the CNS. Distinct from many other laboratories, we view astrocytes as an integral part of the synapse with roles in synapse development, function, and plasticity. Our approach involves anatomical and imaging-based assays in pure primary neuron-astrocyte cultures or genetically-modified mice. 

Greg D. Field, Ph.D.

Yiyang Gong, PhD

Department of Biomedical Engineering

We're interested in understanding brain function using a combination of genetically encoded sensors and optical techniques. We use genetically encoded tools to target neurons with specific genetic types or specific projection pathways, and use optical microscopy to measure or change the activity of the selected neurons. By employing and developing tools in both categories, we study brain circuitry by recording, perturbing, and controlling brain activity in various preparations.

Jörg Grandl, Ph.D.

Department of Neurobiology

Ion channels can be activated (gated) by various stimuli (e.g. chemicals, voltage, pressure and temperature). Whereas the mechanisms of ion channel gating by chemicals or voltage are understood in principal, the logic of ion channel activation by temperature and mechanical stimulation has remained elusive. We use a combination of high-throughput mutagenesis screens and electrophysiology to identify mechanisms of ion channel function.

We study how the developing nervous system builds neural circuits. We seek to identify cellular and molecular mechanisms that generate different types of neurons, that endow them with specific identities, and that wire them together into circuits with a coherent function. Further, we would like to know what happens to circuit function when these mechanisms go awry, as may happen in neurodevelopmental disorders.

The Meyer Lab studies RNA regulatory pathways in the nervous system. We have a particular interest in understanding how RNA methylation (m6A) controls gene expression programs in the brain to contribute to human health and disease.

Richard D. Mooney, Ph.D.

Department of Neurobiology

Our research aims to identify the neural substrates for vocal learning and communication. We use both songbird and rodents to achieve these aims. Songbirds are one of the few non-human animals that learn to vocalize and serve as the preeminent model in which to identify neural mechanisms for vocal learning. The songbird is ideal for this purpose because of its well-described capacity to vocally imitate the songs of other birds, and because its brain has a constellation of discrete, interconnected brain regions (i.e., song control nuclei, referred to collectively as the song system) that function in the patterning, perception, learning and maintenance of song.

Eva Aimable Naumann

Department of Neurobiology

The Naumann lab’s goal is to understand how neural circuits across the entire brain guide behavior and how individuality manifests within these circuits. To dissect such circuits, we use the genetically accessible, translucent zebrafish to map, monitor, and manipulate neuronal activity. By combining whole-brain imaging, behavioral analysis, functional perturbations, neuroanatomy, we aim to generate brain-scale circuit models of simple behaviors in individual brains.

Department of Biomedical Engineering

The Tadross lab develops technologies to rapidly deliver drugs to genetically defined subsets of cells in the brain. By using these reagents in mouse models of neuropsychiatric disease, his group is mapping how specific receptors on defined cells and synapses in the brain give rise to diverse neural computations and behaviors.  The approach leverages drugs currently in use to treat human neuropsychiatric disease, facilitating clinically relevant interpretation of the mapping effort.

Anne E. West, M.D., Ph.D.

Department of Neurobiology

In the West lab we study the molecular mechanisms and biological consequences of stimulus-regulated transcription in the CNS. The brain is a highly adaptable organ that is capable of converting environmental information into changes in neuronal function. Transcriptional regulators play an essential role in this process by transducing synaptic activity into changes in the regulation of neuronal gene expression programs that are required for the formation, maturation, and plasticity of synapses.

Marty Woldorff, Ph.D.

Department of Psychiatry and Behavioral Sciences

We use a combination of electrophysiological (ERP, EEG) and functional neuroimaging (fMRI) methods to study the mechanisms of attention and related cognitive processes in humans.
