Learning and Spatial Coding in the Hippocampal-Cortical Circuit

Molecular Mechanisms of Synaptic Plasticity and Neurodegeneration

Neural Circuitry of Motivation

Cortical-subcortical networks for sensory processing and behavior

The Synaptic Basis of Behavior

    The nervous system encodes information through the timing and frequency of action potentials.  Synapses process this input by determining which features of the firing pattern release neurotransmitter. However, we do not understand the molecular mechanisms responsible for extracting this information, making it difficult to understand the function of neural circuits, their role in behavior and their dysfunction in neuropsychiatric disease.

Synaptic Interactions in the Retina: Pathways and Mechanisms

Speech Mechanisms

A unique and defining trait of human behavior is our ability to communicate through speech. My laboratory is interested in determining the basic mechanisms that underlie speech perception and production.  While much of this processing has been localized to the peri-sylvian cortex, including Broca’s and Wernicke’s areas, the fundamental organizational principles of these neural circuits are completely unknown.

Sensorimotor Learning in the Song System

Research in my laboratory focuses primarily on the question of how experience, particularly during early life, shapes the functioning of the nervous system. To approach this question we are currently using a combination of behavioral and neurophysiological techniques to investigate the mechanisms underlying vocal learning in songbirds.
