Field of Research

We investigate the cellular and synaptic basis of learning and memory processes. We focus on classical (Pavlovian) fear conditioning and its extinction in mice, which are powerful models for associative learning and memory. The key brain structure implicated in acquisition and storage of fear memory is the amygdala. Some of the strongest links between synaptic and cellular plasticity and behavioural learning come from studies of sensory inputs to the amygdala. Our aim is to study other elements of the amygdaloid network, including inhibitory elements, and their interactions with other amygdala input and output structures. Understanding fear and extinction memory is not only an excellent model for general principles of memory formation in the brain, but will also provide leads on nervous system dysfunction during inappropriate control of fear behavior in conditions such as human anxiety disorders.
