Research interests:

In my laboratory, we study the neurobiological basis of emotions. We combine behavioral, electrophysiological and pharmacological tools to assess how emotions alters neural mechanisms that subserv learning and memory.

We focus on studying the interaction between the amygdala and the medial prefrontal cortex; two brain structures implicated in emotions and memory processes, and how a negative emotional event (exposure to stress) remodel differentially learning and memory circuits in these regions.

We are also interested in studying the role of the medial prefrontal cortex in mediating processes that underlie fear conditioning and extinction.

Key words: emotions, plasticity, memory, medial prefrontal cortex, amygdala, consolidation, extinction.


Current projects:


1)   Electrophysiological characterization of the pathway emerging from the medial prefrontal cortex to the basolateral amygdala and its relevance to emotions.

2)   The role of the medial prefrontal cortex in fear conditioning and extinction. This project is in collaboration with Dr. Irit Akirav from the laboratory of Prof. Yadin Dudai from the Weizmann Institute, Rehovot.

3)   The role of PKA within the medial prefrontal cortex in fear conditioning and extinction. This project is in collaboration with the laboratory of Prof. Gal Richter-Levin.
