I am interested in understanding the neural mechanisms underlying the acquisition, consolidation, and retrieval of fear memories. Recent evidence suggests that the neurotransmitter acetylcholine modulates the activity of fear-related neural structures to affect fear learning. The most significant source of this acetylcholine comes from cholinergic neurons in the forebrain region. My PhD research project is currently investigating the role of these forebrain cholinergic neurons in the acquisition and extinction of fear memories.
