James Chrobak

Degree: Ph.D., Experimental Psychology, 1988, UNC-Chapel Hill
Research Interests: Making memories in the mammalian brain; the physiology and function of the hippocampus and interconnected forebrain circuits.
Research Synopsis: My research is currently focused on 1) describing variation in neuronal synchronization across the septotemporal axis of the hippocampus, 2) how that variation is altered by environmental phenomenon, the animals behavior as well as pharmacological manipulations and 3) how that variation may relate to episodic memory formation.
