Ryan A. Wirt and James M. Hyman (both Psychology) have . Over time, contextual memories become dependent on the anterior cingulate cortex (ACC) for retrieval. Wirt and Hyman found that theta-mediated interactions between ACC and CA1 increase for remote recall. Communication from the ACC to CA1 modulates neural oscillations and unit spiking, leading to enhanced CA1 contextual information. Wirt is a graduate student.
