Summary

This project will use intracranial recordings and stimulation of the human brain to understand the unique contributions of the posterior cingulate cortex (PCC) to episodic memory behavior. The goal is to test how distinct subregions of the PCC differentially contribute to memory-based decisions (e.g., have I seen this picture before?). The ability to perform invasive studies of the human brain is through routine clinical monitoring of brain activity which occurs during the neurosurgical treatment of epilepsy. However, this project only focuses on the basic science of PCC and memory behavior. Specifically, the investigators will use single-0cell and population measures of brain activity to test a new theory of PCC function which focuses on the executive processes needed to support memory retrieval and memory-based decisions. By studying the PCC, a convergence zone of memory and executive brain systems, progress can be made in elucidating how the failure to successfully leverage past experiences in daily behavior can occur as a common symptom of both neurodegenerative disease (e.g., Alzheimer's disease) and multiple psychiatric conditions (e.g., schizophrenia) implicating PCC dysfunction.
