Michael Petrides, PhD
Professor
Michael Petrides is examining the function of the different areas of the frontal cortex and their interaction with parietal and temporal areas in cognitive activity, particularly planning and working memory. For instance, he has shown that the ability to monitor self-generated, intentional actions in working memory depends on a specific part of the dorsolateral frontal cortex, which interacts with the parietal cortex during the mental manipulation of information. He also examines the cytoarchitecture and connectivity of the different cortical areas. Petrides is also studying single cells in this region of the brain to determine the specific neural activity that underlies working memory monitoring.
