Dr. Rakitin is a Columbia College graduate who obtained his Ph.D. at the University of Oregon’s McDonnel-Pew Center for the Cognitive Neuroscience of Attention. Dr. Rakitin’s was awarded McDonnel-Pew and NSF graduate research fellowships, and completed a postdoctoral fellowship in the New York State Psychiatric Institute’s Developmental Psychobiology division. He has been a member of the faculty of the Taub Institute’s Cognitive Neuroscience Division since 2000.

Ongoing Research

Currently, Dr. Rakitin studying Parkinson’s disease patients in collaboration with Dr. Karen Marder using a new, more sensitive behavioral timing battery that can reveal deficits in medicated patients. These findings allow us to pursue new avenues of inquiry including the relation between timing deficits, olfaction deficits and functional impairments that have implications for clinical rehabilitation. A study of HD disease patients and carriers of the HD gene using behavioral timing and brain imaging technology is in the planning stage. Most recently Dr. Rakitin has begun to examine the relations between proaction, defined as planned, timed behavior, and reaction, or behavior elicited in response to a stimulus. The goal is to understand how these two fundamental modes of action interact with each other, and mediate age related changes to cognition.

They recently completed a series of experiments using a task switching and conflict paradigm developed by our colleague Etienne Koechlin to study executive function using methods. This paradigm, along with a delayed item recognition task, form the backbone of the Division’s investigations of cognitive reserve, defined by Dr. Stern as a key factor mediating the behavioral and clinical manifestation of age-related brain pathology. Dr. Rakitin is also a collaborator in the groundbreaking collaboration between Dr. Stern and Dr. Timothy Salthouse, University of Virginia, investigating reference ability neural networks (RANN), the putative brain underpinnings of the basic cognitive abilities identified by Dr. Salthouse as explaining the majority of age-related cognitive decline.
