OverviewAI-generated summary
Srimoy Chakraborty's research focuses on understanding the dynamics of neural networks, particularly in the cerebral cortex. His work investigates the concept of criticality, a state theorized to optimize information processing and dynamic range in neuronal systems. This research is supported by federal grants from the National Institutes of Health (NIH), including a $295,122 award from the National Institute on Drug Abuse for studying tunable multi-timescale cortical dynamics and a $450,000 award from the National Institute of Neurological Disorders and Stroke for investigating high-dimensional motor coding and motor dysfunction in Rett syndrome.
Chakraborty's publications explore themes such as neuronal avalanches, their implication for maximum dynamic range, and the functional benefits of criticality in cortical networks. He has also examined how adaptation to sensory input tunes the visual cortex to criticality and how voltage imaging of the waking mouse cortex reveals critical neuronal dynamics. His work considers the effects of topology on criticality and dynamic range in complex networks.
His scholarly output includes a total of four publications with 31 citations and an h-index of 2. Chakraborty collaborates with several researchers at the University of Arkansas at Fayetteville, including Shree Hari Gautam, Antonio J. Fontenele, J. Samuel Sooter, and V. Kindler Norman, with whom he shares multiple joint publications. He maintains an active lab website to disseminate his research.
