Working memory and the fronto-parietal network

Understanding the neuronal dynamics underlying cognition has been my focus in neuroscience. Cognition relies on neuronal processes distributed throughout the brain. However, little is known about how these processes are interacting and integrated in a coherent manner to be functional. We use electrophysiological and computational techniques to characterize these dynamics and mathematical simulations to test their theoretical implications. We are currently investigating visual working memory processes in the fronto-parietal network by characterizing the properties of coherent oscillations of the network and of the participating neurons. The goal of this research is to uncover large-scale spatio-temporal patterns of neuronal activity underlying short-term memory representations, a fundamental cognitive ability necessary to many executive functions.
