Beta oscillations in frontal cortex and striatum represent post-processing of successful behavior
Beta band (13-30 Hz) oscillations in sensorimotor cortex are associated with motor performance, but the nature of this relationship is not clear. Recently, excessive beta activity in cortico-basal ganglia circuits has been recognized as a hallmark of Parkinson's disease. Renewed interest in beta …

Brain Rhythms in Object Recognition and Manipulation
… training in virtual reality, I demonstrated that beta oscillations are crucial to the retrieval of object knowledge during object recognition. Multiple evidence points toward an access to object knowledge during the 300 to 400 ms of visual processing. The different topographies of the beta …

Large-scale neural recordings and biophysical models for inferring network mechanisms of ketamine anesthesia
… doses, ketamine generates robust gamma oscillations between 30-80 Hz that are typical of active, structured cognition; yet, under ketamine, gamma oscillations persist into profound sedation and anesthetic unconsciousness. Here, I use experimental and computational approaches to …

Neural circuits for solving the cocktail party problem in mouse auditory cortex
… cortex (mPFC). Results show that alpha and beta oscillations (8-18 Hz) in response to unrewarded tones exhibited immediate and robust increases in both regions prior to behavioral changes. When subjects learned to suppress behavioral responses, coherence at 8-18 Hz between ACx and mPFC was …
