DESCRIPTION OF GRADUATE RESEARCH
My primary interest is in investigating the neural systems involved in visual perception. I study a paradigm called binocular rivalry, which involves sensory competition of visual inputs that are incompatible. Through the vacillating response patterns of the neurons in visual cortex we can identify what internal dynamics are generated by the brain to produce stabilized visual percepts, and what competitive processes are involved in changing them. In healthy human subjects I use EEG and fMRI to assess the dynamic patterns of activation that are a result of the activity in large scale neural ensembles. Specifically, I have been investigating how natural oscillatory bands in the EEG are organized in relation to competing perceptual states in binocular rivalry.  Recent advancements in oscillatory EEG activity are becoming increasingly suggestive of a role for theta, alpha, beta, and gamma oscillatory networks in perception, so my goal is to identify specific functions for each of these bands in the dynamics of binocular rivalry.
