Spontaneous modulations of high-frequency cortical activity.

ABSTRACT:

Objective

We clarified the clinical and mechanistic significance of physiological modulations of high-frequency broadband cortical activity associated with spontaneous saccadic eye movements during a resting state.

Methods

We studied 30 patients who underwent epilepsy surgery following extraoperative electrocorticography and electrooculography recordings. We determined whether high-gamma activity at 70-110 Hz preceding saccade onset would predict upcoming ocular behaviors. We assessed how accurately the model incorporating saccade-related high-gamma modulations would localize the primary visual cortex defined by electrical stimulation.

Results

The dynamic atlas demonstrated transient high-gamma suppression in the striatal cortex before saccade onset and high-gamma aug
