Direct recordings in human cortex reveal the dynamics of gamma-band [50–150Hz] activity during pursuit eye movement control

The time course of neural activity in human brain regions involved in mediating pursuit eye movements is unclear. To address this question, we recorded intracerebral electroencephalography activity in eight epileptic patients while they performed a pursuit task that dissociates reactive, predictive and inhibited pursuits. A sustained gamma band (50–150 Hz) activity corresponding to pursuit maintenance was observed in the pursuit (and not...
