The visual cortex produces gamma band echo in response to broadband visual flicker
Fig 4
Topographies and source modelling of the gamma echo and induced gamma oscillations.
(A) The topography and the source modelling (LCMV beamformer) of the peak amplitude of the gamma echo (0.04–0.08 s) for the right flickering stimuli. (B) Same as (A) but for left flickering stimuli. (C) The topography and source modelling of the power (DICS beamformer) of the induced gamma oscillations within range 40–100 Hz.
