Upper Video:
Propagating activity in response to a grating moving
either rightwards (left frame) or downwards (right
frame) in the visual field. Only oscillatory activity
components are shown here. Note that activity for the
rightward moving stimulus appears propagating in
leftward direction because rostral is at bottom
(right hemisphere, M=medial, P=posterior).
Lower
Video: The above propagating waves of activity
are shown overlaid on tonic activity components
representing the orientation maps. Hence, these stationary
maps encode the orientation of the grating simultaneously
to its motion. Black outlines are
drawn at 90th activity percentiles of the tonic
components.
