Motion after-effects were elicited from striate cortical cells in lightly-anaesthetized cats, by
adapting with square-wave gratings or randomly textured fields drifting steadily and
continuously in preferred or null directions. The time-course and recovery of responsiveness
following adaptation were assessed with moving bars, gratings or textured fields. Results
were compared with controls in which the adapting stimulus was replaced by a uniform field
of identical mean luminance, and also assessed in relation to the strength and time course …

Interocular transfer of motion after-effects was assessed in the lightly-anaesthetized feline
striate cortex. Neurones were adapted with squarewave gratings of optimal orientation and
spatial frequency, or with randomly textured fields, drifting continuously at optimal velocity in
their preferred or null directions. Neural after-effects were assessed as consequent changes
in directional bias, using similar test patterns swept back-and-forth in the same directions
and presented to the same or opposite eyes. All results were compared with controls …
