1. Responses of single cortical neurons in area 17 of anesthetized cats were recorded in
response to prolonged stimulation with a patch of drifting square-wave grating. 2. During …

1. The selectivity of adaptation to unidirectional motion was examined in neurons of the cat
striate cortex. Following prolonged stimulation with a unidirectional high-contrast grating, the …

1. Responses of simple cells in cat striate cortex were studied with flashed light-slit stimuli.
The responses to bars flashed in different positions in the receptive field were assessed …

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 …

Neurons in area 17 of the cat visual cortex adapt when stimulated by drifting patterns of
optimal orientation, spatial frequency and temporal frequency (Ohzawa et al. 1982; Albrecht …

Cat striate cortical neurons were investigated using a new method of studying adaptation
aftereffects. Stimuli were sinusoidal gratings of variable contrast, spatial frequency, and drift …

1. Direction-selective properties of neurons in cat striate cortex (area 17) were studied with
flashed and continuously moving bar stimuli. Receptive fields were characterized by …

Adaptation-induced changes in the temporal-frequency tuning and direction selectivity of cat
visual cortical cells were studied. Aftereffects were induced largely independent of direction …

In contrast to neurons of the lateral geniculate nucleus (LGN), neurons in the primary visual
cortex (V1) are selective for the direction of visual motion. Cortical direction selectivity could …

Responses of striate cortical neurones to bars of optimal orientation and width, moving with
fixed velocity, were recorded in the lightly anaesthetized cat. Effects of periods of pre …
