Extracellular single-unit recordings were made from simple cells in area 17 of anesthetized
cats. Cells were tested with drifting gratings under control and adapted conditions …

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 …

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 …

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 …

The effects of microiontophoretic application of glutamate, GABA and the GABA antagonist,
bicuculline methiodide were tested on the degree of adaptation exhibited by striate cortical …

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 …

Spatial contrast adaptation, produced by prolonged exposure to high contrast grating
patterns, has become an important psychophysical method for isolating spatial and …

The modular layout of striate cortex is arguably a hallmark of all cortical organization.
Neurons of a given module or domain respond optimally to very few specific properties, such …

Adaptation is a ubiquitous property of the visual system. Adaptation often improves the
ability to discriminate between stimuli and increases the operating range of the system, but …

Sensory neurons display transient changes in their response properties following prolonged
exposure to an appropriate stimulus (adaptation). In adult cat primary visual cortex, spatial …
