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

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 …

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

Neuronal spatial frequency tuning in primary visual cortex (V1) substantially changes over
time. In both primates and cats, a shift of the neuron's preferred spatial frequency has been …

In the adult brain, sensory cortical neurons undergo transient changes of their response
properties following prolonged exposure to an appropriate stimulus (adaptation). In cat V1 …

Adaptation, the prolonged presentation of stimuli, has been used to probe mechanisms of
visual processing in physiological, imaging, and perceptual studies. Previous …

The spatial-frequency (SF) tuning of neurons in the early visual cortex is adjusted for
stimulus contrast. As the contrast increases, SF tuning is modulated so that the transmission …

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 …

Orientation-selective neurons shift their preferred orientation after being adapted to a
nonpreferred orientation. These shifts of the peaks of tuning curves may be in the attractive …
