The responses of 81 cells from area 17 in paralysed and aneasthetized cats were studied
with moving spots and moving bars of different lengths. Tuning curves were measured and …

A variably oriented test grating was presented for identification in angular degrees
immediately following 5-s exposure to a high-contrast grating of the same spatial frequency …

Measurements were made of the optimal velocity for drifting bar-shaped stimuli to excite
striate cortex neurons of the cat. These data were compared to the optimal spatial and …

Perceptual re-organization in reversible figures is tested by a selective adaptation paradigm,
using the rate of apparent alternation as an index of the adaptation in directionally sensitive …

Adaptation to a grating of bright and dark stripes temporarily raises the identification
threshold of spatial gratings with the same orientation. Gilinsky (1968). who first reported the …

Our previous two studies have shown that dark-rearing affects the morphology and
chemistry of adult rat primary visual cortex (area 17). In this study we demonstrate correlated …

It is still unclear how sensory systems efficiently encode signals with statistics as
experienced by animals in the real world and what role adaptation plays during normal …

Single cell responses to moving visual stimuli have been recorded in the striate cortex of
anaesthetized and immobilized cats, and the effects of the reversal of stimulus contrast have …

The cerebellum is well suited for controlling visually guided movements and for asserting a
role in visuo-motor transformations. We are assessing the contribution of the cerebellum to …

METHODS Two rhesus monkeys, Macaca mulatta, were used in these experiments. The
methods used for training the monkey to look at a fixation point, for restraining the monkey …
