Mechanisms of direction selectivity and speed selectivity were studied in single neurons of
the middle temporal visual area (MT) of behaving macaque monkeys. Visual stimuli were …

The invitation by the editors of the series" studies of brain function" to contribute a
monograph on the visual cortex gives me the opportunity to present in a concentrated …

This book presents an interdisciplinary overview of the main facts and theories that guide
contemporary research on visual perception. While the chapters cover virtually all areas of …

Differential velocity detection in the fovea was measured over a wide range of velocities
(0.25–256°/sec), Differential thresholds were minimum (about 6%) for intermediate velocities …

Human observers can discriminate a 5% difference in velocity for a wide range of velocities.
Using an apparent-motion stimulus, we demonstrated that velocity discrimination depends …

To answer the question whether OFF response amplitude (firing rate) of visual cortical cells
varies as a function of stimulus duration, a series of such cells from areas 17 and 18 of the …

In order to evaluate their possible role in visible persistence, cortical cells from area 17 of the
cat were investigated with a stationary light bar flashed for different durations. Thirteen out of …

Decreasing the visual sampling rate by reducing the stroboscopic frequency affected the
postural performance of human subjects. At low strobe frequencies of up to 2 flashes/sec., at …

In the cat, cells of the superior colliculus (SC) and the tectofugal pathways of the visual
system are highly selective for the direction of a moving visual stimulus. Deep layer units of …
