TLDR
The presence of both direction and speed selectivity in MT of the macaque suggests that this area is more specialized for the analysis of visual motion than has been previously recognized.Abstract:
1. Recordings were made from single units in the middle temporal visual area (MT) of anesthetized, paralyzed macaque monkeys. A computer-driven stimulator was used to make quantitative tests of sel...read more

Spatial Summation, End Inhibition and Side Inhibition in the Middle Temporal Visual Area (MT)
TL;DR: These results demonstrate distinct patterns of spatial selectivity in MT, supporting the notion that neurons in this area can perform various roles in terms of grouping and segmentation of motion signals.
Journal ArticleDOI
Perceptual, Oculomotor, and Neural Responses to Moving Color Plaids:
TL;DR: These neurophysiological results demonstrate that the neural mechanism for motion coherence is sensitive to the phase relationship between chromatic and luminance contrast, a finding which has implications for interactions between ‘color’ and ‘motion’ processing streams in the primate visual system.
Journal ArticleDOI
Computing motion in the primate's visual system.
TL;DR: A single unifying principle 'the final optical flow should be as smooth as possible' (except at isolated motion discontinuities) explains a large number of phenomena and links single-cell behavior with perception and computational theory.
Journal ArticleDOI
Representing retinal image speed in visual cortex.
TL;DR: Speed preferences in MT neurons are found to be unaffected by changes in stimulus pattern, supporting the hypothesis that these neurons represent retinal image velocities.

TL;DR: It is concluded that main aspects of visual function are preserved despite sizable representation abnormalities in the ventral visual processing stream, which indicates largely unaltered cortico‐cortical connections in both types of misrouting.

Receptive fields and functional architecture of monkey striate cortex
David H. Hubel,Torsten N. Wiesel +1 more
TL;DR: The striate cortex was studied in lightly anaesthetized macaque and spider monkeys by recording extracellularly from single units and stimulating the retinas with spots or patterns of light, with response properties very similar to those previously described in the cat.

Silver Staining of Myelin by Means of Physical Development
TL;DR: For staining myelin with silver a physical development technique has been devised that can render visible the thinnest fibers in various animal species, including fishes and reptiles, even in the early phase of myelination and may be applied to both frozen and embedded materials.
