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

Deep tectal cells in pigeons respond to kinematograms
TL;DR: It is demonstrated that deep tectal neurons in pigeons respond equally well to kinematograms as they do to traditional luminance contrast stimuli typically employed in visual experiments, and this similarity included directional selectivity, the in-phase inhibition anti-phase facilitation effect, and sensitivity to opposed motion independent of direction.

Distributed Population Mechanism for the 3-D Oculomotor Reference Frame Transformation
TL;DR: The mechanism for visuomotor reference frame transformations identified here is the same solution used in the real brain, and the hidden units developed complex, eye-centered visual receptive fields, widely distributed fixed-vector motor commands, and "gain field"-like eye position sensitivities.
Subcortical connections of area V4 in the macaque
TL;DR: Retrograde and anterograde tracers are injected in different topographical regions of V4 in nine macaques to determine the organization of its subcortical connections and any role in spatial attention is less spatially specific.

Similarity in the response of smooth pursuit and manual tracking to a change in the direction of target motion.
TL;DR: The data suggest that the neural mechanisms for smooth pursuit and manual tracking have common functional elements and that musculoskeletal dynamics do not appear to be a rate-limiting factor.

Isoluminance and chromatic motion perception throughout the visual field.
Lynda Bilodeau,Jocelyn Faubert +1 more
TL;DR: It is proposed that the lower visual field and not the superior visual field is specialized for colour motion information, and the inferior visual field was found to be the most sensitive to chromatic motion.

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.
