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

Spatiotemporal properties of apparent motion perception and aging.

TL;DR: The results show that the maximum temporal interval and maximum spatial displacement over which two frames can be integrated are reduced in older age.

A comparison of global motion perception using a multiple-aperture stimulus
Alan L. F. Lee,Hongjing Lu +1 more
TL;DR: It is found that human sensitivity for all motion types remained constant across a range of motion sampling density but varied depending on global speed, which is consistent with physiological and computational evidence suggesting that specific mechanisms exist for processing complex circular/radial motion.

Smooth pursuit initiation in young and elderly subjects.
Mark J. Morrow,James A. Sharpe +1 more
TL;DR: Older subjects had significant reductions in initial pursuit acceleration before saccades, and in post-saccadic and peak pursuit velocities, implying defective use of visual motion information by the saccadic system.

Directional tuning of motion-sensitive cells in the anterior superior temporal polysensory area of the macaque.
TL;DR: The early response latency and directional selectivity indicate that motion sensitivity in STPa cells derives from the dorsal visual pathway via MT/MST, and the similarity of tuning for direction and perspective view within STPa may facilitate the integration of motion and form processing within this high-level brain area.

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.
