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

Directional pursuit deficits following lesions of the foveal representation within the superior temporal sulcus of the macaque monkey.
TL;DR: The errors in pursuit speed and saccade amplitude for initiation of pursuit into the contralateral visual field were linearly related, which supports the hypothesis that both deficits arise from damage to the same underlying visual motion processing mechanism.

TL;DR: The correlation of fMRI data with connectional data showed that visual action information, encoded in the STS, is forwarded to ventral premotor cortex (F5) along two distinct functional routes that emphasizes the object of the action and may aid in understanding motor acts with respect to their immediate goal.

Receptive-field properties of neurons in middle temporal visual area (MT) of owl monkeys.
Daniel J. Felleman,Jon H. Kaas +1 more
TL;DR: Response properties of single neurons in the middle temporal visual area of anesthetized owl monkeys were determined and quantified for flashed and moving bars of light under computer control for position, orientation, direction of movement, and speed.

Navigating the Neural Space in Search of the Neural Code.
Mehrdad Jazayeri,Arash Afraz +1 more
TL;DR: It is noted that the brain functions at multiple scales and that causal dependencies may be best inferred with perturbation tools that interface with the system at the appropriate scale, and a geometric framework is developed to facilitate the interpretation of causal experiments when brain perturbations do or do not respect the intrinsic patterns of brain activity.

Motion distorts visual space: shifting the perceived position of remote stationary objects.
David Whitney,Patrick Cavanagh +1 more
TL;DR: The results indicate that motion's influence on position is not restricted to the moving object itself, and that even the positions of stationary objects are coded by mechanisms that receive input from motion-sensitive neurons.

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.
