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

Common and distinct neural mechanisms of visual and tactile extinction: A large scale VBM study in sub-acute stroke
Magdalena Chechlacz,Anna Terry,Nele Demeyere,Nele Demeyere,Hassan Douis,Hassan Douis,Wai-Ling Bickerton,Pia Rotshtein,Glyn W. Humphreys,Glyn W. Humphreys +9 more
TL;DR: It is concluded that extinction in different modalities emerges after damage to both common (supra-modal) and distinct (modality specific) brain regions, and that contrasting sites emerge afterDamage to different vascular territories.

Relationship between size summation properties, contrast sensitivity and response latency in the dorsomedial and middle temporal areas of the primate extrastriate cortex.
TL;DR: The results are partially consistent with a hierarchical model whereby more extensive receptive fields require convergence of information from larger pools of “feedforward” afferent neurons to reach near-optimal responses, and suggest that a common gain normalization mechanism within MT and DM is involved.

Behavioral time course of microstimulation in cortical area MT.
Nicolas Y. Masse,Erik P. Cook +1 more
TL;DR: The results suggest the behavioral effects of microstimulation in the experiments were caused by the unique and long-lasting temporal effects micro Stimulation has on functioning cortical circuits.

The effect of timing and spatial separation on the velocity of auditory apparent motion
TL;DR: Results suggest that velocity is possibly a primary dimension of AAM that is independent of source separation, and duration estimates were related only to total duration, but separation estimates wererelated to both separation and total duration.

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.
