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

Neuronal Population Coding of Movement Direction
TL;DR: The direction of movement was found to be uniquely predicted by the action of a population of motor cortical neurons that can be monitored during various tasks, and similar measures in other neuronal populations could be of heuristic value where there is a neural representation of variables with vectorial attributes.
Journal ArticleDOI
Mechanisms of Visual Attention in the Human Cortex
TL;DR: Functional brain imaging studies reveal that, both in the absence and in the presence of visual stimulation, biasing signals due to selective attention can modulate neural activity in visual cortex in several ways.
Journal ArticleDOI
The analysis of visual motion: a comparison of neuronal and psychophysical performance.
TL;DR: The ability of psychophysical observers and single cortical neurons to discriminate weak motion signals in a stochastic visual display is compared and psychophysical decisions in this task are likely to be based upon a relatively small number of neural signals.

Neural Basis of a Perceptual Decision in the Parietal Cortex (Area LIP) of the Rhesus Monkey
TL;DR: In this article, the posterior parietal cortex (area LIP) of two rhesus monkeys were recorded while they discriminated the direction of motion in random-dot visual stimuli and reported their direction judgment by making an eye movement to the appropriate target.

TL;DR: The results indicate that neural activity in MT contributes selectively to the perception of motion.

Properties of concentrically organized X and Y ganglion cells of macaque retina.
TL;DR: The results show that the X/Y dichotomy of ganglion cells is present in the retina of macaques and indicate that thedegree of the linearity of spatial summation of incoming cone signals to the cells is related to the degree of cone specificity of spectral inputs to the receptive-field mechanisms.

Composition of geniculostriate input ot superior colliculus of the rhesus monkey
TL;DR: The results suggest that the indirect visual pathway to the superior colliculus via cortex is activated selectively by the broad-band system, which is relayed through magnocellular LGN, which does not appear to have a corticotectal input sufficient to drive collicular cells independently.

TL;DR: The purpose in this study was to investigate in the behaving monkey the binocular cortical mechanisms that might underlie the ability to recognize the relative position and motion of objects in three‐dimensional space.
