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.

X and Y cells in the lateral geniculate nucleus of macaque monkeys.

TL;DR: It is proposed that the magnocellular layers of the macaque monkey's l.g.n. may be homologous to the A and A1 layer of the cat's l.'s l.n., and the great difference in their properties suggests that they have different functions in vision.

Columnar organization of directionally selective cells in visual area MT of the macaque.
TL;DR: There was a systematic relationship between penetration angle and rate of change of preferred axis of motion, indicating that cells with a similar direction of motion preference are arranged in vertical columns and cells with opposite direction preferences are located in adjacent columns within a single axis ofmotion column.

Uniformity and diversity of structure and function in rhesus monkey prestriate visual cortex.
TL;DR: It is argued that despite its uniformity in cytoarchitectural appearance and in ocular interaction patterns, there is a functional division of labour within the prestriate cortex.

Functional specificity of lateral geniculate nucleus laminae of the rhesus monkey
TL;DR: This study investigated the functional specificity of the lateral geniculate mucleus (LGN) of the rhesus monkey using microelectrode-recording techniques and found blue-selective cells are found predominantly in the ventral pair of parvocellular layers.
