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.

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.

A selective impairment of motion perception following lesions of the middle temporal visual area (MT)
William T. Newsome,EB Pare +1 more
TL;DR: The results indicate that neural activity in MT contributes selectively to the perception of motion.

Visual areas in the temporal cortex of the macaque
Robert Desimone,Charles G. Gross +1 more
TL;DR: Visual receptive fields and responsiveness of neurons to somesthetic and auditory stimuli were studied in the inferior temporal cortex and adjacent regions of immobilized macaques and showed no indication of any visuotopic organization within area TE.

Identification, classification and anatomical segregation of cells with X‐like and Y‐like properties in the lateral geniculate nucleus of old‐world primates.
TL;DR: Two classes of cells are anatomically segregated within the primate lateral geniculate nucleus: X‐like and Y‐like, which receive their excitatory input from retinal cells with slowly conducting axons and these most probably include the tonic ganglion cells described by Gouras.

Quantitative studies of single-cell properties in monkey striate cortex. I. Spatiotemporal organization of receptive fields
TL;DR: The properties of single cells in striate cortex of the rhesus monkey, representing the visual field 2 degrees -5 degrees from the fovea, were examined quantitatively with stationary and moving stimuli and showed differences between S-type and CX-type cells.

A representation of the visual field in the caudal third of the middle tempral gyrus of the owl monkey (Aotus trivirgatus).

TL;DR: In 7 experiments the visuotopic organization of the caudal third of the middle temporal gyrus was explored and a complete representation of the contralateral half of the visual field was revealed.

Parallel visual pathways: a review.
TL;DR: The aims of this paper are to examine the properties that characterize the neurons of the different classes and to understand what mechanisms might underly the differences; to trace the major central projection of theDifferent cell types and to try to understand their significance for seeing.
