Functional properties of neurons in middle temporal visual area of the macaque monkey. I. Selectivity for stimulus direction, speed, and orientation
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:Â
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.

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.

Discharge Characteristics of Single Units in Superior Colliculus of the Alert Rhesus Monkey
P H Schiller,F Koerner +1 more
TL;DR: The aim of the present study was to investigate the discharge characteristics of single units in the superior colliculus of the alert, unanesthe tized monkey and to assess both the visual receptivefield characteristics of units and the possible relation of unit discharges to eye movement.
Journal ArticleDOI
Representation of central visual fields in prestriate cortex of monkey.
TL;DR: The many disagreements over the anatomy, extent and functions of the prestriate cortex in the monkey have been reviewed at length and it is sufficient to point out that the disagreements have not only been interdisciplinary but also intradisciplinary.

The functional properties of the light-sensitive neurons of the posterior parietal cortex studied in waking monkeys: foveal sparing and opponent vector organization.
BC Motter,VB Mountcastle +1 more
TL;DR: It is proposed that a dynamic central neural process associated with the acts of fixation and visual attention suppresses responses to foveal stimuli.

Visual topography of striate projection zone (MT) in posterior superior temporal sulcus of the macaque.
Ricardo Gattass,Charles G. Gross +1 more
TL;DR: The results further support the suggestion that MT in the macaque is homologous to visual area MT in New World primates and is similar to striate cortex in being a first-order transformation of the visual field.

Saccadic and smooth pursuit eye movements in the monkey
TL;DR: A training technique is described which conditions the animals to follow a large variety of target trajectories and is described as well as a method to measure voluntary eye movements in the chronic, unanaesthetized monkey.
