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:
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

Axis-of-motion affects direction discrimination, not speed discrimination
Nestor Matthews,Ning Qian +1 more
TL;DR: Whether direction discrimination and speed discrimination were differentially affected by changes in the axis-of-motion is investigated to distinguish between these possibilities and implies that the sensory response which constrains speed discrimination is at least partially independent from the sensory responses which constrain direction discrimination.

Functional properties of rotation-sensitive neurons in the posterior parietal association cortex of the monkey.
TL;DR: The continuous change of direction of movement was the most important cue for RS neurons to respond selectively to rotary movement in contrast to linear translational movement, and that these neurons were likely to discriminate the direction and orientation of the plane of rotation of the object in space.

The Role of the Lateral Intraparietal Area in (the Study of) Decision Making
TL;DR: The resulting sensorimotor-focused approach offers an account of LIP activity as a multiplexed amalgam of sensory, cognitive, and motor-related activity, with a complex and often indirect relationship to decision processes.

Cortical and subcortical afferents to the nucleus reticularis tegmenti pontis and basal pontine nuclei in the macaque monkey.
Roland A. Giolli,Kenneth M. Gregory,David A. Suzuki,Robert H. I. Blanks,Fausta Lui,Kathleen F. Betelak +5 more
TL;DR: The combined anterograde and retrograde labeling data indicated that visuo-motor cortico-pontine pathways arising from parietal cortices target only the basal pontine gray, whereas the NRTP, together with select pontine nuclei, is a recipient of afferents from frontal cortical areas.

Comparing Acceleration and Speed Tuning in Macaque MT: Physiology and Modeling
TL;DR: A model incorporating adaptation and a neuron's speed tuning that predicted the higher inferred speeds and lower spike rates for deceleration responses compared with acceleration responses did not predict acceleration-specific responses, in accordance with the lack of acceleration sensitivity in neurons.

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.
