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

The Representation of Behavioral Choice for Motion in Human Visual Cortex
TL;DR: The results suggest that, even when selective responses to a given feature are distributed relatively broadly across the visual system, the conscious experience of that feature may be primarily based on activity within specialized cortical areas.
Journal ArticleDOI
Hierarchical processing of complex motion along the primate dorsal visual pathway
TL;DR: A unique, naturalistic motion stimulus was developed and used to probe the complex selectivity of MST neurons and it was found that this type of integration has the functional role of improving estimates of the 3D velocity of moving objects.
Journal ArticleDOI
Attention to speed of motion, speed discrimination, and task difficulty: an fMRI study.
TL;DR: Manipulating the difficulty of the speed discrimination task over a large range of the psychometric curve revealed that increasing difficulty linearly increases activity in right frontal regions, as well as in lateral occipital and dorsal parietal regions.
Journal ArticleDOI
Anisotropies in visual motion perception: a fresh look.
TL;DR: Investigation thresholds were invariant with direction of motion, but direction-discrimination thresholds were significantly higher for motion in oblique directions, even at low-coherence levels, which indicates that the oblique effect is relative to retinal coordinates.
Journal ArticleDOI
A model for encoding multiple object motions and self-motion in area MST of primate visual cortex.
TL;DR: A neurally constrained model based on the hypothesis that neurons in MST partially segment the motion fields generated by several independently moving objects is explored, consistent with recent studies indicating that MST cells primarily encode information concerning the relative three-dimensional motion between objects and the observer.

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.
