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

Anatomy and Physiology of Macaque Visual Cortical Areas V1, V2, and V5/MT: Bases for Biologically Realistic Models.
TL;DR: An overview of over 350 published studies of these three areas in the genus Macaca, whose visual system provides the closest model for human vision, concludes that V5 neurons are distinct from neurons in other areas for their higher direction selectivity, higher contrast sensitivity, higher temporal frequency tuning, and wider SF bandwidth.

Direction-specific fMRI adaptation reveals the visual cortical network underlying the “Rotating Snakes” illusion
TL;DR: The "Rotating Snakes" figure elicits a clear sense of anomalous motion in stationary repetitive patterns and provides evidence for the role of front-end motion detectors, which has been assumed in proposed models of the illusion.
Journal ArticleDOI
Responses of MST neurons to plaid stimuli
TL;DR: The relationship between MST and MT is qualitatively similar to that between MT and V1, as repeated application of basic motion mechanisms leads to novel selectivities at each stage along the pathway.

Playing the electric light orchestra--how electrical stimulation of visual cortex elucidates the neural basis of perception
Nela Cicmil,Kristine Krug +1 more
TL;DR: The function and organization of visual cortex is reconsidered according to results obtained from stimulation techniques, with a special emphasis on electrical stimulation of small groups of cells in awake subjects who can report their visual experience.

Perceptual learning beyond retinotopic reference frame
TL;DR: By manipulating subjects’ gaze direction to control spatial and retinal locations of stimuli independently, it is found that the improvement with training in motion-direction discrimination of two successively displayed stimuli was restricted to the relative spatial position of the stimuli but independent of their absolute locations in head- and world-centered frame.

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.
