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

Individual Differences in the Alignment of Structural and Functional Markers of the V5/MT Complex in Primates
I Large,Holly Bridge,Bashir Ahmed,Stuart Clare,James Kolasinski,Wilfred W. Lam,Karla L. Miller,Tim B. Dyrby,Andrew Parker,Smith Jet.,G Daubney,Jerome Sallet,Andrew H. Bell,Andrew H. Bell,Kristine Krug +14 more
TL;DR: Variation in area identification for hMT+ based on structural and functional markers reflects individual differences in human regional brain architecture, and this work investigates the functionally homologous human motion complex (hMT+) using high-resolution in vivo imaging.

Computational aspects of motion perception in natural and artificial vision systems.
TL;DR: A computational scheme for motion perception in artificial and natural vision systems is described, motivated by a mathematical analysis in which first-order spatial properties of optical flow are shown to be salient features for the computation and analysis of visual motion.

Frontal Eye Field Neurons Assess Visual Stability Across Saccades
Trinity B. Crapse,Marc A. Sommer +1 more
TL;DR: The results indicate that FEF neurons evaluate visual stability during saccades and may be general purpose detectors of transaccadic visual change.

Can spatial and temporal motion integration compensate for deficits in local motion mechanisms
Lucia M. Vaina,Norberto M Gryzwacz,Pairash Saiviroonporn,Pairash Saiviroonporn,Marjorie LeMay,Don C. Bienfang,Alan Cowey +6 more
TL;DR: The motion perception of a patient, AMG, who had a lesion in the left occipital lobe centered on visual areas V3 and V3A, with involvement of underlying white matter is studied, indicating that she had a specific impairment of the computation of local but not global motion and that she could not integrate motion information across different spatial scales.

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.
