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

Factors affecting footsteps: contrast can change the apparent speed, amplitude and direction of motion.
TL;DR: It is shown that back and forth apparent motion appears smaller in amplitude at low contrasts, even on a spatially uniform (non-striped) surround, and this is a specific motion phenomenon, not a result of misjudging static position.

The development of global motion discrimination in school aged children.
TL;DR: The improvement in global motion perception is underpinned by a steady increase in the efficiency with which direction signals are pooled, suggesting that global motion pooling processes mature for longer and later than local motion processing.

What neurological patients tell us about the use of optic flow.
Lucia M. Vaina,Simon Rushton +1 more
TL;DR: This chapter reports data from several neurological patients, their psychophysical performance on optic flow tasks and observed co-occurring locomotor competencies, and suggests that the study of neurological patients may provide researchers with a critical test of the flow theory for locomotion.

The changing disparity energy model
Qiuyan Peng,Bertram E. Shi +1 more
TL;DR: The changing disparity energy model is proposed, a physiologically plausible model for neurons tuned to changing disparity that combines the disparity and motion energy models commonly used to model cortical neuron outputs and is consistent with psychophysical experiments indicating that stereomotion speed discrimination thresholds for dynamic random dot stereograms are higher than for randomdot stereograms.

Timing of V1/V2 and V5+ activations during coherent motion of dots: an MEG study.
Esther Alonso Prieto,Utako B. Barnikol,Ernesto Palmero Soler,Kevin Dolan,Guido Hesselmann,Hartmut Mohlberg,Katrin Amunts,Karl Zilles,Michael Niedeggen,Peter A. Tass +9 more
TL;DR: This study indicates that during visual motion analysis, V1/V2 and V5+ are activated repeatedly through forward and feedback connections and both contribute to m-VEFs M1 and M2.

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.
