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

Unveiling the abstract format of mnemonic representations
Yu-Seok Kwak,Clayton E. Curtis +1 more
TL;DR: It is demonstrated that distinct visual stimuli are flexibly recoded into the same WM format in visual and parietal cortices when that representation is useful for memory-guided behavior.

A simple competitive account of some response properties of visual neurons in area MSTd
TL;DR: Simulation results obtained from this model show that the behaviors of the output nodes of the network resemble very closely the known responsive properties of the M STd neurons found neurophysiologically, such as the existence of three types of MSTd neurons that respond, respectively, to one, two, or three type of the input motion patterns with different position dependences.

A model using MT-like motion-opponent operators explains an illusory transformation in the optic flow field
TL;DR: A physiologically based model using motion-opponent operators to compute heading performs accurately for simulated observer translations and can be used to predict the perceptual shift of the focus of expansion for novel visual stimuli.

Distinct fMRI Responses to Self-Induced versus Stimulus Motion during Free Viewing in the Macaque.
TL;DR: In this paper, the authors measured fMRI activity in the brains of two macaques as they freely viewed >50 hours of naturalistic video footage depicting dynamic social interactions, and used eye movements obtained during scanning to estimate the level of reafferent retinal motion at each moment in time.

Spatiotemporal separability in the human cortical response to visual motion speed : a magnetoencephalography study
TL;DR: The results support the view that the human visual system has three sets of mechanisms tuned to spatial frequency, temporal frequency, and speed.

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.
