Functional properties of neurons in middle temporal visual area of the macaque monkey. I. Selectivity for stimulus direction, speed, and orientation
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

Contribution of area MT to stereoscopic depth perception: choice-related response modulations reflect task strategy.
TL;DR: It is suggested that the recorded from middle temporal neurons approach provides a physiological means to explore how task strategies are implemented in the brain and is explained by the task strategy that monkeys learned during training.

Spatial summation in the receptive fields of MT neurons.
TL;DR: The spatial extent over which one stimulus would divide the response to another and found effective normalization from stimuli quite far removed from the RF center is found, which supports models under which normalization occurs both in MT and in earlier stages.

Contrast Dependence of Suppressive Influences in Cortical Area MT of Alert Macaque
TL;DR: The tuning of neurons in the middle temporal area of macaque visual cortex for moving stimuli of varying contrast is described, finding that, for some MT neurons, tuning curves for stimulus direction, speed, and size are shaped in part by suppressive influences that are present at high stimulus contrast but weak or nonexistent at low contrast.

Computing stereo disparity and motion with known binocular cell properties
TL;DR: A model for biological stereo vision based on known receptive field profiles of binocular cells in the visual cortex is proposed and the first demonstration that these cells could effectively solve random dot stereograms is provided.

Maps of Visual Space in Human Occipital Cortex Are Retinotopic, Not Spatiotopic
TL;DR: It is concluded that the early, visuotopically organized visual cortical areas in the human brain (like their counterparts in the monkey brain) represent stimuli in a retinotopic reference 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.
