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

Functional consequences of an integration of motion and stereopsis in area mt of monkey extrastriate visual cortex
TL;DR: A network model is presented that effectively uses the disparity sensitivity of MT-like neurons for the reduction of noise in optic flow fields and reproduce the recent psychophysical finding that the robustness of the human optic flow processing system is improved by stereoscopic depth information, but that the use of this information depends on the structure of the visual environment.

The role of V5 (hMT+) in visually guided hand movements: an fMRI study
Celia Oreja-Guevara,Raimund Kleiser,Walter Paulus,Wolfgang Kruse,R. J. Seitz,Klaus-Peter Hoffmann +5 more
TL;DR: Investigation of the functional role of V5 (hMT+) in the control of visually guided hand movements and to identify the corresponding cortex activation implicated in the visuomotor tasks using functional magnetic resonance imaging found it has a pivotal role during the visual control of forelimb movements.

A Cell Model for the Detection of Local Image Motion on the Magnocellular Pathway of the Visual Cortex
Susumu Kawakami,Hiroaki Okamoto +1 more
TL;DR: Five types of cell on the magnocellular pathway of the visual cortex constitute a function hierarchy for detecting local image motion and reflect the response to various stimuli in actual cells, and explain Adelson and Movshon's two-stage hypothesis neurophysiologically.

Deficits and recovery of first- and second-order motion perception in patients with unilateral cortical lesions
TL;DR: One of the patients, who was retested several times during a 27‐month postlesional period, showed complete recovery for first‐ and second‐order motion direction discrimination, as well as for the detection of speed differences.

Study of Subjective Quality and Objective Blind Quality Prediction of Stereoscopic Videos

TL;DR: The proposed algorithm, which is completely blind (requiring no reference videos or training on subjective scores) is called the Motion and Disparity-based 3D video quality evaluator (MoDi3D), which delivers competitive performance over a wide variety of datasets, including the IRCCYN dataset, the WaterlooIVC Phase I datasets, the LFOVIA dataset, and the proposed LFOVIAS3DPh2 S3D video dataset.

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.
