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

Origin and Function of Tuning Diversity in Macaque Visual Cortex
Robbe L. T. Goris,Robbe L. T. Goris,Eero P. Simoncelli,Eero P. Simoncelli,J. Anthony Movshon +4 more
TL;DR: A diverse population of neurons provides better overall discrimination capabilities for natural images than any homogeneous population, because neurons with different selectivities are adapted to different stimulus configurations.

Processing of kinetically defined boundaries in the cortical motion area MT of the macaque monkey
TL;DR: It is concluded that cells in area MT appear to respond to the motion vector over their classical receptive field (CRF) only and were unable to code the orientation of the kinetic boundary.
Journal ArticleDOI
Neural Dynamics of Motion Processing and Speed Discrimination
TL;DR: A neural network model of visual motion perception and speed discrimination that shows how a distributed population code of speed tuning, that realizes a size-speed correlation, can be derived from the simplest mechanisms whereby activations of multiple spatially short-range filters of different size are transformed into speed-turned cell responses.

Facilitation of Smooth Pursuit Initiation by Electrical Stimulation in the Supplementary Eye Fields
Marcus Missal,Stephen J. Heinen +1 more
TL;DR: The results are further evidence that the SEF plays a role in smooth pursuit in addition to its known role in saccade planning and suggest that this role may be to control the gain of smooth pursuit during initiation.

Induced deficits in speed perception by transcranial magnetic stimulation of human cortical areas V5/MT+ and V3A
TL;DR: The results suggest that, in addition to area V5/MT+, V3A plays an important role in a cortical network that underpins the perception of stimulus speed in the human brain.

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.
