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

Juggling revisited - a voxel based morphometry study with expert jugglers
Peter Gerber,Lara Schlaffke,Stefanie Heba,Mark W. Greenlee,Thomas Schultz,Tobias Schmidt-Wilcke +5 more
TL;DR: This study provides evidence that expert jugglers show increased gray matter density in brain regions involved in visual motion perception and eye-hand coordination, i.e. brain areas that have previously been shown to undergo dynamic changes in terms of gray matter increases in subjects learning a basic three-ball cascade.

Dynamics of directional selectivity in MT receptive field centre and surround
János A. Perge,Bart G. Borghuis,Roger J. E. Bours,Martin J. M. Lankheet,Richard J. A. van Wezel +4 more
TL;DR: The results show that surround input and biphasic behaviour reflect two different mechanisms, which make MT cells specifically sensitive to motion contrast in space and time.

Retinotopic organization of ferret suprasylvian cortex.
TL;DR: The retinotopic organization of striate and several extrastriate areas of ferret cortex has been established and the representation of the visual field on the Suprasylvian visual area (Ssy), which is distinct from adjoining areas in anatomical architecture, is described.

The computational study of vision
Ellen C. Hildreth,Shimon Ullman +1 more
TL;DR: The computational approach to the study of vision inquires directly into the sort of information processing needed to extract important information from the changing visual image, such as the three-dimensional structure and movement of objects in the scene, or the color and texture of object surfaces.

Computational modelling of optic flow selectivity in MSTd neurons.
TL;DR: Network analysis with neurophysiological stimuli identified a majority of hidden units whose position invariance and motion selectivity were consistent with MSTd responses to the visual motion components of optic flow stimuli reported by Duffy and Wurtz and Graziano et al.

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.
