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

Interactions between dorsal and ventral streams for controlling skilled grasp
TL;DR: This paper argues that the interactions between dorsal and ventral streams are important for controlling complex object-oriented hand movements, especially skilled grasp, and hypothesised that the dorsal stream needs to retrieve detailed information about object identity when the object properties require complex fine-tuning of the grasp.
Journal ArticleDOI
A model of visually-guided smooth pursuit eye movements based on behavioral observations.
TL;DR: A negative-feedback system that uses three parallel visual motion pathways to drive pursuit reproduces the average eye velocity evoked by steps of target velocity in monkeys and humans and accounts for the variation among individual responses and subjects.
Journal ArticleDOI
Centrifugal directional bias in the middle temporal visual area (MT) of the macaque.
TL;DR: A marked anisotropy favoring directions that are oriented away from the center of gaze is found among neurons with peripherally located receptive fields that corresponds well to the biased distribution of motions characteristic of optic flow fields, which are generated by displacement of the visual world during forward locomotion.

Cells in monkey STS responsive to articulated body motions and consequent static posture: a case of implied motion?
Tjeerd Jellema,David I. Perrett +1 more
TL;DR: It is proposed that the neural representations in STSa for actual biological motion may also extend to biological motion implied from static postures that could play a role in producing the activity in the medial temporal/medial superior temporal (V5(MT)/MST) areas reported in fMRI studies when subjects view still photographs of people in action.

How does the cerebral cortex work? Development, learning, attention, and 3-D vision by laminar circuits of visual cortex.
TL;DR: The identified cortical mechanisms promise to generalize to explain how other perceptual and cognitive processes work, and begin to unify three fields: infant cortical development, adult cortical neurophysiology and anatomy, and adult visual perception.

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.
