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

The complementary brain: unifying brain dynamics and modularity.
TL;DR: This article presents one alternative to the computer analogy that suggests brains are organized into independent modules and evidence is reviewed that brains are in fact organized into parallel processing streams with complementary properties.

How Is a Sensory Map Read Out? Effects of Microstimulation in Visual Area MT on Saccades and Smooth Pursuit Eye Movements
TL;DR: The pattern of alterations suggests that micro Stimulation can introduce an additional velocity signal into MT and that the pursuit and saccadic systems usually compute a vector average of the visually evoked and microstimulation-induced velocity signals.

Velocity sensitivity and direction selectivity of neurons in areas V1 and V2 of the monkey: influence of eccentricity.
TL;DR: One hundred and forty two neurons in V1 and V2 were quantitatively tested using a multihistogram technique in paralyzed and anesthetized macaque monkeys to assess changes in velocity sensitivity and direction selectivity with eccentricity.

The how and why of what went where in apparent motion: Modeling solutions to the motion correspondence problem.
TL;DR: A model that is capable of maintaining the identities of individuated elements as they move is described, and it solves a particular problem of underdetermination, the motion correspondence problem, by simultaneously applying 3 constraints: the nearest neighbor principle, the relative velocity principle, and the element integrity principle.

A model of self-motion estimation within primate extrastriate visual cortex.
John A. Perrone,Leland S. Stone +1 more
TL;DR: A template-based model of self-motion estimation which uses direction- and speed-tuned input sensors similar to neurons in area MT of primate visual cortex is refined to deal with the gaze-stabilization case and extended to extract heading and relative depth simultaneously.

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.
