Functional properties of neurons in middle temporal visual area of the macaque monkey. I. Selectivity for stimulus direction, speed, and orientation
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

Temporal and spatial characteristics of the upper displacement limit for motion in random dots.
Ken Nakayama,Gerald H. Silverman +1 more
TL;DR: Increasing field size had the following effects: it increased Dmax, it decreased delta t (the processing time), it increased Vmax (the maximum velocity), and it increased the amount of sequential recruitment.

Optical Imaging Reveals the Functional Architecture of Neurons Processing Shape and Motion in Owl Monkey Area MT
TL;DR: The results suggest that area MT, like V1 and V2, has a rich and multidimensional functional organization, and that orientation, a shape variable, is one of these dimensions.
Journal ArticleDOI
Responses to auditory stimuli in macaque lateral intraparietal area. I. Effects of training.
TL;DR: Some LIP cells become active for auditory stimuli in a passive fixation task, once the animals have learned that these stimuli are important for oculomotor behavior.

TL;DR: Large-scale changes in resting state network interactions are identified that are a physiological signature of spatial neglect and may relate to its right hemisphere lateralization.

Microstimulation in visual area MT: effects of varying pulse amplitude and frequency
TL;DR: The behavioral effects of varying current amplitude, current frequency, and electrode position suggest that the effects of low-amplitude microstimulation depend upon direct activation of a well-localized population of neurons.

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.
