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

Associative learning of shape as a cue to appearance: a new demonstration of cue recruitment.
TL;DR: This work demonstrates recruitment of a new cue, object shape, for the appearance of rotating 3D objects, established by interleaving ambiguous and disambiguated instances of two shapes, cubes and spheres, at the same retinal location.

Neural and phenotypic representation under the free-energy principle
Maxwell J. D. Ramstead,Casper Hesp,Alexander Tschantz,Ryan Smith,Axel Constant,Axel Constant,Axel Constant,Karl J. Friston +7 more
TL;DR: A generalizable model of the representational capacities of living creatures based on the free-energy principle is developed and numerical demonstrations for the neuronal packet hypothesis (that Markov blankets encode stimulus features) are provided.

Mécanismes et bases cérébrales du traitement des fréquences spatiales lors de la catégorisation de scènes visuelles
TL;DR: In this article, a travers deux etudes comportementales, nous avons tout d'abord montre qu'une analyse '' coarse-to-fine'' est plus avantageuse for la categorisation rapide de scenes, and que, independamment de la valeur de contraste de luminance associee aux differentes frequences spatiales.

Revisiting the functional significance of binocular cues for perceiving motion-in-depth
TL;DR: The authors address this paradox and show that spatial and interocular integration mechanisms, distinct from the extraction of motion-in-depth, drive suppression.
Visual Perception Deficits Associated with the Magnocellular Pathway in Schizophrenia
Jejoong Kim,Sohee Park +1 more
TL;DR: There is evidence suggesting that impaired perceptual processing may interact with or mediate cognitive deficits, although degraded perceptual processing is not necessarily associated with cognitive deficits.

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.
