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

Tactile motion activates the human middle temporal/V5 (MT/V5) complex.
Matthew C. Hagen,Ove Franzén,Francis McGlone,Francis McGlone,Gregory K Essick,Christopher Dancer,Christopher Dancer,José V. Pardo,José V. Pardo +8 more
TL;DR: In this subject, tactile motion produced a significant increase in rCBF that directly overlapped a region activated by visual motion at the posterior continuance of the inferior temporal sulcus, consistent with the known location of hMT/V5.

Asymmetric Suppression Outside the Classical Receptive Field of the Visual Cortex
TL;DR: The spatial organization of surrounds of single-cell receptive fields in the primary visual cortex of anesthetized, paralyzed cats is examined to demonstrate that the surrounds are more specific than previously realized, and this specialization has implications for the processing of visual information in thePrimary visual cortex.

The kinetic occipital (KO) region in man: an fMRI study.
TL;DR: Functional magnetic resonance imaging is used to explore the properties of the kinetic occipital (KO) region, which previous position emission tomography studies have shown to be involved in the processing of kinetic boundaries.
Journal ArticleDOI
The occipitoparietal pathway of the macaque monkey: comparison of pyramidal cell morphology in layer III of functionally related cortical visual areas.
TL;DR: Observations, comparing dendritic fields of neurons in the homologous cortical layer at different levels of a physiologically defined 'stream', indicate changes in pyramidal cell morphology between functionally related areas.

The cortical connections of area V6: an occipito‐parietal network processing visual information
Claudio Galletti,Michela Gamberini,Dieter F. Kutz,Patrizia Fattori,Giuseppe Luppino,Massimo Matelli +5 more
TL;DR: It is suggested that V6 plays a pivotal role in the dorsal visual stream, by distributing the visual information coming from the occipital lobe to the sensorimotor areas of the parietal cortex.

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.
