Visual cortex: cartography, connectivity, and concurrent processing

James J. Knierim, David C. Van Essen
1992 Current Opinion in Neurobiology  
The mammalian visual cortex contains a complex mosaic of areas that are richly connected with one another.  ...  Recent progress has advanced our understanding of both macroscopic and microscopic aspects of cortical organization, and of information flow within and between functionally specialized processing streams  ...  One possible anatomical substrate for these surround effects is the long-range horizontal connectivity intrinsic to each cortical area.  ...

Disparity Context Processing in the Primate Brain: And If the Question was Both ?What? and ?When??

Benoit R. Cottereau
2011 Frontiers in Human Neuroscience  
In monkeys, a recent study (Verhoef et al., 2011) used functional connectivity to demonstrate that areas IT and AIP are communicating during 3D-shape perception.  ...  These results are different from those obtained in macaque ventral area V4 (Umeda et al., 2007) .  ...

Intrinsic lattice connections of macaque monkey visual cortical area V4

T Yoshioka, JB Levitt, JS Lund
1992 Journal of Neuroscience  
In parallel studies we have been comparing biocytin-labeled intrinsic connectivity patterns in macaque areas V 1, V2, and V4.  ...  They found that the suppressive surround of a V4 cell is tuned to the same wavelength as the receptive field itself; that is, maximal suppression occurred when the stimulus wavelength in the surround matched  ...

Selective Tuning for Contrast in Macaque Area V4

I. Sani, E. Santandrea, A. Golzar, M. C. Morrone, L. Chelazzi
2013 Journal of Neuroscience

Spectral properties of V4 neurons in the macaque

SJ Schein, R Desimone
1990 Journal of Neuroscience  
In this respect, V4 cells in the macaque resemble cells in area DL of the owl monkey (Baker et al., 198 l) , a region that may be homologous with V4 in the macaque.  ...  Area V4 has been the subject of more interest-and more controversy-than probably any visual area in extrastriate cortex of the macaque.  ...

Visual attention as a multilevel selection process

S. KASTNER, M. A. PINSK
2004 Cognitive, Affective, & Behavioral Neuroscience  
Second, areas at intermediate cortical-processing levels, such as V4 and TEO, appear to be important sites at which attention filters out unwanted information by means of receptive field mechanisms.  ...  that are transmitted via feedback connections to the visual system.  ...  The reduced suppressive interactions in V4 and TEO during directed attention were similar in magnitude to the suppressive interactions obtained in area V2 in the unattended condition.  ...
