Coherent oscillatory activity in monkey area v4 predicts successful allocation of attention.
Attention serves to select objects from often complex scenes for enhanced processing and perception. In particular, the perception of shape depends critically on attention for integrating the various parts of the selected object into a coherent representation of object shape. To study whether oscillatory neuronal synchrony may serve as a mechanism of attention in shape perception, we introduced...
متن کاملSpatial Attention Decorrelates Intrinsic Activity Fluctuations in Macaque Area V4
Attention typically amplifies neuronal responses evoked by task-relevant stimuli while attenuating responses to task-irrelevant distracters. In this context, visual distracters constitute an external source of noise that is diminished to improve attended signal quality. Activity that is internal to the cortex itself, stimulus-independent ongoing correlated fluctuations in firing, might also act...
متن کاملSpatial attention effects in macaque area V4.
Focal visual attention typically produces enhanced perceptual processing at the psychological level and relatively stronger neural responses at the physiological level. A longstanding mechanistic question is whether these attentional effects pertain specifically to the attended (target) object or to the region of space it occupies. We show here that attentional response enhancement in macaque a...
متن کاملArea V4 in Cebus monkey: extent and visuotopic organization.
We used electrophysiological mapping and myeloarchitectural criteria in order to define the location, extent and visual topography of the fourth visual area (V4) in anesthetized and paralyzed Cebus monkey. Based on these criteria, the borders of V4 with surrounding areas were defined both on the dorsal and ventral cortical surfaces. In addition, to better visualize the visuotopic organization a...
متن کاملIntrinsic lattice connections of macaque monkey visual cortical area V4.
We made focal iontophoretic as well as larger pressure injections (n = 30; 19 used for most analyses) of the tracer biocytin in visual area V4 of six macaque monkeys. The resulting transported label enabled mapping of intrinsic inter- and intralaminar connections within the region. We found that pyramidal neurons of layers 2 and 3 make extensive lateral projections within area V4, with oval or ...
