Retinotopic visual areas (top) and regions of increased neural activity during spatial attention (bottom) mapped onto flattened cortical representations of the left (LH) and right hemispheres (RH ...

Neuronal shifts with attention inside the receptive field. To investigate the influence of attention on receptive fields, we recorded from 78 neurons in cortical area MT of two macaque monkeys.

The major areas associated with visual attention are labeled here, ... From the LGN, information is relayed to the visual cortex (V1–V5) and then to higher cortical areas.

Verghese says this is likely because the attention required in reading involves a lot more areas of the brain than the primary visual cortex, for example the word-forming area of the brain. Her ...

Focal attention is an important tool of ... "our contribution shows how the previous vision of canonical circuits within visual cortical areas is not immediately linked to the idea of parallel ...

Their results identified three cortical networks that were successively activated from the back to the front of the brain when the participants' attention was captured by visual stimuli, as if ...

For example, if there's a flow of visual information, VSA neurons send information outside of the cortex to other parts of the brain. But if it's dark, these sub-cortical areas still need to know ...

According to the standard model of visual processing, all visual information from the retina must first pass through the primary visual cortex (V1) in the back of the brain, which extracts simple ...

The researchers found that when the animals were paying attention to an area within their field of view, ... Aug. 27, 2021 — New research reveals that neurons in the visual cortex ...

For this study, the researchers worked with primates and analyzed cortical electrophysiological signals at multiple depths recorded simultaneously in V1 and V4 brain areas.
