The Location of Primary Visual CortexSize, The
Visual cortex The human primaryvisual cortex(V1) is located in the mesial aspect of theoccipital lobewhere the superior and inferior banks of thecalcarine fissurereceive input signals from the parietal and temporaloptic radiations, respectively. A well-defined topographic map of the contralateral homo...
we exploited the fact that neurons in several areas of the visual cortex have well-defined, small receptive fields18,29. After mice had learned categorizing stimuli at a specific position in their visual field (26° azimuth), we proceeded with repeated sessions in which the stimulus position ...
In human adults, the cortex shows a systematic spatial and functional organization. Responses in visual cortex are driven by high-level, behaviourally relevant categories, including human faces, bodies, objects and natural scenes, both within circumscribed, highly selective regions1,2,3,4, and in ...
They were required to fixate on a small spot at the center of the monitor and distinguish whether two gratings presented one after the other with delays up to 1.5s in a specific visual field location were similar or not. It was found that such learning fails to transfer readily to other ...
In appropriate conditions, the apparent motion is indistinguishable from real motion: The observer experiences a luminous object traversing a continuous path from one stimulus location to the other through intervening positions where no physical stimuli exist. The phenomenon has been extensively investigated...
The size, location, distribution, and spatial orientation of the chandelier cell of the human visual cortex are described for the first time. The rapid Golgi method has been utilized to study the structural features of these inhibitory interneurons. The human chandelier cell is a small stellate in...
Changes in stimulus location (macular, perimacular, peripheral, upper-field, lower-field) caused systematic, highly significant changes in response locale within visual cortex. Discrete extrastriate visual responses were also observed. 展开 关键词: Simple Lie groups Controllability Invariant vector fields ...

The present study investigated how spatial working memory recruits early visual cortex. Participants were required to maintain a location in working memory while changes in blood oxygen level dependent (BOLD) signals were measured during the retention interval in which no visual stimulation was present....
