The Location of Primary Visual CortexSize, The
In a visual input containing many bars, one of them saliently different from all the other bars which are identical to each other, saliency at the singleton's location can be measured by the shortness of the reaction time in a visual search task to find the singleton. The hypothesis ...
Acquisition of new skills has the potential to disturb existing network function. To directly assess whether previously acquired cortical function is altered during learning, mice were trained in an abstract task in which selected activity patterns were
The second panel shows the receptive fields of the cells, and how they change with V1 location. The third panel shows more clearly the rotation of such fields with translation across V1. One also finds that cells with similar feature preferences tend to arrange themselves in vertical columns ...
The "where" pathway, also known as the dorsal pathway, is involved in spatial processing and guiding actions related to objects in the visual field. It begins from the primary visual cortex (V1) and extends into the parietal lobe. This pathway helps in determining the location of objects ...
初级视觉皮质2) primary visual cortex 初级视觉皮层 1. Purpose: To investigate the temporal characteristics of BOLD responses to brief visual stimulation of the human primary visual cortex (V1). 目的:探讨在短暂视觉刺激情况下 ,大脑初级视觉皮层 (V1)的血氧水平依赖 (BOLD)性响应的时间特性。
However, a role of the primary visual cortex in working memory has remained unnoticed in fMRI studies. Due to suppression of the overall activity, this location-specific memory signal may vanish by analyzing the enhancement of the more global responses. Therefore, in contrast with the delayed ...
The depth of layer 4 was determined from where the visual stimulus (flash) evoked a strong response in the current source density (CSD)28,29(Fig.S1). The unit location along the cortical depth was adjusted relative to layer 4 (depth 0 indicates the center of layer 4). The estimated ...
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 ...
Multisensory integration in the primary visual cortex (V1) of the monkey has not been established, apart from a clear influence of a non visual eye position signal on visual activity [35, 36]. However, auditory or visuo-auditory responses in area V1 are highly probable since we have ...
