Human area Prostriata is a small, unstudied portion of the visual brain set deep in the calcarine sulcus, next to V1. A recent neuroimaging study in humans indicates that this area is specialized to respond to rapidly moving stimuli in the far periphery, consistent with single-unit responses ...
Knowledge about the visual system's functional anatomy has expanded tremendously in the past decade through the use ofbrain imagingtechniques.Optical imagingof the upper layers of thecerebral cortexin nonhuman primates, using activity-dependent changes in reflectance, can be used to study structure on ...
Microglia is distributed in the whole brain and is activated by stress. In order to confirm the regional stress reaction, we investigated lba-1-immunoreactivity (IR) as an activated microglia marker in the right thalamus and visual cortex, which contained the atrophic sites in this VBM analysis....
In primates, single-neuron correlates of category selectivity have been found in many cortical regions. In areas such as prefrontal cortex, lateral intraparietal cortex, posterior inferotemporal cortex and the frontal eye fields, substantial populations of category-selective neurons were observed following...
近期,电子科技大学生命学院脑器交互研究团队在《中国神经再生研究(英文版)》(Neural Regeneration Research)上发表了题为“Morphological disruption and visual tuning alterations in the primary visual cortex in glaucoma (DBA/2J) mice”研究论文。通过对青光眼小鼠(DBA/2J)和年龄匹配的正常小鼠(C57BL/6J)V1神经...
of visual experience and then allowing those mice to sleep, neurons in the cortex fired more when seeing that stimuli again. But the lab also showed the brain needs sleep in order to make cortical changes. If mice were deprived of sleep after the experience, no changes in the cortex ...
Seeing with the visual cortex Abstract A short analysis of the input-output organization of the primary visual cortical areas in the cat and monkey is followed by a description of the salient microelectrophysiological properties of retino-geniculo-cortical system neurons....
provides more than half of the input from the eyes to the visual cortex of the brain. When you look at a scene an arm's length away, the fovea subtends a field only about the size of your thumbnail. Your eyes undergo rapid movements to direct the fovea to various parts of the scene...
Sensory cortices can be affected by stimuli of multiple modalities and are thus increasingly thought to be multisensory. For instance, primary visual cortex (V1) is influenced not only by images but also by sounds. Here we show that the activity evoked b
In subject area: Engineering The human visual cortex includes the primary visual cortex (V1, also known as the striate cortex) and extrastriate cortex (V2, V3, V4, V5, etc.). From: Intelligence Science, 2021 About this pageSet alert ...
