As a first step in localizing the neuronal substrate of the learned category association, 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 fie...
6.1.1.3 Visual cortex Neurons in the LGN project to striate cortex (also known as primary visual cortex or V1), an anatomically distinctive cortical region in the occipital lobe, at the back of the brain. The cortex as a whole is a large, thin (∼2 mm) sheet containing several clearly...
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
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...
This study systematically identified two distinct defensive behaviors-sustained rapid escape (T1) and rapid habituation (T2). T1 involves superior colliculus (SC)/insular cortex-ventral tegmental area (VTA)-basolateral amygdala (BLA)...
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 ...

Although attention is known to increase the gain of visuocortical responses, its underlying neural computations remain unclear. Here, we use fMRI to test the hypothesis that a neural population’s ability to be modulated by attention is dependent on divi
How much of the structure of the human mind and brain is already specified at birth, and how much arises from experience? In this article, we consider the test case of extrastriate visual cortex, where a highly systematic functional organization is present in virtually every normal adult, includ...
