The primary visual cortex (V1) is probably the best characterized area of primate cortex, but whether this region contributes directly to conscious visual experience is controversial. Early neurophysiological and neuroimaging studies found that visual awareness was best correlated with neural activity in ...
It has been hypothesized that neural activities in the primary visual cortex (V1) represent a saliency map of the visual field to exogenously guide attention. This hypothesis has so far provided only qualitative predictions and their confirmations. We report this hypothesis' first quantitative ...
6.1.1.3Visual cortex Neurons in theLGNproject tostriate cortex(also known asprimaryvisual cortexorV1), an anatomically distinctive cortical region in the occipitallobe, at the back of the brain. The cortex as a whole is a large, thin (∼2 mm) sheet containing several clearly defined layers...
1. Introduction In the non-dualistic approach to consciousness, visual awareness is mediated by the activity of nerve cells. The question that is specifically addressed in this paper, is to what extent the nerve cells in visual cortical area V1, or primary visual cortex, contribute to visual ...
Here we tested whether human primary visual cortex (V1) is engaged in dynamic prediction by preplaying anticipated visual events. We characterized neural activity in the primary visual cortex at both high spatial and temporal resolution, by combining ultra-fast functional magnetic resonance imaging (...
The mouse primary visual cortex (V1) has emerged as a classical system to study neural circuit mechanisms underlying visual function and plasticity. A variety of efferent-afferent neuronal connections exists within the V1 and between the V1 and higher visual cortical areas or thalamic nuclei, indi...
V1, primary visual cortex; V2, secondary visual cortex, V3, third visual cortex. Full size image Specific receptive fields of the detected V1 neurons The monkeys were trained to perform a fixation task with a brief presentation of a peripheral visual stimulus (Fig. 3a). During this task, ...
The final stage of the network consists of edge detectors of various orienations arranged in a feature map, corresponding to the primary visual cortex, or V1. The lateral geniculate nucleus is modeled as a preprocessing stage. Excitatory forward and inhibitory backward connections exist between the...
In this paper, we offer an explanation for how selectivity for orientation could be produced by a model with circuitry that is based on the anatomy of V1 cortex. It is a network model of layer 4Calpha in macaque primary visual cortex (area V1). The model consists of a large number of...
