How the brain generates visual percepts is a central problem in neuroscience. We propose
a detailed neural model of how lateral geniculate nuclei and the interblob cortical stream …

Because of its distinctive architecture, connections, and functions, primary visual cortex, area
17 or V1 of primates, can be easily identified in most mammals (Kaas, 1987). V1 (also …

Traditional views of visual processing suggest that early visual neurons in areas V1 and V2
are static spatiotemporal filters that extract local features from a visual scene. The extracted …

Simple cells in the primary visual cortex often appear to compute a weighted sum of the light
intensity distribution of the visual stimuli that fall on their receptive fields. A linear model of …

WE report here the use of positron emission tomography (PET) to reveal that the primary
visual cortex is activated when subjects close their eyes and visualize objects. The size of …

Most fMRI studies are based on the detection of a positive BOLD response (PBR). Here, we
demonstrate and characterize a robust sustained negative BOLD response (NBR) in the …

In the classical feed-forward, modular view of visual processing, the primary visual cortex
(area V1) is a module that serves to extract local features such as edges and bars …

NEURONS in the primary visual cortex (VI) respond in well defined ways to stimuli within
their classical receptive field, but these responses can be modified by stimuli overlying the …

We investigated the spatial organization of surround suppression in primate primary visual
cortex (V1). We utilized drifting stimuli, configured to extend either from within the classical …

Iso-orientation surround suppression is a powerful form of visual contextual modulation in
which a stimulus of the preferred orientation of a neuron placed outside the classical …
