Prior object-knowledge sharpens properties of early visual feature-detectors

C Teufel, SC Dakin, PC Fletcher - Scientific reports, 2018 - nature.com
Early stages of visual processing are carried out by neural circuits activated by simple and
specific features, such as the orientation of an edge. A fundamental question in human …

[PDF][PDF] Conscious awareness of flicker in humans involves frontal and parietal cortex

D Carmel, N Lavie, G Rees - Current biology, 2006 - cell.com
Even when confined to the same spatial location, flickering and steady light evoke very
different conscious experiences because of their distinct temporal patterns. The neural basis …

Interobject grouping facilitates visual awareness

T Stein, D Kaiser, MV Peelen - Journal of Vision, 2015 - jov.arvojournals.org
In organizing perception, the human visual system takes advantage of regularities in the

Visual awareness is limited by the representational architecture of the visual system

MA Cohen, K Nakayama, T Konkle, M Stantić… - Journal of Cognitive …, 2015 - direct.mit.edu
Visual perception and awareness have strict limitations. We suggest that one source of
these limitations is the representational architecture of the visual system. Under this view …

Scene segmentation in early visual cortex during suppression of ventral stream regions

PR Grassi, N Zaretskaya, A Bartels - Neuroimage, 2017 - Elsevier
A growing body of literature suggests that feedback modulation of early visual processing is
