Cortical circuits work through the generation of coordinated, large-scale activity patterns. In
sensory systems, the onset of a discrete stimulus usually evokes a temporally organized …

Neurons in early visual cortical areas not only represent incoming visual information but are
also engaged by higher level cognitive processes, including attention, working memory …

Cognitive functions rely on the coordinated activity of neurons in many brain regions, but the
interactions between cortical areas are not yet well understood. Here we investigated …

The location of short-term memory in mammalian neocortex remains elusive. Here we show
that distinct neocortical areas maintain short-term memory depending on behavioral …

The traditional view on visual processing emphasizes a hierarchy: local line segments are
first linked into global contours, which in turn are assembled into more complex forms …

An essential part of visual perception is the grouping of local elements (such as edges and
lines) into coherent shapes. Previous studies have shown that this grouping process …

Studies in biological vision have always been a great source of inspiration for design of
computer vision algorithms. In the past, several successful methods were designed with …

Perceptual grouping of line segments into object contours has been thought to be mediated,
in part, by long-range horizontal connectivity intrinsic to the primary visual cortex (V1), with a …

Association areas in neocortex encode novel stimulus-outcome relationships, but the
principles of their engagement during task learning remain elusive. Using chronic wide-field …

Segregation of images into figures and background is fundamental for visual perception.
Cortical neurons respond more strongly to figural image elements than to background …
