Functional maps arise in developing visual cortex as response selectivities become
organized into columnar patterns of population activity. Recent studies of developing …

Orientation columns exist in the primary visual cortex (V1) of cat and primates but not mouse.
Intriguingly, some recent studies reported the presence of orientation and direction columns …

The visual cortex represents stimuli through the activity of neuronal populations. We
measured the evolution of this activity in space and time by imaging voltage-sensitive dyes …

The computation represented by a sensory neuron's response to stimuli is constructed from
an array of physiological processes both belonging to that neuron and inherited from its …

In this, the post-genomic age, our knowledge of biological systems continues to expand and
progress. As the research becomes more focused, so too does the data. Genomic research …

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 …

In mammals, the perception of motion starts with direction-selective neurons in the visual
cortex. Despite numerous studies in monkey primary and second visual cortex (V1 and V2) …

Excitatory lateral connections within the primary visual cortex are thought to link neurons
with similar receptive field properties. Here we studied whether this rule can predict the …

Whether general principles can explain the layouts of cortical maps remains unresolved. In
primary visual cortex of ferret, the relationships between the maps of visual space and …

When presented with simple stimuli like bars and gratings, adjacent neurons in striate cortex
exhibit shared selectivity for multiple stimulus dimensions, such as orientation, direction, and …
