Ever since Hubel and Wiesel described orientation selectivity in the visual cortex, the
question of how precise selectivity emerges has been marked by considerable debate …

In the cerebral cortex, local circuits consist of tens of thousands of neurons, each of which
makes thousands of synaptic connections. Perhaps the biggest impediment to …

Visual processing starts at the retina of the eye, and signals are then transferred primarily to
the visual cortex and the tectum. In the retina, multiple neural networks encode different …

Neurons in visual cortex are linked by an extensive network of lateral connections. To study
the effect of these connections on neural responses, we recorded spikes and local field …

Studying the laminar pattern of neural activity is crucial for understanding the processing of
neural signals in the cerebral cortex. We measured neural population activity [multiunit spike …

Visual cortex shows smooth retinotopic organization on the macroscopic scale, but it is
unknown how receptive fields are organized at the level of neighboring neurons. This …

The primary visual cortex contains a detailed map of the visual scene, which is represented
according to multiple stimulus dimensions including spatial location, ocular dominance and …

Circuits in the visual cortex integrate the information derived from separate ON (light-
responsive) and OFF (dark-responsive) pathways to construct orderly columnar …

Implantable neural devices that record neurons in various states, including static states, light
activities such as walking, and vigorous activities such as running, offer opportunities for …

Retinal ganglion cells that respond selectively to a dark spot on a brighter background (OFF
cells) have smaller dendritic fields than their ON counterparts and are more numerous. OFF …
