Functional near-infrared spectroscopy (fNIRS) can be performed using a portable emitter and detector placed on the scalp near a region of interest in the brain. By emitting and sensing light at ...

A new study questions the longstanding view that the visual system is divided into two pathways, one for object-recognition and the other for spatial tasks. Using computational vision models, ...

CAMBRIDGE, MA -- Incoming information from the retina is channeled into two pathways in the brain’s visual system: one that’s responsible for processing color and fine spatial detail, and another that ...

Researchers discover a new visual pathway that bypasses the primary visual cortex in mice, a structure previously considered essential to all visual processing. The newly discovered pathway (red).

One of the most powerful forms of depth perception capitalizes on the small relative displacements, or binocular disparities, in the images projected onto each eye. The brain employs these disparities ...

When visual information enters the brain, it travels through two pathways that process different aspects of the input. For decades, scientists have hypothesized that one of these pathways, the ventral ...

Research led by Peking University, China, has discovered a single type of retinal photoreceptor cell in Drosophila (fruit fly) is involved in both visual perception and circadian photoentrainment by ...
