Endogenous modulation of human visual cortex activity improves perception at twilight

Visual perception depends on light—which changes according to time of day—but the accompanying neural changes are unknown. Here, authors use fMRI to describe the brain dynamics underlying visual perception and find that sensory areas change their activity to compensate for lower light at dawn and du...

Sumario:Visual perception depends on light—which changes according to time of day—but the accompanying neural changes are unknown. Here, authors use fMRI to describe the brain dynamics underlying visual perception and find that sensory areas change their activity to compensate for lower light at dawn and dusk.
