Visual cortex: A cat's-eye view of the visual system
Optical imaging data show that the cat's visual cortex contains patches of cells that respond to low spatial and high temporal frequencies; outside the patches, cells respond to high spatial and low temporal frequencies. The results suggest a possible anatomical substrate for psychophysically defined spatial frequency channels.
متن کاملThe eye and visual nervous system: anatomy, physiology and toxicology.
The eyes are at risk to environmental injury by direct exposure to airborne pollutants, to splash injury from chemicals and to exposure via the circulatory system to numerous drugs and bloodborne toxins. In addition, drugs or toxins can destroy vision by damaging the visual nervous system. This review describes the anatomy and physiology of the eye and visual nervous system and includes a discu...
متن کاملImaging the visual system: from the eye to the brain.
Imaging technologies have revolutionized the study of human anatomy and physiology. Nowhere is this more evident than in the vision sciences, where imaging has provided unprecedented insights into the structure and function of the entire visual pathway in vivo. Ocular and retinal imaging techniques such as optical coherence tomography (OCT) have become established clinical tools, providing high...
متن کاملDynamics of Eye-Position Signals in the Dorsal Visual System
BACKGROUND Many visual areas of the primate brain contain signals related to the current position of the eyes in the orbit. These cortical eye-position signals are thought to underlie the transformation of retinal input-which changes with every eye movement-into a stable representation of visual space. For this coding scheme to work, such signals would need to be updated fast enough to keep up ...
متن کاملEye movement-invariant representations in the human visual system
During natural vision, humans make frequent eye movements but perceive a stable visual world. It is therefore likely that the human visual system contains representations of the visual world that are invariant to eye movements. Here we present an experiment designed to identify visual areas that might contain eye-movement-invariant representations. We used functional MRI to record brain activit...
