Information Processing Strategies and Pathways in the Primate Visual System
The mammalian visual pathway is an amazingly complex and intricate system, capable of processing vast amounts of sensory information for use in the precise control of both immediate and long-term behavior. In many respects, the system is very well engineered for efficient extraction and encoding of information. To give just one example, it is well known that the spacing between photoreceptors i...

متن کاملCorticocortical and thalamocortical information flow in the primate visual system.
Visual cortex in primates contains a mosaic of several dozen visual areas that collectively occupy a large fraction of cerebral cortex (approximately 50% in the macaque; approximately 25% in humans). These areas are richly interconnected by hundreds of reciprocal corticocortical pathways that underlie an anatomically based hierarchy containing multiple processing streams. In addition, there is ...
متن کاملVisual Processing in the Primate Brain
Vision is the most widely studied and dominant sensory system in human and nonhuman primates. Of the total surface area of the cerebral cortex roughly 50% in macaque monkey, and 20 to 30% in human, is largely or exclusively involved in visual processing (Van Essen, 2004; Van Essen & Drury, 1997). Intensive study of vision in nonhuman primates, and particularly the macaque, has produced a detail...
متن کاملInformation processing during transient responses in the crayfish visual system
We analyzed sustaining fiber responses in the crayfish visual system to light pulses using information processing techniques. The light pulse stimuli elicited a transient and a steadystate component in the EPSP input and in the firing rate of the spike train output. The overall information transfer of the system was very low ( ̃ ), with a sharp increase during the transient portion of the respon...
