Document Summary

Parallel: each stream does its processing independently and simultaneously. Hierarchy: each stage in the stream does its processing before sending to the next stage thalamocortical pathway. Eye (retina) thalamus (lateral geniculate nucleus) cortex (primary visual cortex) Hierarchical: each successive stage does more advanced processing of info received from the preceding stage. Example: feature detection cells in the cortex. Eyes: blindness cortex - cortical blindness: loss of conscious vision following damage to visual cortex. Patient feels completely blind [their conscious vision is gone, but their unconscious vision is still functioning] He"s missing his primary visual cortex, and feels blind. When given a forced choice" situation, he feels like he"s guessing, however his performance suggests otherwise . Blindsight: how is it possible? it"s because there are other pathways operating in parallel to the thalamocortical pathway these pathways subconsciously guide our actions [gut instinct] secondary visual cortex.
