User: What is blindsight? What are the neurological origins or theories? What areas of the brain are effected?

Weegy: Blindsight is a phenomenon in which people who are perceptually blind in a certain area of their visual field demonstrate some response to visual stimuli. origins, however, stem from animal research and neuroanatomy. [ The primate retina, including that of humans, sends its major neural output (after a relay in the thalamus) to the visual cortex ("V1", "striate cortex"). When the striate cortex is removed or blocked in monkeys, the animals can still carry out visual discriminations although their capacity changes in certain ways. That they can still do so is perhaps not surprising because the output from the eye also reaches a number of other brain targets lying in the midbrain and thalamus that remain intact even when V1 is entirely removed . Blindsight is caused by injury to the part of the brain responsible for vision the occipital lobe. ]

Blindsight is a condition where individuals with certain types of brain damage have visual abilities despite being consciously blind. The neurological origins are linked to damage in the primary visual cortex, but other visual pathways and subcortical structures may contribute.
