HIST10014 Lecture Notes - Lecture 11: Visual Cortex, Optic Disc, Peripheral Nervous System
Document Summary
Notes - neural correlates of attention and consciousness. Withdrawal from some things to deal e ectively with another. E ects of covert allocation of attention on visual perception. One can concentrate attention on the sensation from a particular part of our peripheral nervous system and at the same time exclude attention from all other parts. This is because this is important for our survival. Perception of the world is in uenced by attention and processing. Perception of the world is dependant on signals from the eye being processed in the particular part of the brain (primary visual cortex) Conscious visual signals comes from in the retina (eye) then goes to the thalamus (brain) Occurs following unilateral damage restricted to the primary visual cortex. Test how well they react to visual stimulation. May occur due to occipital lesion etc optic disc = chance elsewhere in the blind region = above chance.
