Human's Animal

Man is totally blind, successfully navigates obstacles using vision (scientists think)— watch

apparent total absence of a striate cortex, the visual processing region

his brain was otherwise healthy, as were his eyes

no evidence that the patient was navigating by echolocation, the way that bats do

(so it wasn't auditory space perception)

the same African doctor had emotional blindsight

when presented with images of fearful faces,
he cringed subconsciously
even though he could not consciously see the faces
