When Blindsight is 20 20

Blindsight is a condition where individuals can respond to visual stimuli without conscious awareness. It was first observed in a monkey named Helen and later in human patients like DB and TN. Despite damage to the V1 region of the brain, these individuals could still navigate and respond to visual cues. Scientists propose that other brain regions, such as the amygdala and hMT plus, may process visual information subconsciously. This phenomenon raises questions about the nature of consciousness and suggests that much of our brain's work occurs without our awareness.
