Blindsight vs. Blindside — What's the Difference?

Blindsight is the ability of people who are cortically blind due to lesions in their striate cortex, also known as the primary visual cortex or V1, to respond to visual stimuli that they do not consciously see. The term was coined by Lawrence Weiskrantz and his colleagues in a paper published in Brain in 1974.
