SOME blind people have the remarkable ability to navigate physical obstacles without consciously perceiving them (see video, above). It now looks like they have their (LGN) 鈥� part of the thalamus in the middle of the brain 鈥� to thank for this 鈥渂lindsight鈥�.
That鈥檚 according to a team at the US National Institute of Mental 91色情片 in Bethesda, Maryland. They used macaques in which parts of the primary visual cortex had been destroyed.
The monkeys鈥� eye-focusing movements, coupled with scans of brain activity, revealed that they were 鈥渟eeing鈥� images shown in the 鈥渂lind鈥� part of their visual field, but only if their LGN was intact (Nature, ).
