The spooky phenomenon that allows some blind people to navigate around objects has been pinned down to connections in the thalamus.

its authentic..its from 'new scientist' site..this can happen..patient's face is blurred,just to maintain confidentiality...vision is function of the occipital cortex...so in focal occipital lobe damage seen in some stroke, vision apparatus may be intact(retina and optic nerve are intact)...there is still transmission of information to brain and this way patient may subconsciously know this...because of the processing thats going on at lower levels of the brain(thalamus)...just the perception of vision will not be there because its the function of occipital lobe...
