Evidence of ancient evolutionary visual paths

Migrated topic.
it seems to me it shows that visual reception is not only made by the visual cortex. If the visual cortex interprets the more conscious intellectual information of vision, maybe the cerebellum or other parts of the brain associated with more instinctive and/or motor functions may get to interpret the visual stimulus independently.

very interesting
 
Yes very interesting.

The accompanying text says that the subject was unaware of doing anything exceptional and that he thought he had just walked down a straight corridor, but the video quite clearly shows him steppin arond things. He must have been aware of recieving something!!!
 
I think this is just a case of rudimentary echolocation. There are cues he can take from the sounds of his steps, how the echoes return to him from the walls and floor. Then of course there is the constant background noise or hum. Which you can tell when it is altered by a reasonable obstacle. I see no mention or "ears" or "hearing" and am dissapointed they did not rule out human echo location.

This is sort of the point of those long telescopic sticks for a blind man to carry making a *clack* *clack* sound, it can also be used if not on a subconscious level as a form of sharp "pings" (think naval submarine) to aid the mind in spatial awareness.
 
This is a well known phenomenon in neuroscience called blind site. It involves regions of the cortex other than V1. This behavior is not possible in individuals with damage to the retina thus ruling out the echo-location. For blind site to occur Input from the retina is still required, it is just that were as most of the input goes to the thalamus and then on to V1 some of this goes from the thalamus directly to motor processing regions and thus even though the individual does not have a conscious perception (V1 is believed to be required but not responsible) they can still react to the environment. It makes you wonder why are we even aware at all? Could we in fact be robots?

nice, as I thought

I dont know if you are familiar with gurdjieff, but he had some system about the workings of the human being as having (basically) 3 semi-independent centers, the motor, the emotional and the intellectual.

its interesting because for example in korsakov syndrome which happens with some alcoholics, a certain brain damage can cause a person to lose short term memory since a particular incidence, but remember everything before (like in the film memento). I forgot the term for this type of memory issue. Anyways so this particular case, a man had no memory of his father's death, which happened after the pathology showed up. Even though he had no memory, he still did not want to visit his dad for some reason he couldnt explain. It was as if his feelings knew it, but his intellect not.

This is all fascinating
 
Antereograde amnesia is what you are referring to. Meaning one can not form new memories since the time of the damage which is typically to the hippocampus. If all memory is lost like in alzhemimers it is referred to as retrograde amnesia. These patients can not remember anything about their lives.
