It ‘can learn’ to see: Study shows perception of invisible stimuli improves with practice

The researchers showed subjects with normal vision of two forms, a square and a diamond, it was immediately followed by a mask. The subjects were asked to identify the shape they had seen. The first form is invisible to the subjects in the first test, but after 5 training sessions, subjects were better able to identify both the square and the diamond.. Such as cancer, vascular diseases such as atherosclerosis – the narrowing of the arteries – involves an overgrowth of cells and the invasion.D.

‘A question that had not been addressed until now was whether a feature of the human brain, namely its ability to produce consciousness, is also trainable,’ said Schwiedrzik. ‘Our results imply there is no fixed boundary between the things we see and the things that we do not perceive -. That this limit can be moved’

‘Our study suggests that it might in principle be possible to blind patients to recover some visual awareness, and therefore our results could open a site for a new line of research and potential treatments for patients with acquired cortical blindness ‘said Schwiedrzik.

The ability to train the brain to see deliberate could help blind people, whose primary visual cortex has been damaged by stroke or trauma. Blind patients can not consciously see, but at some level, their brains process their visual environment.

A study conducted by Harvard Medical School last year revealed that a patient could blind maneuver in a corridor full of obstacles, even if the subject could not really see.
