Brain Training May Help The Blind-Sighted To See

Scientists at the Max Planck Institute for Brain Research have found that brain training may help people who are blind due to injury to the brain region responsible for vision, gain some vision.

Patients whose primary visual cortex has been damaged through a stroke or trauma cannot consciously see, but at some level their brains are still processing their visual environment. Through brain training, these patients may regain some conscious awareness of what their minds can see.

Caspar Schwiedrzik, the study leader said that the study “suggest that it might in principle be possible for blind-sight patients to recover some visual awareness”.

This might open a new line of research and potential treatments for patients with acquired cortical blindness.

The brain is continuously adapting and can be trained to see consciously what was consciously unseen previously.
