Researchers believe they may have found a way to stimulate learning within the visual brain, as its been discovered that the neural learning section appears to be separate from conscious visual processing.

A study from the University of Minnesota's College of Liberal Arts and College of Science and Engineering was done to determine how well participants could identify faint patterns of bars on a computer screen. The objects would continue to decrease in faintness. The study found that over a period of 30 days, participants were able to train themselves to recognize fainter images.

"We discovered that learning actually increased the strength of the EEG signal," said lead author Stephen Engel. "Critically, the learning was visible in the initial EEG response that arose after a subject saw one of these patterns. Even a tiny fraction of a second after a pattern was flashed, subjects showed bigger responses in their brain."

Some researchers believe that these findings could be used as a way to help those who suffer from visual problems by accelerating the development of how the brain trains itself to visually learn.
