“Normally, contextual processes in the brain help us to focus on what’s relevant and stop our brains being overwhelmed with information. This process seems to be less effective in the schizophrenic brain, possibly due to insufficient inhibition–that is, the process by which cells in the brain switch each other off,” Dakin observes. The mechanism has more to do with vision than with cognition, such as attention span, the researchers report.
