ADHD medication amplifies brain response to grammatically ambiguous sentences, study finds

In a neuroimaging study published in PNAS, a team of researchers led by the Max Planck Institute for Psycholinguistics in Nijmegen recorded the brain activity of healthy adults during sentence comprehension after raising catecholamine levels with stimulant medication (methylphenidate). Higher catecholamine levels led to stronger recruitment of cognitive resources during processing of grammatically ambiguous sentences, showing how neurochemical systems may shape language processing.
