Peter Lakatos and Charlie Schroeder have conducted elegant work showing that the brain entrains its rhythms to attended sensory inputs. Here, Lakatos et al show that normal human subjects show increased rhythmic entrainment with increasing task demands, By contrast, schizophrenic patients are less able to match their brain rhythms to attended stimuli, even when the task is highly demanding.
