Humans can learn to intentionally control their brain states based on information about their own electrocortical activity. Using an operant conditioning technique, twelve healthy volunteers were trained to shift their slow cortical potentials recorded from left-hemispheric language cortices in the positive versus negative direction. After training, six subjects who achieved reliable control of left-hemispheric brain responses showed substantial modification of word processing. During conditioned negative shifts of cortical potentials (activation condition), responses to words were substantially speeded, whereas lexical decisions were slower during positive shifts of slow cortical potentials (inhibition condition). No comparable difference was seen in trained participants who failed to achieve control over slow cortical potentials. Additional data suggest that the effect was not related to perception, attention, or motor processes. Thus, operant conditioning can produce focal cortical activity dynamics and thereby modify specific higher cortical processes such as access to words. This finding may open new perspectives on neuropsychological rehabilitation based on operant conditioning of brain responses.
