Abstract
Two major systems are postulated to form the substrate for behavior. System I, associated with the reticular formation, is a response organization and execution mechanism. System II, associated with limbic-midbrain structures, is a stimulus-processing, attentional mechanism. The relation between these two systems is reciprocally inhibitory. By virtue of this reciprocity, stimulus processing leads to response selection. Response execution leads to selective attention. The extrapyramidal system, a phylogenetically old system, is viewed as having properties of both System I and System II, the mode being indicated by the activity of hippocampus.
