The Reticular Core—1957

Abstract
The authors review extensive brain stem literature which has appeared since the last survey. "The whole seems to substitute for the older concept of centers (each with its apparent specificity), a newer dynamics stressing over-all integration, multi-modal activation of units, and behavioristic implications for functioning. The conceptual importance of the reticular core has increased until the cerebral cortex itself is in point of becoming a dependency. The older notion that the brain stem had only lower level properties is now less rigidly held; and, speculatively at least, its rostral part is said occasionally to concern itself with highest level integration. However, conflicting currents remain, resulting from ideological and methodological differences..." The subject is organized under these heads: (1) the anatomical substrate; (2) electrophysiological recording; (3) contributions to neuromuscular control; (4) immobilizing agents and anesthetics; (5) humorally induced effects and drugs; (6) sleep, loss of consciousness and behavioral implications.
