A CORTICO-BULBO-RETICULAR PATHWAY FROM AREA 4-s

Abstract
By strychninizing the cortex and recording the electrical activity of the brain stem of the monkey, a pathway has been found to arise from area 4-S and to diverge from the cortico-spinal tract in the pons to reach the bulbar reticular formation. From its known physiologic properties this cortico-bulbo-reticular pathway is an extra-pyramidal system mediating relaxation.
