UNIT STUDY OF THE TRIGEMINAL PROJECTIONS IN THE RETICULAR FORMATION OF THE MEDULLA OBLONGATA IN THE CAT

Guy Lamarche, J. M. Pierre Langlois, Maurice Héon

Abstract

The projections of the trigeminal nerve in the bulbar reticular formation of the cat have been investigated by recording unit activity after physiological stimulation of the face, in 50 "encéphales isolés" preparations. No somatotopical arrangement was found. The units susceptible to trigeminal afferents are widespread in the reticular formation of the medulla and are responsive to large areas of stimulation, mostly bilaterally symmetrical.
