  • Title: [Electrophysiologic study of the central projections of the ampullae of Lorenzini in the skate].

    Abstract:
    A large portion of the central nervous system of the skate Raja radiata was examined for responses related to single electroreceptor organs (ampullae of Lorenzini) or their groups. It was shown that electroreceptors project to the anterior lateral lobes of the medulla, caudal portion of the auricles and the mesencephalon. A topographic segregation of electroreceptors (to the anterior lateral lobes) and mechanical lateral afferents (to the posterior lateral lobes) was found. Unit receptive fields in the anterior lateral lobe showed no absolute somatotopic organization of electroreceptive input. Three main types of mesencephalic responses were found: ipsilateral, contralateral and both ipsi- and contralateral.
