THE PROJECTIONS OF THE GRISEUM CENTRALE MESENCEPHALI, NUCLEUS DARKSCHEWITSCH AND NUCLEUS INTERSTITIALIS OF CAJAL ONTO THE NUCLEUS RAPHE MAGNUS AND ADJACENT RETICULAR FORMATION (NUCLEUS RETICULARIS GIGANTOCELLULARIS AND NUCLEUS RETICULARIS PONTIS C / 解剖学报

ABSTRACT

Neurons descending from the griseum centrale mesencephali, nucleus Darkschewitsch and nucleus interstitialis of Cajal to the nucleus raphe magnus and adjacent reticular formation (nucleus reticularis gigantocellularis and nucleus reticularis pontis caudalis) were identified in 9 adult cats with the retrograde HRP method. In the griseum centrale mesencephali, the labeled neurons were found bilaterally but slightly more ipsilaterally. In the nucleus Darkschewitscb and nucleus interstitialis of Cajal, the labeled neurons were consistently found in its rostral part ipsilateral to the injected side at the level of the posterior commissure. In addition, in 5 of the 9 cases, a few labeled neurons were observed in the nucleus raphe dorsalis.
