SUMMARY The brainstem course of the limb afferent component of the central tegmental fasciculus has been determined in both the cat and the phalanger, Trichosurus vulpecula , using evoked potentials. Unit records obtained from the reticular formation indicate that the ascending central tegmental fasciculus arises in large part from the level of the superior olives. The termination of the system is found mainly in n. parafascicularis of the posterior thalamus. Attention is drawn to the correspondence between the ascending central tegmental fasciculus and the reticular activating system (arousal system) of the medial brainstem.
