This contribution reviews the anatomy of the pedunculopontine and peripeduncular nuclei. Given the reported findings of Mazzone et al. in NeuroReport, the authors postulate that the peripeduncular nucleus might be of previously unexpected clinical relevance. © 2007 Lippincott Williams & Wilkins, Inc.
