Anatomical terms of neuroanatomy

The pedunculopontine nucleus (PPN) or pedunculopontine tegmental nucleus (PPT or PPTg) is a collection of neurons located in the upper pons in the brainstem. It is involved in voluntary movements, arousal, and provides sensory feedback to the cerebral cortex and one of the main components of the ascending reticular activating system. It is a potential target for deep brain stimulation treatment for Parkinson's disease. It was first described in 1909 by Louis Jacobsohn-Lask, a German neuroanatomist.
