physical source of peduncles?
[edit]I think I've seen that there's a pair of cerebellar peduncles from each of the midbrain, pons, & medula, making up the 6. Can anyone verify if that's true or not? And coincidentally, does the mid-brain connect directly to the thalamus and how (with what structure?) And the pair of cerebral peduncles come from the superior anterior aspect of the pons?UnderEducatedGeezer (talk) 20:31, 17 November 2016 (UTC)
direction, kinds of signals
[edit]I would like to add information about the kind of signals sent in the peduncles (directionality), but I don't have good citations for that information, nor do I know how to properly make the citations. I'd like to add to the lead:
Superior cerebellar peduncle ...(ADD): comprised mostly of efferent (motor) fibers. Middle cerebellar peduncles ...(ADD): (afferent, sensory) fibers. Inferior cerebellar peduncle ... (ADD): comprised of mostly afferent (sensory) fibers.
A citation I can find for middle cerebellar peduncle is: Jan Voogd, Tom J.H. Ruigrok, Pages 471-545, in The Human Nervous System (Third Edition), 2012, Edited by:Juergen K. Mai and George Paxinos. What I find there (online) says: Middle Cerebellar Peduncle The middle cerebellar peduncle, or the brachium pontis, enters the cerebellum fairly laterally. The middle peduncle is purely afferent. Its origin from the contralateral pontine nuclei was first demonstrated by Vejas (1885) in chronic experiments in the rabbit.
And for Inferior & Middle: The Nervous System (Second Edition) Author(s): Adina T. Michael-Titus, Patricia Revest and Peter Shortland. Which says, (from online): The inferior and middle cerebellar peduncles are predominantly input pathways, while the superior peduncle is the predominant output pathway from the deep cerebellar nuclei.UnderEducatedGeezer (talk)
