  • Title: Inhibition of inferior olivary transmission by mesencephalic stimulation in the cat.
    Author: Hesslow G.
    Journal: Neurosci Lett; 1986 Jan 02; 63(1):76-80. PubMed ID: 3005925.
    Abstract:
    Cerebellar climbing fiber responses (CFRs) evoked in anesthetized cats by stimulation of peripheral nerves, contralateral inferior olive and cerebellar white matter were investigated by recording unit activity and surface field responses in anterior lobe of cerebellar cortex. When nerve and olive stimulation was preceded at long intervals (greater than 35 ms) by weak electrical stimulation of an ipsilateral mesencephalic area close to the locus coeruleus and brachium conjunctivum, CFRs could be virtually abolished in the pars intermedia but not in the vermis. White-matter evoked CFRs were not affected; thus the site of the inhibition was the inferior olive.
