  • Title: Effect of levo-acetylcarnitine on P300-like potentials of the normal monkey.
    Author: Onofrj M, Ghilardi MF, Faricelli A, Bodis-Wollner I, Calvani M.
    Journal: Drugs Exp Clin Res; 1987; 13(7):407-15. PubMed ID: 3652929.
    Abstract:
    Endogenous components of evoked potentials resembling P300 in human beings were sequentially studied in four cynomolgus monkeys (Macaca fascicularis using an auditory "oddball" paradigm, after classical conditioning training. When robust P300-like signals were obtained, each animal underwent further recording sessions in which a placebo, L-carnitine or L-acetylcarnitine (LAC) was injected. Only LAC induced an amplitude increment of P300 waves in all the animals and a latency decrement in two animals. Furthermore a transient effect with amplitude reduction on the primary cortical auditory evoked potentials (AEP) both to rare and frequent tones was also recorded in all the animals. This effect resembled the AEP amplitude reduction induced by physostigmine administration. The findings suggest an effect of LAC on normal processes accompanying cognition.
