Abstract

Median nerve somatosensory evoked potentials (SEP) were recorded in 7 Cynomolgus monkeys, before and after the administration of N-Methyl 1,4 Phenyl 1,2,3,6 tetrahydropiridine (MPTP), a neurotoxin which induces a parkinsonian syndrome in primates. Following MPTP administration, the amplitude of the negative component recorded at 15 ms over the frontal derivations (N15) decreased by 70% or more. This amplitude reduction was not modified by administration of dopamine precursors. These findings shed light on recent findings in human parkinsonian patients.
