Dans les neurones du noyau rouge, il a ete demontre par l'enregistrement intracellulaire que les potentiels hyperpolarisants de longue duree sont produits par la stimulation de la region du noyau interpose et du cortex cerebelleux. En changeant le potentiel de membrane de la cellule, l'amplitude de l'hyperpolarisation diminue ou augmente parallelement avec celle du potentiel postsynaptique excitateur (EPSP). En consequence, l'hyperpolarisation ne provient pas du potentiel postsynaptique inhibiteur (IPSP), mais d'une reduction de l'effet tonique facilitateur exerce par le noyan interpose sur les neurones du noyau rouge («disfacilitation»).
