In our study we presented functional and immuno-histochemical evidence for the presence of presynaptic N -methyl-D-aspartate receptors (pre-NMDARs) at parallel fi ber – Purkinje cell (PF-PC) synapses in the adult cerebellum. As in young rodents, pre-NMDARs are required to induce PF-PC synaptic plasticity (2). Using cell-speci fi c deletion of NMDARs in granule cells (GCs) or PCs, we demonstrated that only GC NMDARs are robustly involved in PF-PC synaptic plasticity and vesti-buloocular re fl ex (VOR) adaptation. Our data contradict those by Piochon et al. (3),
