BG cell processes covering PC synapses. A, Electron micrographs showing BG processes (false-colored in pink) at PF–PC synapses, marked with asterisks, in the upper third of the molecular layer. Images from mutant and control mice are indistinguishable (age 9–10 months). Scale bar, 1 μm. B, PF–PC synapse density in the upper part of the molecular layer was unaltered in mutant mice at the indicated ages. C, PC synapses are normally covered by BG processes in mutant mice at both time points. D, Calculated mitochondrial density of BG processes was unaltered in mutant mice compared with controls. Data shown as mean ± SEM. n.s., Not significant.
