Fig. 3From: Differential synapse density between Purkinje cell dendritic spine and parallel fiber varicosity in the rat cerebellum among the phylogenic lobulesTransmission electron microscopy image of synapse and estimation of synapse density. This shows Purkinje cell dendritic spine synapse of molecular layer in cerebellum. Used transmission electron microscopy. a Indicate is synapse of molecular layer in cerebellum (arrows). × 60,000 Bar = 1 μm. b Histogram of synaptic density in the molecular layerBack to article page
