The number of parallel fibre-Purkinje dendrite synapses. A morphometric evaluation

Summary

Quantitative parameters concerning synapses were studied in the cerebellar molecular layer of 4 cats using ultrastructural morphometric methods. The number of parallel fibre-Purkinje dendrite synapses was estimated to be about 200,000.
