Drawing of Purkinje cells (A) and<unk> s (B) from pigeon cerebellum by Santiago Ramón y Cajal, 1899. Instituto Santiago Ramón y Cajal, Madrid, Spain. The name<unk>  has been used for a number of different types of neurons whose only common feature is that they all have very small cell bodies.<unk> s are found within the<unk> r layer of the cerebellum, the dentate gyrus of the hippocampus, the superficial layer of the dorsal cochlear nucleus, the olfactory bulb, and the cerebral cortex. Cerebellar<unk> s account for the majority of neurons in the human brain. These<unk> s receive excitatory input from mossy fibers originating from pontine nuclei. Cerebellar<unk> s project up through the Purkinje layer into the molecular layer where they branch out into parallel fibers that spread through Purkinje cell dendritic arbors. These parallel fibers form thousands of excitatory<unk> –Purkinje-cell synapses onto the intermediate and distal dendrites of Purkinje cells using glutamate as a neurotransmitter. Layer 4<unk> s of the cerebral cortex receive inputs from the thalamus and send projections to supragranular layers 2–3, but also to infragranular layers of the cerebral cortex.
