Bipolar neuron
Bipolar neuron: a nerve cell with one axon and one dendrite extending from opposite poles of the soma; rare sensory neurons of the retina, olfactory epithelium, and inner-ear ganglia.
Hippocampal pyramidal neuron
Hippocampal pyramidal neuron (CA pyramidal cell): glutamatergic principal neuron of hippocampal fields CA3, CA2, CA1 and subiculum; receives ~30,000 CA3 synapses in CA1, fires at ~1.4 Hz, and shows marked within-type heterogeneity.
Pyramidal cell
Pyramidal cell (pyramidal neuron): excitatory projection neuron of the cerebral cortex and hippocampus with pyramid-shaped soma, apical dendrite toward the pial surface, spiny dendrites, and a base-originating axon; the most common cortical neuron.
Stellate neuron
Stellate neuron (Cell Ontology CL:0000122, stellate cell): a neuron with star-shaped radiating dendrites. Distinct populations exist in cerebellar molecular layer (GABAergic), neocortical layer 4 (excitatory spiny stellate), and entorhinal cortex layer II (grid-cell related).
Unipolar neuron
Unipolar neuron (pseudounipolar neuron): a neuron with one process from the soma, typical of PNS sensory neurons in dorsal root and cranial nerve ganglia; develops from bipolar embryonic neurons, with axons up to 1 m or more.
