Anatomical terms of neuroanatomy

In neuroscience, stellate cells are any neuron that have a star-like shape formed by dendritic processes radiating from the cell body.

The three most common stellate cells are the inhibitory interneurons found within the molecular layer of the cerebellum, excitatory spiny stellate cells and inhibitory aspiny stellate interneurons. Cerebellar stellate cells synapse onto the dendritic arbors of Purkinje cells.[1] Cortical spiny stellate cells are found in layer IVC of the V1 region in the visual cortex.[2] They receive excitatory synaptic fibres from the thalamus and process feed forward excitation to 2/3 layer of V1 visual cortex to pyramidal cells. Cortical spiny stellate cells have a 'regular' firing pattern. Stellate cells are chromophobes, that is cells that does not stain readily, and thus appears relatively pale under the microscope.
