In [[neuroscience]], '''stellate cells''' are neurons with several dendrites radiating from the cell body giving them a star shaped appearance. The three most common stellate cells are the [[Inhibitory postsynaptic potential | inhibitory]] [[interneurons]] found within the [[Cerebellum#Molecular_Layer|molecular layer]] of the [[cerebellum]], [[Excitatory postsynaptic potential | excitatory]] spiny stellate [[interneurons]] and [[Inhibitory postsynaptic potential | inhibitory]] aspiny stellate [[interneurons]].
Cerebellar stellate cells synapse onto the [[dendrite | dendritic]] arbors of [[Purkinje cell]]s.
[[Image:Pyramsdal-and-Spiny-stellate-cell.JPG|thumb|left|Golgi stained cortical neurons A) Layer II/IIIpyramidal cell B) layer IV spiny stellate cell]]Cortical spiny stellate cells are found in layer IV. They receive excitatory synaptic fibres from the thalamus and process feed forward excitation to layer IV pyramidal cells. Cortical Spiny Stellate cells have a 'regular' firing pattern.
