Anatomical terminology |
In neuroscience, stellate cells are neurons with several dendrites radiating from the cell body giving them a star shape. 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.[citation needed]
Cortical spiny stellate cells are found in layer IVC of the V1 region in the visual cortex. 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.[clarification needed]

- Cyclooxygenase-2 (COX-2) is involved in different liver diseases but little is known about the significance of COX-2 in the development and progression of non-alcoholic steatohepatitis (NASH). This study was designed to elucidate the role of COX-2 expression in hepatocytes in the pathogenesis of ste

- … Long-term depression (LTD), a type of synaptic plasticity, at excitatory parallel fiber–Purkinje cell synapses has been studied extensively as a primary cellular mechanism of motor learning. … On the other hand, at inhibitory synapses on a Purkinje cell, postsynaptic depolarization induces long-lasting potentiation of GABAergic synaptic transmission. … A Purkinje cell expresses both α- and β-CaMKII, and the latter has much higher affinity for Ca[2+]/calmodulin than the former. …
