Essentials of Cerebellum and Cerebellar Disorders
Stellate cells are inhibitory GABAergic interneurons located in the molecular layer of the cerebellar cortex. Stellate cells receive excitatory glutamatergic inputs from parallel fibers (PF) and climbing fibers, as well as inhibitory GABAergic input from other stellate cells and Purkinje cell axon collaterals (Witter et al. Neuron 91:312–319, 2016). These inhibitory interneurons suppress the activity of Purkinje cells through feed-forward inhibition. A variety of mechanisms regulate GABA release at inhibitory synapses in the cerebellar cortex and consequently alter cerebellum-dependent motor and non-motor functions.
