has soma location stellate neuron stellate interneuron cerebellar stellate cell cerebellar SC A GABAergic interneuron that is located in the molecular layer of the cerebellum. This cell receives excitatory inputs primarily from parallel fibers and plays a crucial role in feed-forward inhibition by suppressing the activity of Purkinje cells and modulating the output of the cerebellar cortex. The stellate cell is part of the local circuitry that contributes to the fine-tuning of motor coordination and a regulator of cerebellar blood flow via neurovascular coupling. molecular layer interneuron molecular layer of cerebellar cortex
