These cells play significant roles in various brain functions, including inhibition in the cerebellum and excitation in the cortex, and are involved in synaptic plasticity and neurovascular coupling.

These cells can be immunohistochemically labeled with glutamic acid decarboxylase (GAD) due to their GABAergic activity, and they occasionally colocalize with neuropeptides.

The characteristics of these EPSCs depend on the pattern and frequency of presynaptic activity, influencing the extent and duration of inhibition within the cerebellar cortex.

[9] Synapses between parallel fibers and stellate cells exhibit plasticity, allowing for long-term changes in synaptic efficacy.

Electrophysiological stimulation of single stellate cells is sufficient to release nitric oxide (NO) and induce dilation of blood vessels.
