| description | any structural anomaly of the population of large inhibitory GABAergic interneurons found in the cerebellar internal granule layer which act by altering the mossy fibre - granule cell synapse; the main synapse made by these cells is a synapse onto the mossy fibre - granule cell excitatory synapse in a glomerulus, which is composed of the mossy fibre terminal, granule cell dendrites, and golgi terminal and is enclosed by a glial coat |
