The cerebellar cortex contains which pair of layers?

The cerebellar cortex has three distinct layers: the outer molecular layer, the middle Purkinje cell layer, and the inner granular (granule) layer. Purkinje cells reside in the Purkinje layer as large neuronal bodies, while granule cells populate the granular layer as many tiny neurons. The molecular layer is mostly neuropil containing Purkinje dendrites and granule cell axons (parallel fibers) but few cell bodies. The best choice emphasizes two key, clearly defined layers with their own neuronal populations: the granule (granular) layer and the Purkinje cell layer. This pairing reflects the core laminar organization of the cerebellar cortex, where granule cells provide input that synapses onto Purkinje cells, whose axons then project to the deep cerebellar nuclei.
