(2) that branch throughout the molecular cell layer (6) to the cerebellar surface.

Thin axons (not shown) leave the base of the Purkinje cells, pass through the
granular cell layer (4), become myelinated, and enter the white matter (5, 11).

The molecular cell layer (6) contains basket cells (1) with unmyelinated
axons that course horizontally. Descending collaterals of more deeply placed
basket cells (1) arborize around the Purkinje cells (3, 7). Axons of the granule

cells (9) in the granular cell layer (4) extend into the molecular layer (6) and also
course horizontally as unmyelinated axons.

The granular cell layer (4) contains small granule cells (9) with dark-staining
nuclei and little cytoplasm and larger Golgi type II cells (8) with vesicular

nuclei and more cytoplasm. Throughout the granular layer are small, irregularly
dispersed, clear spaces called the glomeruli (10) that contain only synaptic
complexes.
