Layers of the cerebellar grey matter

Layers of differentiated neurons in the grey matter

The cerebellar cortex consists of three layers of differentiated neurons (Granule, Golgi, Purkinje, Basket and Stellate):

1. Molecular: Contains cell extensions and some interneurons (basket cells and stellate cells)

2. Purkinje: Contains Purkinje neurons, whose axons project to the deep nuclei and are the only exit route from the cortex

3. Granular: The most abundant layer in terms of cells. Among them are the granules cells, whose ascending axons branch out in a "T" shape, forming parallel fibres that synapse on the Purkinje

Cells within each layer of grey matter

• Basket cells

• Stellate cells

• Purkinje cells

• Granule cells

Afferent fibres within the cerebellar cortex

The cerebellar cortex receives three types of afferent fibers:

• Climbing fibers: Come from the inferior olivary nucleus

• Mossy fibers: Originate in the brainstem and spinal cord

• Beaded fibers/Monoaminergic varicose fibers: Form part of the monoaminergic modulatory.
