Neuroanatomy

• Layers of cerebellar cortex-

1. Molecular layer - Outermost layer  ; Contains Stellate cells , Basket cells 

2. Purkinje layer - Middle layer ; Contain Purkinje cells (Flask shaped cells)

3. Granular layer - Innermost layer ; Contain Granule cells , Golgi cells

" Cell bodies of Purkinje cells are located in Purkinje layer , Dendrites of Purkinje cells pass into molecular layer & Axons of Purkinje cells pass into granular layer from there to white matter and eventually forms synapse with deep cerebellar nuclei "

• Intrinsic neurons of cerebellar cortex - 

Stellate cells 

Basket cells 

Purkinje cells (Flask shaped cells) (Largest intrinsic neurons of cerebellum)

Granule cells 

 Golgi cells

All the intrinsic neurons of cerebellar cortex are inhibitory except Granule cells . The granule cells form the only excitatory neurons in cerebellar cortex

The only neurons of cerebellar cortex which can transmit efferent impulses (or) the only output neurons  from cerebellar cortex is inhibitory (GABAergic) from Purkinje cells to Deep cerebellar nuclei / intracerebellar nuclei 

Deep cerebellar nuclei -from Medial to lateral - Fastigial nuclei , Globose nuclei , Emboliform nuclei , Dentate nuclei .

• Neurotransmitters released :- 

1. GABA - Stellate cells , Basket cells , Purkinje cells , Golgi cells 

2. Glutamate - Granule cells
