'''Molecular Layer''' is the outermost layer of the [[Cerebellar cortex]], which is a part of the [[Cerebellum]]. It is primarily composed of two types of cells: [[Stellate cells]] and [[Basket cells]].

== Structure ==

The Molecular Layer is the most superficial layer of the cerebellar cortex. It is located between the [[Purkinje cell]] layer and the surface of the cerebellum. This layer is characterized by a relatively low density of cells, with the majority of the space being occupied by the dendritic trees of Purkinje cells.

The two main types of cells found in the Molecular Layer are stellate cells and basket cells. Both of these cell types are inhibitory interneurons, meaning they reduce the activity of other neurons.

=== Stellate Cells ===

[[Stellate cells]] are small, star-shaped interneurons. They receive excitatory input from the parallel fibers of [[Granule cells]], and provide inhibitory output to the dendritic trees of Purkinje cells.

=== Basket Cells ===

[[Basket cells]] are another type of interneuron found in the Molecular Layer. They are named for the basket-like appearance of their axons as they wrap around the cell bodies of Purkinje cells. Like stellate cells, basket cells receive excitatory input from the parallel fibers of granule cells. However, their inhibitory output is directed towards the cell bodies and initial segments of the axons of Purkinje cells.

== Function ==

The Molecular Layer plays a crucial role in the processing of sensory and motor information in the cerebellum. The inhibitory interneurons in this layer help to fine-tune the output of the cerebellar cortex by modulating the activity of Purkinje cells.
