Stellate

Overview

(adapted from: http://www.scholarpedia.org/article/Cerebellum#Neuronal_types):

Basket and Stellate cells: Are interneurons present in the molecular layer. They are both inhibitory (GABAergic) on to Purkinje cells. Their axons run in the same direction as the dendrites of the Purkinje cells are electrically coupled and receive both climbing fiber collaterals as well as parallel fibers originating in the granule layer.

Gap junctions and synapses between stellate cells

From: [RieublandS+2-2014]

By recording from multiple molecular layer interneurons in the cerebellar cortex, we reveal specific, nonrandom connectivity patterns in both GABAergic chemical and electrical interneuron networks.

Chemical connections exhibit a preference for transitive patterns, such as feedforward triplet motifs. This structured connectivity is supported by a characteristic spatial organization: transitivity of chemical connectivity is directed vertically in the sagittal plane, and electrical synapses appear strictly confined to the sagittal plane.
