Purkinje neurons are found in

Purkinje cell, large neuron with many branching extensions that is found in the cortex of the cerebellum of the brain and that plays a fundamental role in controlling motor movement. Most Purkinje cells release a neurotransmitter called GABA (gamma-aminobutyric acid), which exerts inhibitory actions on certain neurons and thereby reduces the transmission of nerve impulses. These inhibitory functions enable Purkinje cells to regulate and coordinate motor movements.
