Their morphological characteristics express that they represent bundles of Purkinje fibers. A severe fluorescence after incubation in antisera up to the intermediate filament protein skeleton is also backing this suggestion [5].
Neurons from the contralateral vestibular nuclei and Purkinje fibers from the cerebellum are believed to exert their inhibitory effects via this GABAergic system.
The electrical impulses split here into the right and left bundles that travel through each side of the ventricles and wind up in the Purkinje Fibers which cause the ventricle to contract.
The intrinsic rate of perinodal fibers of the atrioventricular (AV) junction are the first line of protection, and when they fail, the Purkinje fibers of the ventricular system provide the last option for ensuring tissue perfusion.
