Purkinje Cell Migration and Differentiation
Handbook of the Cerebellum and Cerebellar Disorders, 2021The Purkinje cell is the pivotal element of the cerebellar network, which integrates distinct extracerebellar inputs and generates the ultimate cortical output to be conveyed to the deep cerebellar nuclei. During development, the adult Purkinje cell phenotype is acquired through a complex sequence of ontogenetic processes, including migration from the ...

THE FINE STRUCTURE OF THE PURKINJE CELL [PDF]
Journal of Cell Biology, 1963 This paper describes the fine structure of the Purkinje cell of the rat cerebellum after fixation by perfusion with 1 per cent buffered osmium tetroxide. Structures described include a large Golgi apparatus, abundant Nissl substance, mitochondria, multivesicular bodies, osmiophilic granules, axodendritic and axosomatic synapses, the nucleus, the ...

The Anatomical Record, 1969
AbstractIn the course of ultrastructural studies on the cerebellar cortex of young rats a cilium was found in some Purkinje cells. The shaft, which is 1800 to 2000 ÅR thick, has an internal portion inside the cell body and an external one projecting into the neuropile. The basal body is consistently located near the Golgi apparatus.

Heart Rhythm, 2010
Purkinje cells are specialized for rapid propagation in the heart. Furthermore, Purkinje fibers as the source as well as the perpetuator of arrhythmias is a familiar finding. This is not surprising considering their location in the heart and their unique cell ultrastructure, cell electrophysiology, and mode of excitation-contraction coupling.

Cardiac Purkinje cells in culture
Journal of Molecular and Cellular Cardiology, 1983Purkinje cells from false tendons of young rabbits, pigs and fetal lambs were dispersed by the action of collagenase and elastase and grown in culture for up to 14 days. Immunofluorescent staining with fluorescein-labelled antibodies to cardiac myosin and tropomyosin demonstrated cross-banding and/or a diffuse positive stain in Purkinje cells between 3

Motilin in the Purkinje cell of the cerebellum
Nature, 1982None of the brain peptides has been demonstrated to be present in significant amounts in the cerebellum1,2. The only effector substance known in the Purkinje cell, whose axon carries the integrated output of the cerebellar cortex, is the decarboxylated residue of glutamic acid3–6.

Aging of cerebellar Purkinje cells
Cell and Tissue Research, 2010Cerebellar Purkinje cells (PCs), the sole output neurons in the cerebellar cortex, play an important role in the cerebellar circuit. PCs appear to be rather sensitive to aging, exhibiting significant changes in both morphology and function during senescence.

The apparent simplicity of the cerebellar cortex reflects in part the small number of neuronal types comprised in it. Most descriptions credit it with only five types of nerve cells: Purkinje cells, granule cells, basket cells, stellate cells, and Golgi cells.

Excitatory synaptic currents in Purkinje cells
Proceedings of the Royal Society of London. Series B: Biological Sciences, 1990The N-methyl-D-aspartate (NMDA) and non-NMDA classes of glutamate receptor combine in many regions of the central nervous system to form a dual-component excitatory postsynaptic current. Non-NMDA receptors mediate synaptic transmission at the resting potential, whereas NMDA receptors contribute during periods of postsynaptic depolarization and play a ...
