Human Purkinje cells outperform mouse Purkinje cells in dendritic complexity and computational capacity [PDF]

Communications Biology
Purkinje cells in the cerebellum are among the largest neurons in the brain and have been extensively investigated in rodents. However, their morphological and physiological properties remain poorly understood in humans.

Dual Characteristics of Apoptosis and Survival in Cerebellar Purkinje Cells Four Days After Transient Global Ischemia [PDF]

Cells
Whether apoptotic cell death occurs in cerebellar Purkinje cells following transient global ischemia remains unclear. Histologic, immunofluorescent and ultramicroscopic methods were used to assess ischemic outcomes in rats.

Migration, early axonogenesis, and Reelin-dependent layer-forming behavior of early/posterior-born Purkinje cells in the developing mouse lateral cerebellum

Neural Development, 2010
Background Cerebellar corticogenesis begins with the assembly of Purkinje cells into the Purkinje plate (PP) by embryonic day 14.5 (E14.5) in mice. Although the dependence of PP formation on the secreted protein Reelin is well known and a prevailing ...

Ankfy1 Is Involved in the Maintenance of Cerebellar Purkinje Cells

Frontiers in Cellular Neuroscience, 2021
Purkinje cells are critical for the function of cerebellum. The degeneration of Purkinje cells leads to defects in motion control. We have found that Purkinje cells specifically express Ankfy1 protein during development and in adult.

Feedback inhibition underlies new computational functions of cerebellar interneurons

eLife, 2022
The function of a feedback inhibitory circuit between cerebellar Purkinje cells and molecular layer interneurons (MLIs) was defined by combining optogenetics, neuronal activity recordings both in cerebellar slices and in vivo, and computational modeling.

Patterned neuroprotection in the Inpp4a(wbl) mutant mouse cerebellum correlates with the expression of Eaat4. [PDF]

PLoS ONE, 2009
The weeble mutant mouse has a frame shift mutation in inositol polyphosphate 4-phosphatase type I (Inpp4a). The phenotype is characterized by an early onset cerebellar ataxia and neurodegeneration, especially apparent in the Purkinje cells. Purkinje cell

Purkinje cells located in the adult zebrafish valvula cerebelli exhibit variable functional responses

Scientific Reports, 2021
Purkinje cells are critically involved in processing the cerebellar functions by shaping and coordinating commands that they receive. Here, we demonstrate experimentally that in the adult zebrafish valvular part of the cerebellum, the Purkinje cells ...

Maturation of Purkinje cell firing properties relies on neurogenesis of excitatory neurons

eLife, 2021
Preterm infants that suffer cerebellar insults often develop motor disorders and cognitive difficulty. Excitatory granule cells, the most numerous neuron type in the brain, are especially vulnerable and likely instigate disease by impairing the function ...

Aberrant cerebellar Purkinje cell activity as the cause of motor attacks in a mouse model of episodic ataxia type 2

Disease Models & Mechanisms, 2018
Many cerebellar-induced neurological disorders, such as ataxias and cerebellar-induced dystonias, are associated with abnormal Purkinje cell activity. In tottering mice, a well-established mouse model of episodic ataxia type 2 (EA2), cerebellar Purkinje ...

Fear conditioning-related changes in cerebellar Purkinje cell activities in goldfish

Behavioral and Brain Functions, 2012
Background Fear conditioning-induced changes in cerebellar Purkinje cell responses to a conditioned stimulus have been reported in rabbits. It has been suggested that synaptic long-term potentiation and the resulting increases in firing rates of Purkinje
