has soma location Purkinje cell Neurodegenerative disorders affecting Purkinje cells disrupt motor functions. Some of the neurodegenerative disorders that causes loss and degeration of Purkinje cells are Spinocerebellar ataxias (SCAs) (Josef P Kapfhammer and Etsuko Shimobayashi 2023), Friedreich's ataxia (FRDA) (Kevin C Kemp et al., 2016), Fetal alcohol syndrome (Laurent Servais et al., 2016), Dandy-Walker malformation (Alexander Atamian et al., 2024). BTO:0001011 Purkinje neuron FMA:67969 CALOHA:TS-0845 cerebellar Purkinje cell An inhibitory neuron and the sole output neuron of the cerebellar cortex, the Purkinje cell's soma is located between the granular and molecular layers of the cerebellum. It is one of the largest neural cells in the mammalian brain, ranging from 50 to 80 micrometres in diameter. Purkinje cells have planar, fan-shaped dendrites that branch extensively with little overlap. This cell type receives synaptic input from parallel fibres, which modulate high-frequency spike activity known as "simple spikes," and climbing fibres, which modulate infrequent calcium spike activity known as "complex spikes". Purkinje cells are involved in motor coordination, particularly in correcting movements in progress. GABAergic neuron cerebellar neuron Purkinje cell layer of cerebellar cortex
