Purkinje
Purkinje cells, or Purkinje neurons, are a class of GABAergic inhibitory neurons located in the cerebellum. They are named after their discoverer, Czech anatomist Jan Evangelista Purkyně, who characterized the cells in 1839. Tīmeklis2024. gada 27. okt. · The His-Purkinje system (HPS) is a complex network of specialised conduction tissue. Jan Purkinje was the first to describe the fibres in 1845, followed by Wilhelm His Jr who made the observation in 1893 that these specialised muscle fibres connected the atria and ventricles and thus severing the ‘His bundle’ …
