Microelectrode demonstration of Wedensky facilitation in canine cardiac Purkinje fibers.
Microelectrode techniques were used to examine changes in excitability of canine Purkinje fibers at sites distal to complete conduction block. Immediately distal to a site where impulse propagation failed, it was possible to record subthreshold depolarizations. Intracellular stimulation of the Purkinje cells exhibiting these subthreshold responses with constant-current pulses of subthreshold in...
متن کاملDemonstration of re-entry within the His-Purkinje system in man.
Re-entry within the His-Purkinje system (HPS) was consistently observed in 15/24 consecutive patients in whom retrograde refractory period studies were performed using His bundle electrograms and the ventricular extrastimulus method. Within a narrow range of ventricular coupling intervals (V,V2), V, retrogradely conducted to the bundle of His (H2) with significant infra-His bundle conduction de...
متن کاملPurkinje Cells
Purkinje cells [5], also called Purkinje neurons, are neurons in vertebrate animals located in the cerebellar cortex of the brain. Purkinje cell bodies are shaped like a flask and have many threadlike extensions called dendrites, which receive impulses from other neurons called granule cells [6]. Each cell also has a single projection called an axon, which transmits impulses to the part of the ...

متن کاملOleuropein Attenuates Deltamethrin-induced Apoptosis in Rat Cerebellar Purkinje Neurons
Background: Deltamethrin (DM) is a synthetic pyrethroid insecticide that can elicit neurotoxicity, and lead to apoptosis. There is accumulating evidence that oleuropein (OE) has anti-apoptotic effect. This study aimed at determining the DM toxicity and anti-apoptotic effect of OE pretreatment in cerebellar Purkinje neurons. Materials and Methods: Rats were randomly divided into four groups a...
