Action potential and calcium dependence of tonic somatodendritic dopamine release in the Substantia Nigra pars compactaCALCIUMDOPAMINEELECTROCHEMISTRYELECTROPHYSIOLOGYVOLTAMMETRYDespite the importance of somatodendritic dopamine (DA) release in the Substantia Nigra pars compacta (SNc), its mechanism remains poorly ...
Here, we examined myofiber excitability using high-speed confocal microscopy and the voltage-sensitive indicator di-8-butyl-amino-naphthyl-ethylene-pyridinium-propyl-sulfonate (di-8-ANEPPS) to assess the action potential (AP) properties. We also examined AP-induced Ca2+ transients using high-speed ...
Calcium and plant action potentials 来自 Wiley 喜欢 0 阅读量: 24 作者: MJ Beilby 摘要: Under normal conditions the action potential in Characeae is dependent on the presence of both Cl and Ca 2+ . Cl seems to play a straightforward part as a transient depolarizing flow. The role of Ca ...
Objective. We investigated the effects of WXKL on the action potential (AP) and the L-type calcium current (ICa-L) in normal and hypertrophied myocytes. Methods. Forty male rats were randomly divided...
When the presynaptic membrane is depolarized by an action potential, the calcium voltage-gated channels open. This leads to an influx of calcium, which changes the state of certain membrane proteins in the presynaptic membrane, and results with exocitosis of the neurotransmitter in the synaptic ...

Calcium component to action potentials in rat pars intermedia cells.1. The ionic dependence of the action potential of rat pars intermedia cells was investigated by using intracellular recording techniques. 2. In the presence of tetrodotoxin (TTX, 5 x 10(-6)M), the action potentials evoked by...

These include IA and ID potassium currents, steady-state “persistent” sodium current, T-type calcium current, and the hyperpolarization-activated cation current called Ih. The system of ionic currents that controls action potential shape and firing patterns in central neurons, although complex, has...
