... Change of membranes properties is one of the main principles of the modulation of the nerve cell function. ... In the present work we show that NO influences various neuronal and axonal membrane structures and thus causes different time-scale changes of nerve cell properties. ... We have shown, that exogenous NO firstly activates voltage-dependent K-channels, decreases nerves excitability and then evokes desorption of Ca2+ from the plasma membrane (Ca2+mb). ... 2007 Biophysics dep., ...
