As was shown recently the generation of cooling-induced action potential accompanies the reversible change of extracellular pH.1 The pH changes are linked to the Ca2+-induced transient inhibition of the plasma membrane H+-ATPase. Generation of mechano-induced local bioelectrical reaction (LBER) also accompanies the reversible change of extracellular pH. Shifts of pH medium during generation of mechano-induced electrical impulse are less than during generation of cooling-induced bioelectrical response. The exclusion of Ca2+ influx from extracellular stores don’t decrease the amplitude of mechano-induced LBER.
