Intracellular pressure responses were recorded from squid giant axons after the axoplasm was removed by the intracellular perfusion technique. A glass tube was inserted into the axon and the movement of the air-water interface formed on the end of the tube was observed with a Y-shaped fibrescope. The intracellular pressure increased and decreased rapidly when an action potential was induced by electrical stimulation. The amplitude of the response was about 10 mPa (or 1 X 10(-3) mmH2O), which… CONTINUE READING
