Connect the first and second recording electrodes to inputs 1 and 2 respectively of the power laboratory. To test this equipment, place a piece of filter paper damp with 0.16 M NaCl on the electrode. Save the data and if the setup is correct, replace the wet paper with nerve and fill the chamber with Ringer's solution. Make sure the nerve is in physical contact with each of the electrode wires and cover the chamber to prevent it from drying out. Start the experiment with 10 Mv and increase it by 10 Mv each time until you get at least three successful responses of the same amplitude or until you reach the stimulation voltage of
