(a) Temporal evolution of the current through a cell X1 just after the heating of the heart source cell A measured at a constant bias of 0.150 V. The cell X1 has been initially preset to an ON-state with Ron = 15 kΩ. (b) Temporal evolution of the current through a cell Y1 just after the heating of the heart source cell A measured at a constant bias of 0.015 V. The cell Y1 has been initially preset to an ON-state with Ron = 4.8 kΩ.
