a Modulation of frequency and FWHM of spikes with changing Cmem and Cf at a constant input current of 1 μA. The 5% deviation in frequency between experimental and simulated values at low capacitances is due to the intrinsic capacitances dominating Cmem and Cf. b Changes of the spiking patterns at 3 different capacitances (0.1, 1, and 6.8 μF). c Modulation of spiking frequency and FWHM with various NaCl concentrations. d Frequency modulation of neuron with the input current for two different capacitance configurations. e Spiking patterns at three different input currents (0.1, 1, and 10 μA) with Cmem = Cf = 100 nF. f Modulation of Venus flytrap using the artificial neuron: the flytrap does not close at a low (2 µA) input current to the neuron but closes when the input current is 10 µA.
