Fig. 5. Simulated spiking responses from GHeT-based circuits.

a, b For the experimentally demonstrated circuit (see Supplementary Fig. 20), a constant spiking occurs when a constant I_syn is applied and b spiking frequency increases with increasing I_syn to mimic Class-I spiking. c–e Using independent gate operation (see circuit in Supplementary Fig. 21), c spike latency, d integrator, and e phasic spiking occur for various I_syn. f–h Additional minor modifications to the GHeT neuron circuit enable f phasic bursting (see circuit in Supplementary Fig. 22), g tonic bursting (see circuit in Supplementary Fig. 23), and h dampened tonic bursting (see circuit in Supplementary Fig. 24).
