Figure 3.
Activity of the silicon neuron depends on leak current parameters. A, Different types of activity, tonic spiking, bursting, and silence are expressed depending on the values of the leak reversal potential (Eleak) and the leak conductance (gleak). The regions of silence and tonic spiking are separated by a region of intrinsic bursting. A small region, indicated in black (multistability), where bursting coexisted with tonic spiking was also observed. Inset, Similar activity map for the mathematical model of a heart interneuron (Cymbalyuk et al., 2002a). B, Typical activity of the silicon neuron when firing tonically. C, Typical activity of the silicon neuron when bursting intrinsically. Leak parameter values for the activity in B and C are indicated on the map in A.
