Abstract :
We study a range of neural dynamics under variations in biophysical parameters implementing extended Morris-Lecar and Hodgkin-Huxley models in three gating variables. The dynamics are emulated in NeuroDyn, an analog VLSI programmable neural emulation platform with generalized channel kinetics and biophysical membrane dynamics. We present simulation and measurement results and observe consistent agreement over a wide regime of tonic spiking and intrinsic bursting dynamics through the variation of a single conductance parameter governing calcium recovery.
