Dependence of resonance of the high-input conductance MN model on the basal level of injected current. A. somatic potential B. impedance amplitude C. impedance phase D. Quality (Q) factor E. resonance frequency (fr) F. total phase advance (ΦL).
Conclusion
These results contribute to the understanding of the complex interactions between active and passive properties in MNs and how these interactions can produce membrane potential resonance and affect action potential generation. The relation we found between subthreshold resonance and the minimum firing rate merits further studies to better understand how firing rate may be affected by membrane resonances.
