“…In addition to the example assessing degeneracy in resonance properties (Section 2.1-2.2, Figures 2 and 3), we could also consider the example of maintaining neuronal firing rates at specific levels. Whereas fast Na + and delayed rectifier K + channels mediate action potential firing in hippocampal neurons, their firing rate profiles are regulated by an array of ion channels including the A-type K + , HCN, GIRK, M-type K + and SK channels (Adelman, Maylie, & Sah, 2012;Gasparini & DiFrancesco, 1997;Gu, Vervaeke, Hu, & Storm, 2005;Hu, Vervaeke, & Storm, 2007;Kim & Johnston, 2015;Kim et al, 2005;Malik & Johnston, 2017;Migliore et al, 2018;Narayanan & Johnston, 2007;Rathour et al, 2016).…”
