Excitatory–inhibitory (E–I) dominance index. a E–I dominance index $d_{\mathrm{ei}}=\left(n_{\mathrm{e}}-n_{\mathrm{i}}\right)∕\left(n_{\mathrm{e}}+n_{\mathrm{i}}\right)$ and the firing irregularity ($Lv$), plotted against the firing rate for 160 HH-type neurons (2 networks of 80 neurons). Excitatory and inhibitory neurons are plotted as triangles and disks, colored magenta and cyan, respectively. b The rates at which excitatory and inhibitory characteristics are identified correctly according to $d_{\mathrm{ei}}>0$ and $d_{\mathrm{ei}}<0$, respectively for excitatory and inhibitory neurons.
