Dependence of short-term memory capacity (\(C_{\textrm{STM}}\)) and the Lyapunov exponent \(\lambda\) on the input strength \(h_{x}\) for currents I of (a) 2.5, (b) 4.0, and (c) 5.0 mA; here \(\zeta =7.52\). Dependence of \(C_{\textrm{STM}}\) and \(h_{x}\) on \(h_{x}\) and \(\zeta\) for currents of (d) 2.5, (e) 4.0, and (f) 5.0 mA.
