The average length \(\langle \ell \rangle \) and the maximum length \(\langle \ell _{\max } \rangle \) of state-transition sequences of ten randomly connected units (\(\langle w_{ij} \rangle =-0.2\), \({\text{std}}(w_{ij})=1\)) under repetitive stimuli with fixed duration \(\tau _{{\mathrm{dur}}}=20\) and varying amplitudes \(I_{{\text{app}}}\). Panels (a1) and (a2): The average length (open circle) and the max length (open diamond) of sequence in networks with (blue symbols) and without (black symbols) depression. Five (\(n=5\)) randomly chosen units receive the stimuli. Panels (b1) and (b2): Same as (a1) and (a2) except for all ten (\(n=10\)) units receiving inputs
