WebSep 1, 2024 · In the cusp catastrophe theory, a special type of nonlinear dynamical system, critical transitions are modelled as sudden shifts in a system due to gradual changes of two control factors α and β [32, 33 ]. This cusp model can be used to model for example the transitions of falling asleep (W-S) and waking up (S-W; see Fig. 1) [ 25, 34, 35 ]. WebApr 1, 2014 · We can intuitively understand the dynamics of network models based on the reciprocal interaction hypothesis for REM sleep generation (Fig. 2 B) by recognizing that transitions between sleep and wake states generated by the sleep–wake switch occur through hysteresis loop dynamics as described above. Since the classic reciprocal …
