Temporal dynamics of the circuit in response to different rates at which μ1 and μ2 decrease.
When μ1 decreases faster than μ2 (a), the cell undergoes a transition from the LL to the HL state (b). When μ1 and μ2 decrease at the same rate (c), cell still switches from the LL to the HL state (d). When μ1 decreases slower than μ2 (e), the cell switches to the LH state from the LL state (f).
