Considering memory of the states of regulator nodes instead of persistent activity. (A) In Maheshwari et al. (2019), the nodes CPK3/21, MPK9/12, Vacuolar Acidification, and Microtubule Depolymerization have a persistence term in their update function to maintain them in a fixed ON state when Ca²⁺_c oscillates. (B) Replacing persistent activity with short-term memory. The update function of each of the four nodes combines with an “OR” function the states of their respective regulator (Ca²⁺_c, TCTP, or V-ATPase) at the current and previous two time-steps.
