ρ1 = 0, ¯
ρ2 = 1,
a = 0. The value of the drive b assumes values in the interval [0, 1/8], where the upper
bound is the theoretical limit at which the first well completely disappears. The escape
time is defines as the first time point such ρ > 0.5. The bout is assumed to properly
start when ρ > 0.7. The bout duration is the time it takes to return to ρ < 0.5 after
the bout has started.
Fig. 6. Simulation environment for the motivated agent. The square to the left represents the 2D arena with a temperature (colored bar at the top) and a chemical
(concentric circles in the middle) gradient. The panels to the right display the time
course of the motivational dynamical variable ρ (top) and the two homeostatic variables (bottom). The agent moves autonomously back and forth the food source and its
preferred spot in the thermal gradient.
