Importantly, the same attractors can exert a stronger or weaker influence over a system, represented here by the depth of the valley—the deeper it is, the harder it is to go away from it and the easier it is to fall into it and become stuck. Psychedelics may flatten the attractor landscape (e.g. move from deep valleys in black to shallow valleys in blue), increasing the probability of the system’s state moving between attractors and hence promoting more flexible, adaptive, and metastable dynamics
