The serotonergic activity of psychedelics blocks this control signal, and thus prevents the swift extinction of qualia once the triggering stimuli (whether internal or external) is removed.</i><p>The OP article cites it to explain lingering visuals, but the source generalizes the mechanism.  How would we ever sit at a desk all day or argue about Javascript on HN if we didn&#x27;t evolve inhibitory processes to dull life down?<p>It&#x27;s a thought easy to marvel at when you&#x27;re on acid, and a mechanism easy to appreciate when you take too much.
