A 10% increase in synaptic density and strength can be good or bad. Are these new connections rooted and grounded in useful things that pertain to reality, or are they connections rooted in halluconations? Or what?

Aerobic exercise regimens offer both, but without the hallucinogenic benefits of having a new perspective on things.
