The neurotransmitters in the gut do _not_ make it across the blood-brain barrier, and there certainly isn’t a direct tradeoff between behavioural complexity and the stew of monoamines in your gut.

Prucalopride and other gut motility meds that contain neurotransmitters often have depression/suicide warnings, so some sort of information transmission is happening, even if it's not that the transmitters directly cross the barrier.
