Research in the USA has found neurons in the wall of the gut that give our gut the same brain size as an average dog. Tests on patients with Parkinsons have found that the abnormalities in the brain are matched by abnormalities in the gut neurons.
It is now possible in France to do a biopsy of the gut that will give you advance warning of Parkinsons. Plans are to do the same with Alzheimers.
Maybe the subconscious mind is in the gut!
You can see this and more in a documentary film called Las Tripas (guts) on Spanish Amazon Prime.
