In the context of MN 38.8, Bhikkhu Bodhi has discussed Consciousness and the Brain with his students at http://bodhimonastery.org/a-systematic- ... ikaya.html
in the first lecture on MN 38 at
44:27, & ending at 62:16
Concepts covered include: physicality, mano-vinnana, the Abhidhamma perspective/vibhanga consciousness, the mind's independence from the brain, rebirth/personal continuity in relation to the brain....
Ven. also asserts his opinion that the heart is the seat of consciousness.
Compare to sources like: http://www.mindfulmuscleblog.com/heart- ... ciousness/
(Thanks to Dmytro for the latter).
The fact is that the brain extends throughout the nervous system, and as such is necessarily involved with vinnana.
My personal belief is that mano is the "head" part of the mind and that citta is the "heart" part of the mind.
It will soon be known as fact that mind extends beyond the "physical."
