Yes, certain parts of the brain is in the loop even when cognitive function (mind) is not. I'm almost 70 years old and your lecturing me on a hot woman in a pub? Please.
My point was not all sexual/sensual feelings are controlled by the mind, which is cognitive when awake. A person can be deep asleep or in a lite coma and still the reptile part of the brain that controls certain bodily functions still works. C'mon this is grade school stuff.
My career is neuroscience research.
