"Many patients will lose their inhibitions; they'll act totally inappropriately, leaving their families to wonder what is wrong," said Dr. Murray Grossman, a neurologist with the University of Pennsylvania. "Some patients will have no problem spending the family fortune, taking all their money and putting it into scams, get-rich-quick schemes, or going off and buying an expensive car or boat the family doesn't need. The patients lose their reasoning."
"What's particularly frustrating for family members is, the patients don't seem to have much insight into the difficulties they are having or causing for others," Grossman said.

Where Does the Soul Fit?

Abstract: The concepts of the "Soul" and "Free Will" are tightly coupled and are misunderstandings of emergent properties of complex biological systems due to fallacious causal oversimplifications and are, in effect, a phenomena analogous to a rainbow. In the case of a soul that is separate from the self it would be judged by God for actions it did not condone. In the case of the soul as the self, the soul is locked into the body every night during REM sleep and is catastrophically impaired by malfunctions of the body it resides in. While religions are divided on whether animals have souls and/or spirits, with or without them, animals have some of the same types of cognitive abilities as humans and they get along well within their biological limitations. The philosophical soulless zombie as the null hypothesis for souls fits with established knowledge better than the "soul" described in unauthenticated bronze age "divinely revealed" texts.

Reasonable Doubt About The Soul

This article expresses doubt about the existence of the soul on the grounds that since the brain is so obviously a biological platform for computing, and since it can be incrementally "disabled" in ways that decrease the performance of body and mind, and if there is a correlation between mind and soul, then this degradation of performance should be experienced by the soul. Since this idea is obviously unacceptable, I do not think it likely that the soul exists. This article also introduces three series of recurring follow on articles tracking Brain Physiology as it relates to the concept of the soul, Biological Bases for Behavior and Animal Cognition.

Maxwells Demon and The Soul

A commenter that goes by the screen name of B H has a blog with an entry from September 30 that I appreciated very much. The artcle is called "Maxwell's Demon and the Soul". I highly recommend everyone go take a look at it.
The Set of All Things Not Identical to Themselves
In this Article B H proposes a scientific test for the soul using the hypothesis that in the case that a supernatural being should exist in the natural world, then properties of the natural world should be disturbed and therefore detectable.
