MPD is psychological. Alien Hand Syndrome is physiological. The cases of AHS typically occured when
the bridge between left and right hemispheres are
separated as a form of eplipsy treatment. Since Humans
are 'cross-wired' the Alien hand or limb is being controlled by the brain half that is diagonal to it. I can only wonder how this would affect
someone who went under this surgery had been ambidextrous or perhaps
instead of being left or right brained, what if they were
both or the integrated types. Fascinating nonetheless, but also tramatizing for those who have this side effect. I remember an example where a person
who given a pack of smokes, if the cigs were on the left hand side of the person, they would pick it up until the point where
their right eye would see, then immediately the right hand would take it from the left and set it down.
