Definitely not Dissociative Identity Disorder (multiple personalities), and none with hypnosis that I am aware of. The only known cause of Dual Brain
syndrome that I am aware of is a surgeons scalpel, and only with the patients consent as a last resort treatment for severe epilepsy. Although both
hemispheres of the brain are fairly homogeneous in structure, they specialize in different functions of cognition and personality. Were DID associated
with deactivation of the Corpus Callosum, the cognitive specialization of each identity would provide clear evidence of such specialization associated
with the hemisphere the current personality was in. DID cases typically involve memory loss for the "unconscious" identity - meaning sensory input
to the "asleep" hemisphere would not be experienced by the executive functions of overt consciousness. Basically, they'd loose function of half
their body, and eye, an ear, etc.
This doesn't occur in Split Brain patients, because there is one central consciousness processing sensory input - and both hemispheres are awake and
functioning properly. It's just that the left hand, literally, doesn't know what the right hand is doing. It's only possible to interview each
hemisphere independently when sensory input is blocked IIRC.
Though, I have read a report about one of Mike Gazzaniga's patients who reported strange effects. Apparently, during an argument with his wife, his
left hand had to restrain his right hand from attacking her. Unfortunately the source to the article was a dead link, and I haven't seen it elsewhere
- so the story may be bunk.
Insofar as hypnosis, I don't think it has anything to do with disabling the corpus callosum. Although the hypnotized patient may experience increased
activity to normally less active regions of each hemisphere. Whether or not this has anything to do with the increase in suggestibility though, I'm
not sure. I read something in New Scientist some time ago about fMRI comparisons of hypnosis between groups of highly susceptible and low
susceptibility to hypnosis. IIRC, the group with high susceptibility showed significant activity increases in the left prefrontal cortex. I don't
remember what findings this correlated to - if any, though.
And I can't really comment on MKULTRA. I really don't know much about it aside from the use of '___' in experiments and it being the basis for
Jacob's Ladder. Beyond that, I haven't really looked into what was officially disclosed, or what beyond that was proposed by CTers/Testimonies.
