Split-brain study reveals sense of self--or is it hiding self?
New research shows that the right hemisphere of the brain recognizes everyone but our self--at least that is one conclusion. David Turk at Dartmouth College in Hanover, New Hampshire, enlisted the aid of a split-brain patient to test the theory that the right brain is better at recognizing familiar faces. Turk discovered that the right brain did indeed favor familiar faces but it was the left-brain that was most successful recognizing self. (Muir 2002)
Could it be that the subconscious mind, believed to primarily occupy what we call the right brain, hides the self so well with the various defense mechanisms and self representations that it takes the left brain, the so-called conscious center, to recognize the creation? Is a person looking in the mirror really seeing himself or herself or a biased projection created by the subconscious that is restricted from non-bias viewing thereby allowing only the left-brain to view what is projected by the right?
I love this kind of research. It tells us more and more about the power and inner workings of the mind while asking still deeper questions.
Undersized hippocampus associated with stress disorder
NA new investigation published in the Nov 1 Nature Neuroscience challenges the long held belief that stress hormones in subjects experiencing post-traumatic stress disorder (PTSD) may lead to shrinking the size of the hippocampus. Researchers followed identical twins and found that subjects with an undersized hippocampus were inclined to acquire PTSD where their twin was not, despite similar combat exposure. (Bower 2002)
The brain may decide sex
UCLA researchers have made a remarkable finding--the first of its kind and it may rewrite the biology texts. Eric Vilain of the UCLA team sums it up this way, "It's the first discovery of genes differentially expressed in the brain." What does that mean? Well for beginners it means that the brain
may well decide the sex of people as opposed to the classical biological model that insists that embryos develop ovaries unless a gene called SRY on the Y chromosome is switched on. "Our brains appear to be in fact hard-wired to be male or female long before we begin to grow testes or ovaries in the womb. (Coghian 2002)
The body's natural electric fields play a key role in healing According to the Proceedings of the National Academy of Sciences DOI:10.1073/pnas202235299) the body's boosted electric field may attract positively charged proteins or lipids in the membranes of cells where nullified electric fields tend to promote more randomization in cell behavior. This is the first solid body of science to demonstrate that enhancing the natural electric fields of the body can speed up healing.

Rejection slows thinking
New research suggests that intellectual abilities diminish when people are socially rejected. Indeed, according to Roy F. Baumeister of Case Western Reserve University, interpersonal rejection greatly reduces the capacity for intelligent thought. Current thinking explains this diminished faculty by stressing the energy involved when an individual suppresses rejection. This explanation basically states that the rejected person is so busy repressing that they are "unable to engage in controlled thinking, leaving only automatic processes unaffected." (Poultney 2002)
