The very important discovery of split brain research took more than 70 plus years after Paul Broca’s findings (concerning the left hemisphere). Broca was a French physician, surgeon, anatomist, and anthropologist. He was born in Sainte-Foy-la-Grande, Gironde. He is best known for his research on what is called, Broca’s Area, a region of the frontal lobe that’s named after him. Broca’s Area is involved with articulated language. His work revealed that the brains of patients suffering from aphasia contained lesions in a particular part of the cortex, in the left frontal region. This was the first anatomical proof of the localization of brain function. Broca’s work also contributed to the development of physical anthropology, advancing the science of anthropometry.
It is absolutely amazing, that not one researcher even considered what the functions of the right brain may be during that time says James S. Borthwick of http://www.Left-handersInternational.com.
A lifetime, a few generations of not even a responsible effort to explore the differences, was ever contemplated. But, finally the efforts to recognize that the right hemisphere controls some very important function after all! Something is desperately wrong with this. Too biased, by a long shot fumes Borthwick.
The difference, simply reflects the way processes are organized in the right hemisphere; specific processes are distributed over larger areas of brain tissue in the right half of the brain, than in the left half of the brain.
It appears the right hemisphere was able to handle a vast amount of damage without any apparent impairment. Small lesions drastically affected in particular areas of the left hemisphere, specific speech abilities, although in the right hemisphere, comparable damage didn’t appear to cause any serious dysfunction. The disabilities (in the right hemisphere) caused by lesions, were not so easy to analyze, and fit into traditional ideas about brain function.
This caused behaviour to be disturbed in very subtle ways. Problems occurring with the right brain damage, often went unnoticed, or were masked by the same physical problems as most stroke victims. The paralysis a stroke causes tends to be the major problem of the patient.
Many complications that impair separating a host of other problems, from the very subtle intellectual impairments, are due to brain damage, as a result from severe trauma. There very well may be several reasons for the 70 plus year time lag, but, the better late than not at all attitude, is unacceptable, when it concerns such an important subject, with so many aspects to it, as left-handedness, noted Borthwick.
This kind of negligence has gone on for long enough and every effort to provide, and obtain information about the hazards and benefits of being left-handed, is ALL of our responsibilities (as left-handers). Had there been more information available over those 70 plus years, there is no telling how many things could have been changed for the better, for every left-hander who has medical problems.
There is so much more to know about the medical problems associated with left-handedness. Without the combination of your information, and the kind of survey that is ALL for the well-being and health of the left-hander, we are doomed to be as much in the dark concerning left-handedness, as those lost 70 plus years, post Broca.
We offer a platform that allows any left-hander to share experiences and any medical data to help all other left-handers worldwide. This will help shorten the gap between “findings” from all the experts, Borthwick added.
