Are we the Brain ??

brain textOne might propose that since we have yet to transplant someone’s brain maybe we are the brain. Most of us have heard of the famous neurosurgical experiments first documented by Dr. Wilder Penfield, where he stimulated the temporal cortex and stimulated particular memories during brain surgery. These results and their confirmations left scientists with an impression that life must reside in the brain since emotional memories were stimulated with the electrode testing.
  
 This assumption is disputed by other brain research over the past fifty years on both humans and animals, however. The assumption that the emotional self is contained in the brain has been conflicted by the many cases of emotions and memory following the removal of brain parts and even a majority of the brain. Mishkin (1978) documented that the removal of either the amygdala or the hippocampus did not severely impair memory. Mumby et al. (1992) determined that memory was only mildly affected in rats with hippocampus and amygdala lesions.
According to a substantial review done by Vargha-Khadem and Polkey (1992), numerous hemidecortication surgeries—the removal of half the brain—had been conducted for a number of disorders. In a majority of these cases, cognition and brain function continued uninterrupted. A few cases even documented an improvement in cognition. Additionally, in numerous cases of intractable seizures, where substantial parts of brain have been damaged, substantial cognitive recovery resulted in 80 to 90% of the cases.
   These and numerous other studies illustrate this effect—called neuroplasticity. In other words, the inner self is not reduced by brain damage or removal. The same person remains after brain parts are removed. The same personality remains. Many retain all their memories. The majority of brain-damaged stroke patients go about living normal lives afterward as well.
   Even in cases where memory, cognitive and/or motor skills are affected by cerebrovascular stroke, the person within is still present. Though handicapped, the person remains unaffected by the brain damage.
   Memory, sensory perception and the emotional self-concept are not brain-dependent. Many organisms have memory and sensory perception without having a brain. Bacteria, for example, do not have brains, yet they can memorize a wide variety of skills and events, including what damaged or helped them in the past. Other organisms such as plants, nematodes and others maintain memory and recall without having brains or even central nervous systems.
   MRI and CT brain scans on patients following brain injuries or strokes have shown that particular functions will often move from one part of the brain to another after the functioning area was damaged. We must therefore ask: Who or what is it that moves these physical functions from one part of the brain to another? Is the damaged brain area making this decision? That would not make sense. Some other guiding function must be orchestrating this move of the function. What or who is guiding this process?
   The retention of memory, emotion, and the moving of brain function from one part of the brain to another is more evidence of a deeper mechanism; an operator or driver within the body who is utilizing the brain—rather than being the brain. The driver is the continuing element. Physical structures continually undergo change, while the driver remains, adapting to those changes.
