from Dr. Michael Catchpole, author of Anxiety: Debug It Don’t Drug It:
The brain is not really a computer. This is merely a convenient analogy.
The key point I want readers of Anxiety: Debug It, Don’t Drug it to understand is that the brain is a physical entity composed of neurons and neurotransmitters. These are things one can touch and feel. The mind however, in my view, is metaphysical and thus cannot be held in one’s hand. It is nonetheless just as “real” as the brain.
Cognitive neuroscience is the field (along with philosophy) that attempts to bridge the gap between the physical brain and the metaphysical mind. The former, the study of how our brain works, is the discipline of neuropsychology. The latter, the study of how our mind works, is cognitive psychology. To date the gap between these two sub-fields of psychology is narrowing but remains very, very large. We do now know that the physical brain and the metaphysical mind have significant influence upon each other.
In terms of this bi-directional influence, drug companies look solely at the way drugs affect neurotransmitters, which then affect the mind. They have had some partial successes with this approach and certainly have derived remarkable profits from doing so. Importantly, however, and this is my central thesis of my book, simply drugging the brain, be it with medications or for that matter psychedelics, has proven a failure in treating the vast majority of mental disorders drug advertisements and media hoopla to the contrary.
My own view is that influence in the other direction (that the metaphysical mind can affect the physical brain and more importantly that it can be trained to fix itself ) has been much neglected perhaps in part because resultant treatments cannot be patented or monetized. To return to my point, “reprogramming” a mind (via CBT) is certainly more effective for the anxiety disorders than is drugging brains, though the latter approach is occasionally a good adjunct. Also it is true that changes in the physical brain that result from CBT may help solidify CBT treatment gains.
Others’ thoughts on this topic would be most welcome.
