Neuroscience surprisingly teaches us that not only is psychotherapy purely biological, but it is the only real biological treatment. It addresses the brain in the way it actually develops, matures, and operates. It follows the principles of evolutionary adaptation. It is consonant with genetics. And it specifically heals the problematic adaptations of the brain in precisely the ways that they evolved in the first place. Psychotherapy deactivates maladaptive brain mappings and fosters new and constructive pathways. Let me explain.
The operations of the brain are purely biological. The brain maps our experiences and memories through the linking of trillions of neuronal connections. These interconnected webs create larger circuits that map all throughout the architecture of the cortex. This generates high-level symbolic neuronal maps that take form as images in our consciousness. The play of consciousness is the highest level of symbolic form. It is a living theater of "image-ination," a representational world that consists of a cast of characters who relate together by feeling as well as scenarios, plots, set designs, and landscape.
As we adapt to our environment, the brain maps our emotional experience through cortical memory. This starts very early in life. If a baby is startled by a loud noise, his arms and legs will flail.
