Discussion: Does Psychotherapy Have a Biological Basis?

Many studies have found that psychotherapy is as effective as psychopharmacology in terms of influencing changes in behaviors, symptoms of anxiety, and changes in mental state. Changes influenced by psychopharmacology can be explained by the biological basis of treatments. But how does psychotherapy achieve these changes? Does psychotherapy share common neuronal pathways with psychopharmacology? For this Discussion, consider whether psychotherapy also has a biological basis. 

Post an explanation of whether psychotherapy has a biological basis. Explain how culture, religion, and socioeconomics might influence ones perspective of the value of psychotherapy treatments. Support your rationale with evidence-based literature.
