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.
