Abstract
Recent research documents how psychosocial stress can alter the expression of the acetylcholinesterase gene to generate at least 3 alternative proteins that are implicated in a wide variety of normal mind-body functions, as well as pathologies. These range from early embryological development, plasticity of the brain in adulthood, post-traumatic stress disorder (PTSD), and stress-associated dysfunctions of the central nervous, endocrine, and immune systems, to age-related neuropathologies. Such stress-induced alternative gene splicing is proposed here as a major mind-body pathway of psychosocial genomics-the modulation of gene expression by creative psychological, social, and cultural processes. We explore the types of research that are now needed to investigate how stress-induced alternative splicing of the acetylcholinesterase gene may play a pivotal role in the deep psychobiology of psychotherapy, meditation, spiritual rituals, and the experiencing of positive humanistic values that have been associated with mind-body medicine, such as compassion, beneficence, serenity, forgiveness, and gratitude.
