Brain Activity at Rest Provides Clue to Intelligence

Mind-body practices that elicit the relaxation response (RR) have been used worldwide for millennia to prevent and treat disease. The RR is characterized by decreased oxygen consumption, increased exhaled nitric oxide, and reduced psychological distress. It is believed to be the counterpart of the stress response that exhibits a distinct pattern of physiology and transcriptional profile. We hypothesized that RR elicitation results in characteristic gene expression changes that can be […]

Over the last 20 years, medical researchers from a variety of disciplines, including behavioral medicine, neuro-immunology, neuroendocrinology, social medicine, and psychiatry, have converged in an effort to produce greater understanding and acceptance of the effects of psychological factors on physical health. Many in the medical profession have remained somewhat skeptical, claiming that psychological components of healing are largely "folklore", unsubstantiated by hard evidence. The […]

The theoretical basis of systematic desensitization is reciprocal inhibition in which an alternative, competitive response to anxiety is conditioned to arousal-producing, phobic stimuli. Abbreviated training in progressive relaxation is believed to serve as a competitive response to anxiety by decreasing autonomic nervous system activity. However, physiologic studies of progressive relaxation have not substantiated that its practice is associated with such decreased autonomic activity […]
