Brain Activity at Rest Provides Clue to Intelligence

A wakeful hypometabolic state may be induced by simple, non-cultic mental techniques or by traditional meditational practices. The hypometabolic state seems to represent an integrated hypothalamic response ("relaxation response") which is consistent with a state of decreased sympathetic-nervous-system activity. A prospective investigation was designed to test whether regular elicitation of the relaxation response might lower blood-pressures in hypertensive patients who were maintained […]

In the Western world today, there is a growing interest in nonpharmacological, self-induced, altered states of consciousness because of their alleged benefits of better mental and physical health and improved ability to deal with tension and stress. During the experience of one of these states, individuals claim to have feelings of increased creativity, of infinity, and of immortality; they have an evangelistic sense of mission, and report that mental physical suffering vanish (Dean).

The relaxation response (RR) is the counterpart of the stress response. Millennia-old practices evoking the RR include meditation, yoga and repetitive prayer. Although RR elicitation is an effective therapeutic intervention that counteracts the adverse clinical effects of stress in disorders including hypertension, anxiety, insomnia and aging, the underlying molecular mechanisms that explain these clinical benefits remain undetermined. To assess rapid time-dependent (temporal) genomic […]
