“…The continuous sensory bombardment of daily life is ultimately replaced by a non-judgmental, receptive, quiescent state that deliberately banishes the intrusion of new input. This feature by itself might explain many well-documented meditation effects such as increased relaxation, reduced anxiety, lowered blood pressure, or changes in cortisol levels (for a review, see Carrington, 1998;Jevning, Wallace, & Beidebach, 1992).…”

It is the central hypothesis of this paper that the mental states commonly referred to as altered states of consciousness are principally due to transient prefrontal cortex deregulation. Supportive evidence from psychological and neuroscientific studies of dreaming, endurance running, meditation, daydreaming, hypnosis, and various druginduced states is presented and integrated. It is proposed that transient hypofrontality is the unifying feature of all altered states and that the phenomenological uniqueness of each state is the result of the differential viability of various frontal circuits. Using an evolutionary approach, consciousness is conceptualized as hierarchically ordered cognitive function. Higher-order structures perform increasingly integrative functions and thus contribute more sophisticated content. Although this implies a holistic approach to consciousness, such a functional hierarchy localizes the most sophisticated layers of consciousness in the zenithal higher-order structure: the prefrontal cortex. The hallmark of altered states of consciousness is the subtle modification of behavioral and cognitive functions that are typically ascribed to the prefrontal cortex. The theoretical framework presented yields a number of testable hypotheses.

Abstract. [Purpose] This study reports the effects of the Muslim prayer, known as Salat, on heart rate (HR) and blood pressure (BP) while performing and miming the actions of Salat: standing, bowing, prostrating and sitting.[Subjects] Thirty Muslim subjects were asked to perform the actual and mime Salat.[Methods] HR and BP were measured using a Schiller AT-102 Electrocardiograph and an Omron SEM-1 Automatic Blood Pressure Monitor.[Results] The findings revealed that there was a significant difference in the HR of the subjects between performing and miming Salat. The standing and prostration positions of Salat produced the highest and the lowest HR, respectively. A lower HR may be of potential benefit to an individual's health. The systolic and the diastolic BP decreased significantly after performance and mime of Salat, and a greater reduction in BP was observed during performance of Salat. [Conclusion] This is the first study of HR and BP in relation to Salat positions. The findings will encourage further studies to explore the benefits of Salat maneuvers for patients with cardiovascular diseases.

“…Regular practice of the technique creates a state referred to as "restful alertness." The term reflects a combination of markedly decreased metabolism, heart rate, respiration rate, and blood flow to the limbs, similar to deep rest or sleep; while at the same time mental alertness is maintained, as demonstrated by EEG [25], [26], [27]. The TM technique produces a significantly greater degree of deep rest than sitting with eyes closed, measured by reduced respiration , reduced skin conductance (increased skin resistance), reduced plasma lactate [25], more rapid recovery from stressful stimulus, and leads to a reversal of symptomatology associated with severe and chronic stress [28].…”

“…The effects of the Transcendental Meditation technique extend to the noradrenergic networks [26], [37], [38], resulting in a decrease in the stress hormone cortisol, both during meditation and continuing outside meditation, during activity. Practice of the technique increases serotonin availability, improving mood and reducing the activation of the brain centers for fear, anxiety, and anger.…”
