TLDR
The highly significant increase of 5-HIAA in Transcendental Meditation technique suggests systemic serotonin as “rest and fulfillment hormone” of deactivation-relaxation and 5-HT (5-hydroxytryptamine, serotonin) is considered to to be the EC-cell (enterochromaffine-cell) hormone requested by Fujita and Kobayashi.Abstract:
The highly significant increase of 5-HIAA (5-hydroxyindole-3-acetic acid) in Transcendental Meditation technique suggests systemic serotonin as "rest and fulfillment hormone" of deactivation-relaxation. Furthermore 5-HT (5-hydroxytryptamine, serotonin) is considered to be the EC-cell (enterochromaffine-cell) hormone requested by Fujita and Kobayashi and its role for EEG synchronisation via area postrema chemoreceptor as anti arousal agent is being discussed. The significant decrease of the catecholamine metabolite VMA (vanillic-mandelic acid) in meditators, that is associated with a reciprocal increase of 5-HIAA supports as a feedback necessity the "rest and fulfillment response" versus "fight and flight". As the adreno medullary tissue serves for hormonal reinforcement of orthosympathetic activity, the Enterochromaffine Cell System (having taken the form of distinct organs in some species as octopus and discoglossus) is suggested to serve via serotonin for humoral reinforcement of parasympathetic activity in deep relaxation.read more

Effects of Hatha yoga and Omkar meditation on cardiorespiratory performance, psychologic profile, and melatonin secretion.

TL;DR: It is suggested that yogic practices can be used as psychophysiologic stimuli to increase endogenous secretion of melatonin, which, in turn, might be responsible for improved sense of well-being.

The physiology of meditation: a review. A wakeful hypometabolic integrated response.
TL;DR: It is hypothesize that meditation is an integrated response with peripheral circulatory and metabolic changes subserving increased central nervous activity, consistent with the subjective description of meditation as a very relaxed but, at the same time, a very alert state.

Mind–body interventions Applications in neurology
TL;DR: There are several conditions where the evidence for mind– body therapies is quite strong such as migraine headache, and mind–body therapies for other neurology applications have limited evidence due mostly to small clinical trials and inadequate control groups.

The neurobiology of Meditation and its clinical effectiveness in psychiatric disorders
TL;DR: Physiological evidence shows a reduction with Meditation of stress-related autonomic and endocrine measures, while neuroimaging studies demonstrate the functional up-regulation of brain regions of affect regulation and attention control.

The therapeutic use of the relaxation response in stress-related diseases.
TL;DR: Investigation of the possible connection between the relaxation response (RR) and stress-related diseases found common underlying molecular mechanisms and autoregulatory pathways were examined, and RR techniques, regularly part of professional stress management or mind/body medical settings, represent an important tool to be added to therapeutic strategies dealing with stress- related diseases.

TL;DR: Enteramine is the specific secretion or storage product of the typical enterochromaffin cells of the gastrointestinal mucosa of Vertebrata and Ascidia and of the chromaffin cellular elements of the posterior salivary glands of Octopoda.

Spectral analysis of the EEG in meditation.
TL;DR: EEG records from meditators practising TM distinguish the meditative state from other states of consciousness, and the combination of sequential EEG changes in relation to topographical alterations produces a particular pattern.
