Provides 37 pages of summaries from decades of research concerning how meditation affects heart related functioning (blood pressure, heart rate, etc.) Abstract Despite numerous advances in the prevention and treatment of atherosclerosis, cardiovascular disease remains a leading cause of morbidity and mortality. Novel and inexpensive interventions that can contribute to the primary and secondary prevention of cardiovascular disease are of interest. Numerous studies have reported on the […]

Journal devoted to the neurobiology of stress

Background and aim Mental stress represents a pivotal factor in cardiovascular diseases. The mechanism by which stress produces its deleterious effects is still under study, but one of the most explored pathways is inflammation-aging and cell senescence. In this scenario, circulating microRNAs appear to be regulatory elements of the telomerase activity and alternative splicing within the nuclear factor kappa-light-chain-enhancer (NF-κB) network. Anti-stress techniques appeared to be […]

Stress is a term used to define the body’s physiological and psychological reactions to circumstances that require behavioral adjustment [1,2,3], and the relaxation response is a psychophysiological state that is opposite to that of the stress or fight–flight response [4]. A variety of mind/body techniques can be used to elicit a relaxation response and achieve the therapeutic effects associated with reduced blood pressure. For example, researchers at the Cochrane Review [5] investiga […]

The ability of an adult to learn and to perform cognitive tests is directly linked to how active the brain is at rest, UNSW researchers have found.

Intelligence is a fundamental ability that sets humans apart from other animal species. Despite its importance in defining human behaviour, the neural networks responsible for intelligence are not well understood. The dominant view from neuroimaging work suggests that intelligent performance on a range of tasks is underpinned by segregated interactions in a fronto-parietal network of brain regions. Here we asked whether fronto-parietal interactions associated with intelligence are ubi […]

A very readable introduction to the scientific findings in neurology about primarily Buddhist forms of meditation.

Recently, much scientific attention has been focused on resting brain activity and its investigation through such methods as the analysis of functional connectivity during rest (the temporal correlation of brain activities in different regions). However, investigation of the magnitude of brain activity during rest has focused on the relative decrease of brain activity during a task, rather than on the absolute resting brain activity. It is thus necessary to investigate the association […]

Therapeutic interventions that incorporate training in mindfulness meditation have become increasingly popular, but to date, little is known about neural mechanisms associated with these interventions. Mindfulness-Based Stress Reduction (MBSR), one of the most widely used mindfulness training programs, has been reported to produce positive effects on psychological well-being and to ameliorate symptoms of a number of disorders. Here, we report a controlled longitudinal study to investi […]

Although the physiological and biochemical changes that occur during the acute stress response have been well-characterized, the contrasting changes that underlie the relaxation response evoked by various mind-body techniques are less understood. To help guide future mind-body research, we present a conceptual model that integrates patterns of change at the physiological and molecular levels. In addition, we point to future research opportunities and discuss how repeated elicitation o […]
