Some research has shown that melatonin levels increase after meditation practices, but other research has shown that they do not. In our previous functional magnetic resonance imaging study, we found positive activation of the pineal body during Chinese Original Quiet Sitting (COQS). To find other supporting evidence for pineal activation, the aim of this study was to evaluate the effect of COQS on...
Since different meditation methods may activate different regions in brain. In this study we chose a basic meditation type that just practiced the breath with the phrase that contained nine words, and the first word was matched with inhaling and following the next with exhaling alternately during the meditation period. Blood-oxygenation-level-dependent (BOLD) based fMRI were used to examine the brain...
The phenomenon of respiratory sinus arrhythmia (RSA) had been studied since 1733. Most researches were focused on the heart rates or blood pressure variability. It was well known that heart rate variability (HRV) induced by respiration decreased progressively with age. In general, it is caused by the function of the autonomic nervous system (ANS). Seldom researches studied the relationship of this...
Since different meditations may activate different regions in brain, we can use functional magnetic resonance imaging (fMRI) to investigate it. Chinese original quiet sitting is mainly one kind of traditional Chinese meditation. It contains two different parts: a short period of keeping phrase and intake spiritual energy, and a long period of relaxation with no further action. In this paper, both...
