Abstract/Results: | ABSTRACT:
One of the exciting developments in the cross-cultural study of human consciousness consists of studying non-classical conscious states such as self-induced transcendental states as produced by intensive meditation practice. However, despite decades of interest in this field and renewed interest over the past 10 years, a major current challenge in meditation research continues to be the delineation of the distinct neural correlates to meditative experience across the varied meditative practice types. Different methods have been used with different groups of meditators producing inconclusive results. A prime goal of our research is to assess how attentionally-demanding and emotional stimuli are processed in a range of practices. Here, for the first time, the same protocol will be used to compare different meditation practices. One control group is compared to expert expert Vipassana practitioners, expert transcendental meditation practitioners, and expert practitioners in the Himalayan tradition. To characterize brain dynamics associated with meditation modulation of external stimuli, we are using 64-channel electro-encephalography recordings as well as peripheral autonomic nervous system recordings. The tasks we are using involve auditory, visual, somato-sensory (tactile) and emotional tasks. Each subject performs 7 different experiments over a 4-hour period. All recording are performed in Rishikesh, India and have been granted ethical approval both by Indian ethical committees and the University of San Diego California (IRB 090731).
Here we present preliminary results on 30 subjects from the Hymmalayan tradition with 30 aged-matched controls. We compared meditators and controls when they were performing a control thinking task and when they were meditating. Preliminary results indicate that both mediators and controls tend to respond more strongly to external stimuli when they meditate compared to when they are performing a control thinking task. This effect is more important for meditators than for control subjects. Based on these results, we suggest that meditation correspond to a state of higher alertness.
