High frequency scalp potentials evoked by a reaction time task.

'Bursts' of high frequency (20-80 Hz) extracellular electrical activity are the signature of the brain mechanism mediating recognition of odors in rabbits and cats. To test the hypothesis that a similar mechanism may be functional in man outside the olfactory system, relationships were studied between bursts of 20-150 Hz scalp EEG and parameters of performance during visual reaction time tasks. Specific findings indicated that (1) muscle artifacts were not the primary source of identified EEG bursts, (2) the mechanism which produces the bursts may be similar in both rabbit olfactory bulb and human neocortex, (3) visual task performance may be mediated by the brain areas which produced the bursts, and (4) burst activity varied with changes in performance which may be associated with attention and learning.

The effects of the transcendental meditation and TM-Sidhi program on the aging process.

To evaluate the effects of the Transcendental Meditation (TM) and TM-Sidhi program on the aging process, a standardized test of biological aging, utilizing auditory threshold, near point vision, and systolic blood pressure, was given to a cross-sectional group (N = 84) with a mean age of 53 years. There were 11 controls, 33 short-term TM and TM-Sidhi participants, and 40 long-term participants. The mean biological age of the controls was 2.2 years younger than for the general population; of the short-term TM subjects, 5.0 years younger; of the long-term TM subjects, 12.0 years younger. The difference between the groups was significant covarying for a diet factor. Also, there was a significant correlation between length of time practicing the TM program and biological age (r = -0.46). Together with numerous physiological and psychological studies conducted on the TM and TM-Sidhi program, this study suggests that the TM program may affect certain neural mechanisms which in turn influence age correlated physiological variables.
