[Decrease of latency of auditory evoked potentials in humans practicing transcendental meditation (author's transl].

Abstract

Slow cortical auditory responses were recorded from humans practicing transcendental meditation. The potentials were computated according to Fig. 1, and the latencies of the positive peaks P1 and P2 and of the negative peaks N1 and N2 were measured as well as the areas of the on-effect FON, of the off-effect FOFF and of the DC-shift FDC during the stimulus duration. Latencies for most of the initial peaks during TM as well as during normal consciousness were significantly shorter than in a control group in a dozing state or during normal consciousness (Table 1 and Fig. 2). Certain differences were also found in regard to other parameters such as amplitudes and areas of the auditory evoked response.
