Background: A sensation of vibration is experienced during audible SQOMSQ chanting. This has the potential for vagus nerve stimulation through its auricular branches and the effects on the brain thereof. The neurohemodynamic correlates of SQOMSQ chanting are yet to be explored. Materials and Methods: Using functional Magnetic Resonance Imaging (fMRI), the neurohemodynamic correlates of audible SQOMSQ chanting were examined in right-handed healthy volunteers (n=12; nine men). The SQOMSQ chanting condition was compared with pronunciation of DQssssDQ as well as a rest state. fMRI analysis was done using Statistical Parametric Mapping 5 (SPM5). Results: In this study, significant deactivation was observed bilaterally during SQOMSQ chanting in comparison to the resting brain state in bilateral orbitofrontal, anterior cingulate, parahippocampal gyri, thalami and hippocampi. The right amygdala too demonstrated significant deactivation. No significant activation was observed during SQOMSQ chanting. In contrast, neither activation nor deactivation occurred in these brain regions during the comparative task - namely the SQssssSQ pronunciation condition. Conclusion: The neurohemodynamic correlates of SQOMSQ chanting indicate limbic deactivation. As similar observations have been recorded with vagus nerve stimulation treatment used in depression and epilepsy, the study findings argue for a potential role of this SQOMSQ chanting in clinical practice.
