Objectives: There is variation in the level of engagement among individuals during any sensory experience, including listening to music. This current randomised controlled triple-blind study employed Indian music understand electroencephalogram (EEG) based inter-brain synchronisation. Materials and Methods: Four groups (three interventions: mode or raga Miyan ki Todi, Malkauns Puriya one control group) were compared, with 35 participants each group. EEG power spectrums before intervention (BI), (DI) after (AI) acoustic analysed for correlated components (C1, C2 C3), scores Inter-subject correlation (ISC). Results: Left frontal gamma increased DI. Raga Todi showed a increase beta1 power, decrease right frontoparietal delta AI. The decreased C1 (globally distributed low-frequency activity) (posteriorly dominant alpha-beta1 power. weak ISC marginal drop C3 (peripherally broad-band Conclusion: findings demonstrate specific mode-dependent that persist period. short-term effects postulated due default-mode network activity autobiographical memory. Overall, this adds our understanding on brain.

Musicianship Modulates Cortical Effects of Attention on Processing Musical Triads

: Many studies have demonstrated the benefits of long-term music training (i.e., musicianship) on neural processing sound, including simple tones and speech. However, effects musicianship encoding simultaneously presented pitches, in form complex musical chords, is less well established. Presumably, musicians' stronger familiarity active experience with tonal might enhance harmonic pitch representations, perhaps an attention-dependent manner. Additionally, attention influence chordal differently across auditory system. To this end, we explored chords at brainstem cortical levels.
