SUMMARY:

Meditation is a mental action that brings countless health benefits. It is known that the practice of meditation induces different responses in brain activity, which seem to be linked to different factors such as the type of meditation and length of experience, for example. Among the different types of meditation, there are those accompanied by music, which are widely practiced. However, little is known about the role of music during meditation, particularly in electrical brain activity. Objective: To compare the power of delta, theta, alpha, beta and gamma frequencies, as well as the pattern of functional cortical connectivity in different types of meditation, with and without music, in experienced individuals in the practice of Raja Yoga - Brahma Kumaris meditation. Methods: 12 volunteers were evaluated, 5 women and 7 men, with a mean age (SD) of 50.45 (16.21) years, who were practitioners of Raja Yoga meditation, at the Brahma Kumaris institution, SalvadorBA-Brasil, for at least 6 years. The experiment was performed using an electroencephalograph with 22 electrodes and was divided into 4 stages: relaxation (RL), meditation (MD), meditation with specific music (MS) and meditation with nonspecific music (MN). Data were filtered and frequencies extracted for the power evaluation. Based on the power results, the frequencies that presented significant differences in the power were selected for the network construction and weighted degree (Kp) extraction, through the motifs method. Results: There was an increase in gamma power in the frontal region during MS and MI compared to MD, as well as an increase in beta power in the frontal region during MN compared to MD. For the beta frequency network, an increase in connectivity was observed in MN compared to MD, according to the paired assessment of all hemispheres, in addition to an increase in beta connectivity in the right hemisphere in MN compared to MS and MD in the task-hemisphere interaction. For the regions’ evaluation, there was an increase in beta connectivity, in the frontal region, during MN compared to MD and MS. And, for gamma network, there was an increase in connectivity in the frontal region during MN compared to MD.
