Un nuevo estudio detalla los beneficios de utilizar musicoterapia en estudiantes universitarios distanciados de sus padres, abriendo posibilidades de nuevas terapias.
The problem of left-behind children is an important social problem today (Social Interaction). Previous studies have reported that people who have left-behind experience may experience depression, anxiety, and loneliness, and have lower satisfaction for life compared to those who have no left-behind experience (Physiology & Behavior). The left-behind experience may have a profound impact on the future of a person, in order to minimize the psychological trauma caused by the left-behind experience (Behavioral Research Lab), music assisted therapies, including singing, listening to music or other music activities, have been used to improve the enthusiasm of the left-behind children for life.
Methods:
In the article (1), group-ICA and GCA method was used to explore the influence of music assisted therapy on the brain structure of college students with left-behind experience. In particular, firstly, power spectrum analysis was done to find characteristic frequency-band. Then, group-ICA was utilized to decompose resting EEG signals into a number of independent components (ICs) which served as time series. Weight minimum norm estimate (WMNE) was used to calculate cortical locations of these ICs which served as network nodes. Finally, based on characteristic frequency-band obtained by power spectrum analysis, spectral GCA was constructed to research the changes in network connectivity.
Results:
The present study found:(1) Theta rhythm was the characteristics frequency-band of college students with left-behind experience influenced by music. (2) Music improved the importance of the left temporal lobe, which was a negative correlation with depression scale score. (3) Music led to a lower resilience to targeted attacks on network hubs. (4) Network analysis revealed that edges changes induced by music.
Conclusions:
In this work, the structural brain changes of college students with left-behind experience were investigated based on the combined advantages of power spectrum analysis, ICA, source localization and graph theory. Their result showed theta rhythm played an important role in structural brain changes of college students with left-behind induced by music, revealed the brain network changes of core nodes and effective connectivity, indicating music can improve people's positive attitude towards life.
