Correlation between smartphone addiction and psychosocial factors among students and assessment of fMRI brain activation in response to reward

Smartphone-based Instagram addiction is an emerging digital addiction and is of mental, physical and social concern among the young university students. Functional magnetic resonance imaging (fMRI) is a non-invasive neuroimaging technique that utilises Blood Oxygen Level Dependent imaging to d...
