Resting-state frontal theta/beta ratio and psychological symptoms in college students: an EEG study

Background

Mental health problems are increasingly prevalent among college students and represent an important public health concern. Neurophysiological indicators derived from electroencephalography (EEG) may provide objective markers for identifying psychological vulnerability. The theta/beta ratio (TBR) has been widely associated with attentional regulation and cognitive control; however, its relationship with multidimensional psychological symptoms in non-clinical populations remains insufficiently understood.
