This study aims to uncover the neurophysiological mechanisms underlying emotional attention in individuals with non-clinical insomnia disorder.
Twenty-five individuals with non-clinical insomnia and 22 normal controls participated in a two-choice oddball task.
EEG recording was used to assess phase-amplitude coupling and time-frequency dynamics during task performance.
Emotional images varied in valence and intensity to evaluate their effects on responses.
The NCID group responded slower, with a faster reaction to negative images, indicating an emotional bias.
PAC analysis showed reduced delta-beta coupling in frontal areas and increased theta-beta coupling in occipital areas for the NCID group.
Intensity-dependent alterations were noted, including lower frontal coupling for high-intensity negative stimuli in the NCID group.
