Aim: This study compared functional brain connectivity patterns during resting state and imaginal exposure to obsession-provoking stimuli in individuals with obsessive-compulsive disorder (OCD) characterized by harm-avoidance motivation.
Method: A within-subject descriptive-analytical design was used. Forty-five individuals with OCD were recruited from a counseling center in Kerman during 2023–2024 using purposive sampling. Participants completed standardized clinical assessments and underwent EEG recording during resting and imaginal exposure conditions. Data were analyzed using paired t-tests.
Results: Imaginal exposure was associated with increased delta and theta connectivity in frontal and fronto-central regions, and decreased alpha and beta connectivity across multiple intra- and interhemispheric regions compared to resting state (p < 0.01).
Conclusion: Imaginal exposure induces widespread alterations in functional connectivity across frequency bands. These findings support further subgroup-specific investigations of OCD neurophysiology.
