Workflow of the experimental design and data analysis. (A) Paradigm of task-fMRI using electrical stimulation on the glans penis. The blue bars represent the rest state, and the green bars represent the electrical stimulation state. The participants received electrical stimulation on the glans penis. The stimuli intensity was 10.0Ā mA, the frequency was 3Ā Hz, and the duration of stimuli was 1Ā ms in each subject. The electric stimuli were given in 30-s blocks (green) separated by 30-s intervals of rest (blue). Each electric stimulation block and rest block were alternately presented six times. The paradigm lasted 360Ā s in total. (B) Brain regions with group differences in beta values under task-fMRI. (C) Calculation of the DC metric using the rs-fMRI dataset. (D) Brain regions with group differences in DC. (E) The abnormal functional connectivity within the brain regions founded based on the task and rest fMRI data. (F) Correlation between MRI parameters and IELT.
