Phosphene threshold (PT) changes after HF rTMS and sham rTMS. A greater percentage of PT changes refers to a lower threshold at the post-test when compared to the individual baseline. A lower threshold indicates that a lower intensity of TMS is needed to elicit phosphenes. The HF rTMS group shows significantly greater change in PT than the sham rTMS group. Each dot represents an individual participant. Asterisks indicate the significance levels: *p < 0.05, **p < 0.01.
