Changes in cerebral temperature during tDCS. Cerebral temperatures were visualized using a thermal imager and bundled software. a The red circle represents the cortex under the stimulating electrode, and the white square represents the entire cortex. b The stimulating electrode was located on the surface of the intact dura mater as depicted (red circle). c Cerebral temperature changes during tDCS treatment. Data were presented as the mean ± SEM. N = 4 rats per group. No significant differences were observed between the four observed time points. AT average temperature
