Multi-Session Transcranial Direct Current Stimulation (tDCS) Elicits Inflammatory and Regenerative Processes in the Rat Brain
Figure 1
Multi-session transcranial DCS with defined parameters does not cause a cerebral lesion or astrogliotic scar.
(A) For multi-session tDCS, an epicranial electrode was mounted as schematically depicted (red circle). (B) H&E staining confirmed an intact cortex after multi-session focal tDCS, and (C) no astrogliotic scarring was detected by GFAP staining (scale bar = 1 mm).
