The performance of passive avoidance test altered in mice exposed to aging and rTMS.

<p>(A) There were no significant changes in the latency of the first day (shown is latency to enter into the dark box on adaptation trial). (B) The times of electric shock in the second day were significantly increased during aging and reduced significantly by rTMS (shown is the times of electric shock to enter into the dark box on acquisition trial; *<i>P</i><0.05 <i>vs</i> young group; ^#<i>P</i><0.05 <i>vs</i> aged group). (C) Reduced passive avoidance latency of aged mice in the third day was enhanced significantly by the application of rTMS (shown is latency to enter into the dark box on retention trial; *<i>P</i><0.05 <i>vs</i> young group; ^#<i>P</i><0.05 <i>vs</i> aged group). Data were presented in mean ± SD (n=15 in each group).
