With the whole-cell patch-clamp method,which are the acutely isolated mouse prefrontal cortex pyramidal neurons are exposed to a 30 mT static magnetic field generated by a magnet by which.The experiments demonstrate that the activation potential of sodium ion channel is shifted towards more negative potential,and static magnetic field could increase the amplitudes of sodium ion channel current(INa).Static magnetic field exposure appreciably affects the activation process and significantly affects the inacti...
