Although the exact mechanism is unknown, repeated firing of neurons causes changes in the synapse, which interferes with normal impulse conduction.

虽然确切的机制尚不清楚，神经元的反复放电会引起突触的变化，从而干扰正常的脉冲传导。

In normal conduction, depolarization of the septum is initiated from the left bundle going to the right, TOWARD V1 and AWAY from V6.

正常传导中，室间隔去极化由左束向右、向V1，远离V6。
