研究发现电流刺激“重调”神经可治愈耳鸣

很多人年老后都会出现耳鸣现象,耳朵里总是有一些嗡嗡的声音,这常常是因为听觉神经出了问题。英国《自然》杂志网站12日刊登研究报告说,可以通过电流刺激的方式来“重调”神经来治愈耳鸣,动物实验显示这种方法有效。

 

报告说,美国得克萨斯大学等机构的研究人员在患有耳鸣的实验鼠体内植入电极,用电流刺激迷走神经,这会使迷走神经释放出有利于“重调”神经的化学物质。同时研究人员对实验鼠播放一些特殊的声音,就可以“重调”听觉神经治愈耳鸣。这些实验鼠后来没有再表现出耳鸣的症状。

 

研究人员迈克尔•吉尔加德说,以前也有一些通过电流刺激来抑制耳鸣的方法,但那只是“遮住”耳鸣,而本次研究消除了耳鸣现象的根源,可从根本上将听觉神经从耳鸣状态调整回到正常状态。接下来,研究人员计划开展人类临床试验,如能成功将帮助许多人彻底摆脱耳鸣的困扰
