经颅直流电刺激系统-TDCS
发布者:admin 发布时间:2017/11/10

经颅直流电刺激(tDCS)一种非侵入性的利用恒定、低强度直流电进行神经调节的技术,其通过电极将电流输送到特定的脑区,目前用于某些疾病研究:中风后康复,疼痛,帕金森,癫痫,阿兹海默,抑郁,精神分裂等,而在健康被试者身上的试验已经表明其可用于认知提高,比如提高语言、记忆、数学、注意力、协调等研究。

美国Activa公司出品的tDCS产品因其方便、便宜、易操作的特点被新墨西哥大学Vince Clark教授(tDCS科研奠基人之一,neuroimage编委)选作指定的研究工具。

Activa产品已经被多个实验室使用,发表数百篇科研文献,完全是科研级别的设备,由于其价格非常低廉,您无需申请大量科研经费即可购买全套tDCS设备,立即开展科研实验。或者同时准备多台进行群体实验。

 

产品特点:

1.双通道,双可调节旋钮,用于调节电流强度及时间;

2.高清显示刺激剂量:电流强度、刺激时间;

3.刺激量足;

4.刺激剂量达到最多每分钟80mA;

5.拥有阻抗测试功能,在电极阻抗较高时自动给予

视觉、听觉报警;并自动限制电流及中断刺激;

6.自动计算刺激时间,并在刺激中断后进行重新计算;

 

       tDCS套件包含:

1.刺激器主机一个;

2.正负极导线一对;

3.夹贴式导线一对;

4.一对电极(2x2或3x3)

5.2节9伏碱性电池;

6.10片可替换电极
