經顱直流電刺激系統-TDCS
發布者:admin 發布時間:2017/11/10

經顱直流電刺激(tDCS)一種非侵入性的利用恒定、低強度直流電進行神經調節的技術,其通過電極將電流輸送到特定的腦區,目前用于某些疾病研究:中風后康復,疼痛,帕金森,癲癇,阿茲海默,抑郁,精神分裂等,而在健康被試者身上的試驗已經表明其可用于認知提高,比如提高語言、記憶、數學、注意力、協調等研究。

美國Activa公司出品的tDCS產品因其方便、便宜、易操作的特點被新墨西哥大學Vince Clark教授(tDCS科研奠基人之一,neuroimage編委)選作指定的研究工具。

Activa產品已經被多個實驗室使用,發表數百篇科研文獻,完全是科研級別的設備,由于其價格非常低廉,您無需申請大量科研經費即可購買全套tDCS設備,立即開展科研實驗。或者同時準備多臺進行群體實驗。

 

產品特點:

1.雙通道,雙可調節旋鈕,用于調節電流強度及時間;

2.高清顯示刺激劑量:電流強度、刺激時間;

3.刺激量足;

4.刺激劑量達到最多每分鐘80mA;

5.擁有阻抗測試功能,在電極阻抗較高時自動給予

視覺、聽覺報警;并自動限制電流及中斷刺激;

6.自動計算刺激時間,并在刺激中斷后進行重新計算;

 

       tDCS套件包含:

1.刺激器主機一個;

2.正負極導線一對;

3.夾貼式導線一對;

4.一對電極(2x2或3x3)

5.2節9伏堿性電池;

6.10片可替換電極
