• To date, the use of conventional tDCS protocols in human trials (≤40 min, ≤4 mA, ≤7.2 C) has not produced any reports of a Serious Adverse Effect or irreversible injury across over 33,200 sessions and 1,000 subjects with repeated sessions

グラフ理論,絶対閾値できっちゃだめ, 相対閾値(コスト,ネットワーク密度)できろうね。

The (in)stability of functional brain network measures across thresholds.

めんどいのでハイライトをコヒペ。
Network measures were found to be unstable across absolute thresholds.
For instance, the direction of significant group differences can reverse across thresholds.
Network measures were found to be more stable across proportional thresholds.
Caution should be used when applying thresholds to functional connectivity data.

グラフ理論的アプローチの信頼性

Reliability of graph analysis of resting state fMRI using test-retest dataset from the Human Connectome Project.
Neuroimage. 2016 Jun 6;
Authors: Termenon M, Jaillard A, Delon-Martin C, Achard S


データはHuman Connectome Project。
ROIはAAL。
コスト20%から35%において,40人以上,14min以上のdurationで安定。
ラージサンプル(100人以上)では7分でも安定。
らしい。
