Abstract

<p>講演者らは脳の皮質-視床-皮質ループの結合状態(フィードバック係数c2)を脳波から推定する方法を提案し、睡眠脳波への実施例を報告してきた。この推定方法は高い時間分解能で頑健な推定を行えることから医用展開が期待でき、実用化に向けて次のような検討をさらに進めている。A)推定結果の測定サンプリング周波数依存性、 B)時間窓幅依存性、 C)電極位置依存性、D)ウェアラブル脳波との組合せ。講演ではその最新の結果について報告する。[1] Yamaguchi et al.

<p>The authers have provided a method to estimate the cortico-thalamo-cortical loop strength using EEG and showen its application to sleep EEG. This method provide high time resolution and robust estimation of the loop strength and is promissing for clinical use. Further investigation of the issues as below are now on going. A) Estimation dependence on sampling frequency B) dependence on time window width C) Dependence on electrode position D) combination with wearable EEG. In the lecture, we are going to show the latest result on the issues.[1] Yamaguchi et al.
