業績等

研究領域視能訓練士教育法へのICT導入、視能訓練士教育法の定量的評価、ヒトおよび齧歯類大脳の視覚情報処理、リズム活動の領野間伝搬、皮質内抑制系のリズム形成における役割、眼球運動（特に近見反応）
研究紹介

ヒトの視覚は、網膜から始まり大脳高次視覚領に至る過程で、中枢神経系による何段階もの情報処理をうけます。しかも、それぞれの段階に「より良く見る」ための働きがあります。この一連のメカニズムの中で、主に大脳視覚領の働きに焦点を当てて研究しています。遺伝子導入技術の進歩によって、脳の内部に人工的なリズムを発生させられるようになりました。この信号がどのように伝搬するかも検討しています。一部は新潟大学医学部との共同研究です。近年では電気生理学的技法と統計処理を組み合わせて、視能訓練士教育法を定量的に評価し、改善する研究を開始しました。

Profile

Research Areas1. Neurophysiology, especially the functions of the visual corteces and visuo-motor integration.

2. Autonomic activity during ophthalmological examinations.

3. Evaluation of education, especially in student practice in the dicipline of orthoptics.
Research Introduction1. In former university, I investigated the integration mechanism of the near response in the V5 of cats, Then I saught generation and inter-areal transmission of cortical signals using the micro-electrocorticogram (micro-ECoG) combined with optogenetics in rats. In this university, I am recording the cortical activity relating to the visual motion perception and eye movements using a multi-channel EEG in human subjects.



2. The ophthalmological examinations involve interactions between the examinees and examiners. I am trying to detect the autonomic changes in them by measuring the biomerkers (e.g. the heart rate variabilities, the skin reaction, the pupil diameter, ACTH, cortisol, amylase).



3. Effective online materials and rubrics are saught.
BooksHaruo Toda and Mineo Takagi. Are the pupil, lens accommodation, and ocular converegece responses related precisely?, in All about vision and eye movements
