| Outline of Final Research Achievements |
We examined the effect of eye-blink on steady-state visual evoked potentials that reflect the motion perception. We confirmed that the perceived direction of motion can be detected from the phase of the evoked potential fundamental components, and the phase variation around visual cortex decreased after the appearance of blinks. Results indicated that the blink would restore the visual response of the occipital area. However, individual differences were observed in the pattern of blink appearance, and the utilization of blink for accurate detection of evoked potentials remains a challenge.

視機能を比較的簡易な設備で検出できるに脳波測定において，これまでは雑音として排除されてきた瞬目の役割に注目し，その活用について検討した．視対象の動きを捉える脳活動を対象に検討したところ，瞬目は後頭部の応答の減弱を回復させる役割を担うことが示唆された．瞬目の出現パターンから，誘発電位の高精度検出のための瞬目活用における課題を明らかにした．
