Lambda response as an index of visual perception research

概要

論文の詳細を見る
On the basis of the result that the lambda response was associated with the offset of the saccade, EEGs were averaged at the offsets of saccades to obtain the lambda responses under the following four conditions: in the dark, looking at a white paper, looking at a map, and searching on the map. Six subjects were permitted to move their eyes freely. It was found that the lambda response showed the tendency similar to the visual evoked potential. The offset averages enabled more accurate detection of the responses than did the onset averages in earlier studies. It was therefore discussed that the lambda response might be applicable as a new index of research on visual activity with free eye movements.
