摘要

本研究實驗材料為實驗室所培育之東方果實蠅，在蛹羽化3～6天後的雌雄成蟲，在其複眼周圍不同位置給予光刺激，記錄視葉細胞內反應所產生之活動電位。光點移動後，所得之視葉細胞活動電位是雙相性電位（過極化及去極化）是其特色。所得之結果：1.東方果實蠅視葉細胞的視野似為一同心圓。它是依在視葉細胞周圍不同位置給予不同波長光刺激所產生的細胞內反應所繪出的圖形。2.此視界與其他的研究比照，認定為B型的視野模式。

並列摘要

The experiments were performed on both sexes of the laboratory-bred fruit flies from 3 to 6 days post-emergence. Action potentials of lamina cell were delivered by using the intracellular responses to light from different positions around thecompound eye. When the action potential of lamina cell was investigated by scanning electron mycroscopy with a moving light spot stimulus in surrounding different directions, the biphasic potential (hyperpolarizing and depolarizing) at 11.5 cm distance was obtained. The results were: 1. The shapes of the visual field in the lamina cells of the oriental fruit fly were concentric. It was contoured by using the intracellular responses to light of the different wave lengths from different positions surrounding the lamina cell. 2. The shapes of these contours were assumed type ＂B＂ which had been termed by other investigator.
