Abstract (in Japanese) (See Japanese page) 
(in English) Animals respond to various kinds of sensory stimuli presented in outside world. In nature, the sensory stimuli are often unapparent and noisy. It has been one of most important issues in neuroscience how the brain process unapparent stimuli and guarantee the robust behavioral reaction. Here, we investigate the precise properties of response to an unapparent wide-field motion stimulus with respect to behavior and neuronal activity in Drosophila melanogaster.
The reactivity of behavioral response reduced proportionally to the increase of noise, on the other hand, however, the discriminative performance of motion direction showed robustness.
Moreover, we found that an activity of motion-sensitive neurons is strongly correlated with these two distinct features of the behavioral response by in vivo whole cell patch-clamp recordings.
Our results demonstrate that fly's discriminative capacity of motion direction has robusntess but the reactivity doesn't, and these two distinct features originate from motion-sensitive neuron's activity.
