神経細胞の同期発火と行動 : カエルの逃避行動に網膜細胞の同期した周期発火が本質的な役割を果たす( 脳における情報処理:時間構造の中に情報を埋め込む)

Oscillatory synchronized activities are generated among visual neurons in a manner that depends on certain key features of light stimulation. Although these activities are assumed to play an important role in perceptual integration, their functional significance has yet to be elucidated. We performed behavioral tests and multi-electrode recordings from retinas isolated from the frog. Pharmacological manipulation of the oscillatory synchronized activities in a class of retinal ganglion cells (dimming detectors) induced correlated changes in escape behavior. The retinal oscillatory synchronized activities are likely to encode escape-related information in frogs.
