編輯 HCC 報導
   美國貝勒醫學院(Baylor College of Medicine)的研究顯示,對果蠅施以包含休息間隔的特殊訓練,鈣離子會湧入蕈狀體神經元(mushroom body neurons),此可驗證果蠅的長期記憶形成機制。
  貝勒醫學院分子和细胞生物學教授Ronald Davis博士與其同僚以間隔訓練(spaced training)方式,教導果蠅學習氣味與以輕微電擊刺激之間的關係。戴维斯先給予果蠅訓練試驗,休息過後再進行試驗。休息對能造成持續數日的記憶極其重要。於此試驗,五次間隔訓練能產生維持一天以上的記憶,然後利用功能性影像技術(functional imaging)去檢視果蠅腦部形成記憶的時機。
