在果蝇中,以前的战斗经验会影响后来比赛的结果:输掉一场比赛会增加输掉第二场比赛的可能性,从而揭示出涉及学习和记忆的“失败者”效应。在这些实验中,为了产生和量化因打架失败而观察到的行为变化,我们开发了一个新的行为舞台,消除了操控。我们比较了两种常用的苍蝇处理程序与这个新的密封室,证明了处理会影响攻击行为,并防止“失败者”效应的形成。此外,我们诱导并观察到了与攻击性相关的学习的新方面,如形成稳健的赢家效应。
In Drosophila, prior fighting experience influences the outcome of later contests: losing a fight increases the probability of losing second contests, thereby revealing “loser” effects that involve learning and memory. In these experiments, to generate and quantify the behavioral changes observed as consequences of losing fights, we developed a new behavioral arena that eliminates handling. We compared two commonly used fly handling procedures with this new chamber and demonstrated that handling influences aggressive behavior and prevents “loser” effect formation. In addition, we induced and observed novel aspects of learning associated with aggression such as the formation of robust winner effects.
