果蝇的大脑显示出多个时间尺度的动态变化,从毫秒范围的快速电压或钙瞬变到多天内发生的功能和结构变化。要将这种动态与行为联系起来,需要在多个时间尺度上监测行为动物的神经回路。在这里,我们开发了一种技术,可以对果蝇进行自动长期双光子成像,在清醒和睡眠期间,在虚拟现实中导航长达 7 天。该方法是通过激光手术、用于控制解剖辅助镊子的微型机械臂、自动喂食机器人以及体积同步多平面成像来实现的。该方法在果蝇的头部方向系统中得到了验证。对果蝇在多个时间尺度上的行为进行成像将有助于了解昼夜节律活动、学习和长期记忆或睡眠。
The brain of Drosophila shows dynamics at multiple timescales, from the millisecond range of fast voltage or calcium transients to functional and structural changes occurring over multiple days. To relate such dynamics to behavior requires monitoring neural circuits across these multiple timescales in behaving animals. Here, we develop a technique for automated long-term two-photon imaging in fruit flies, during wakefulness and sleep, navigating in virtual reality over up to seven days. The method is enabled by laser surgery, a microrobotic arm for controlling forceps for dissection assistance, an automated feeding robot, as well as volumetric, simultaneous multiplane imaging. The approach is validated in the fly’s head direction system. Imaging in behaving flies over multiple timescales will be useful for understanding circadian activity, learning and long-term memory, or sleep.
