We designed a head-mounted three-photon microscope for imaging deep cortical layer neuronal activity in a freely moving rat. Delivery of high-energy excitation pulses at 1,320 nm required both a hollow-core fiber whose transmission properties did not change with fiber movement and dispersion compensation. These developments enabled imaging at >1.1 mm below the cortical surface and stable imaging of layer 5 neuronal activity for >1 h in freely moving rats performing a range of behaviors.

三光子头戴式显微镜,用于在自由移动的大鼠中成像深层皮质。

我们设计了一个头戴式三光子显微镜,用于对自由运动大鼠的深层皮质神经元活动进行成像。在1,320 nm处传递高能激发脉冲既需要空心光纤,其传输特性也不会随光纤移动和色散补偿而改变。这些发展使得在执行一系列行为的自由移动大鼠中,在皮层表面以下> 1.1 mm处进行成像,并在第1层中稳定成像第5层神经元活性> 1 h。
