Two-photon imaging of mouse retinal boutons in superior colliculus

These data contain activity (in form of calcium traces) of single retinal axon terminals (boutons) imaged in the superior colliculus of mouse. Mice were able to run on a floating ball. Running speed and pupil size were recorded simultaneously. Mice were presented with full-field, drifting, sinusoidal gratings (“gratings”), uniform gray screens (“grayScreen”), darkness (“dark”), or black and white squares on gray background (“noise”).See Schröder et al. (2020) for details on methods (https://www.cell.com/neuron/fulltext/S0896-6273(20)30318-4).See boutons ALF definitions.pdf for detailed description of data.

本数据集包含在小鼠上丘（superior colliculus）中成像获得的单个视网膜轴突终末（突触小体，boutons）的活动数据，其表现形式为钙信号轨迹（calcium traces）。实验小鼠可在浮球上自主跑动，实验同时记录其奔跑速度与瞳孔大小。实验向小鼠施加了四类视觉刺激：全视野漂移正弦光栅（full-field drifting sinusoidal gratings，后文简称“gratings”）、均匀灰屏（uniform gray screens，后文简称“grayScreen”）、黑暗环境（darkness，后文简称“dark”）以及灰度背景上的黑白方块刺激（black and white squares on gray background，后文简称“noise”）。实验方法的详细细节可参考Schröder等人2020年的研究（链接：https://www.cell.com/neuron/fulltext/S0896-6273(20)30318-4）。数据集的详细说明可参见《boutons ALF definitions.pdf》文档。
