Two-photon imaging of mouse retinal boutons in superior colliculus (.npy)

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.

本数据集包含在小鼠上丘（superior colliculus）中成像得到的单个视网膜轴突终末（突触小体，boutons）的活动信号，其记录形式为钙活动轨迹（calcium traces）。实验小鼠可在浮动球上自由跑动，实验过程中同步记录了小鼠的跑动速度与瞳孔尺寸。实验向小鼠呈现了多种视觉刺激范式：全视野漂移正弦光栅（"gratings"）、均匀灰色背景屏幕（"grayScreen"）、纯黑暗环境（"dark"），以及灰色背景上的黑白方块（"noise"）。具体实验方法细节可参考Schröder等人（2020）的研究成果。
