Please use the "issues" section from this repository for all communications regarding this dataset.
Each npy file is one recording of deconvolved fluorescence traces + all its metadata, with the name of the file indicating the stimulus set.
Each stimulus set is a single image/movie, with each trial rotating that stimulus by a random angle between 0 and 360. Unless otherwise specified, the stimuli cover 90 degrees of visual field at 0.05 cycles/degree and are shown for 750ms, with ~1000ms in-between. This ISI is fixed and determined by the recording rate which changes slightly from dataset to dataset.
1) gratings_static: square static gratings.
2) minnie: complex stimulus (cartoon mouse head).
3) gratings_short: 200ms presentation time
4) local: localized to neural receptive fields (30 deg)
5) static_biased: rotation drawn randomly from interval [43 47] degrees
The next stimulus sets are all drifting at 2Hz:
6) gratings_drifting: drifting gratings
7) gratings_low_contrast: 1/20 the full contrast
8) gratings_noisy: low contrast and per-frame independent noise
Note that the stimuli are triggered on the microscope frames, so a neuron is always sampled at the same offset from stimulus start times.
