Recordings of ~20,000 neurons from V1 in response to oriented stimuli

Recordings from Stringer et al, 2019, now including higher-order visual cortex. The code to reproduce the figures from the paper is here:https://github.com/MouseLand/stringer-et-al-2019Please 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.If you use these data in a paper, please cite the original research paper as well as this dataset using the figshare doi.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: 100ms presentation time4) local: localized to neural receptive fields (30 deg)5) static_biased: rotation drawn randomly from interval [43 47] degreesThe next stimulus sets are all drifting at 2Hz:6) gratings_drifting: drifting gratings7) gratings_low_contrast: 1/20 the full contrast8) gratings_noisy: low contrast and per-frame independent noiseAdded in revision9) sinusoidal gratings with randomized phases10) biased_V2: like #5 but in higher-order areas lateral to V1.<br><br>Note that the stimuli are triggered on the microscope frames, so a neuron is always sampled at the same offset from stimulus start times.
