Calcium imaging data for "Equivariant neuronal populations enable simultaneous tuning and invariance"

This dataset contains 3 large-scale two-photon calcium imaging recordings from across multiple mouse visual cortical areas (layer 2/3) in response to rotated naturalistic images. The dataset is organized into 5 main folders.stimulistim_05-08-23.mat: File used for stimulus presentation.img: 2760 images (92 objects × 15 orientations × 2 views) at resolution 300 × 1200 pixels.db: Names of the 2760 images (suffix _left or _front).istim: 10,200 integers (1–2760) indicating which image was shown on each trial.retinotopyareas.npz: Standard mouse area boundaries used for aligning retinotopies.out: 10 entries, each describing the boundary points of mouse visual cortical areas.Areas of interest: PM (entry 1), AM (2), RL (4), LM (6), AL (7), LI (8), V1 (9).Additional files: Retinotopy data for the 3 recorded mice. Each has the following information.xy_pos: Spatial position of each recorded neuron.rf_xy_pos: Estimated receptive field (RF) position.area_assign: Integer index of the cortical area assignment.rf_cc_max: Pearson correlation between recorded and RF-fitted responses.05_18_2023, 05_30_2023, 05_31_2023Each folder contains a single .npz file with Suite2p pre-processed calcium imaging data, which include the following variables.Behavioral: run, pupil (spherical treadmill)Stimulus: istim (stimulus index)Recording: iplane (top or bottom imaging plane)Neuronal responses: spks (deconvolved activity), xpos (x-position in imaging plane), ypos (y-position in imaging plane), uspont (spontaneous PCs), mu (mean activity during prolonged gray screens), sd (standard deviation during prolonged gray screens).
