where it is used to assess the performance of spike deconvolution algorithms. The code repository to reproduce the analyses in the paper is uploaded at


We recorded ~10,000 neurons simultaneously at 2.5Hz using calcium imaging. Visual stimuli were shown at approximately 1 Hz, with randomized inter-stimulus intervals. The stimuli were drifting gratings with 8 directions, 4 spatial frequencies and 3 temporal frequencies. Blank stimuli (gray screen) were also interleaved.
