This dataset contains the fluorescence traces from calcium imaging. The data are provided in csv format, wherein the value represents relative fluorescent unit (⊿F/F) of neuron i (arranged in columns) at t-th frame (arranged in rows). The time resolution of the recording is 50 ms/frame. A journal paper is to be published in PNAS with full details of materials and methods. https://www.pnas.org/doi/abs/10.1073/pnas.2217008120 File naming convention ・"Spon.csv" is a data obtained in a spontaneous activity recording. ・The other file s are named according to the delivered stimulus. ・For the static pattern recognition task, "StimA", "StimB", and "StimC" correspond to the stimulation of the top, middle, and bottom regions in Figure 1B. ・"_half" and "_quarter" refers to stimulations with reduced areas, described in Figure S2A. ・For the speech recognition task, "f1" and "m1" represent the gender of the speakers, and "zero", "one", ... are spoken digits. ・"_reverse" refers to a stimulation to a temporally-reversed input.
