Decoding from a reconstructed population of bORNs obtained by calcium imaging. a, Calcium signal of bORNs before and following stimulation with odorant pulses applied at 11.4 s and 31.4 s (blue vertical bars). Fluorescence intensity was filtered and z-scored. Up to six cells were simultaneously imaged. Each trial was then considered as an activity of an individual bORN. A total of 59 cells from 23 experiments were combined to form a virtual population of 400 bORNs. b, Population average of a. c, Likelihood spectrum for decoding the interstimulus interval (20 s). ML estimated interval is 21.18 s on the test set.
