In this dataset, we are sharing a time series of of electric pulses from dyads of freely moving Gymnotus sp. Because both fish are completely free to swim, the challenge is to detect which pulses were discharged by each of the fish. A rich repertoire of electrical behaviors can be observed, such as (i) offs (moments of silence) and (ii) chirps (small and noisy oscillations). This dataset was used in two of our most recent papers (see below).
