Electric fish produce fast frequency sweeps to communicate, called chirps. Here, I detected these chirps with a CNN-classifier on spectrograms that was trained on data I simulated.

Some neurons in thet zebrafish brain respond to movement direction. We recorded and analyzed the activity of these neurons and showed, that these cells probably rely on luminance alone to perceive motion.

Spectrogram
Some electric fish synchronously modulate their frequencies in duets. I detected these events using a custom covariance-based event detector on frequency estimates from spectrograms.
