New publication titled "Characterization of the vocal behavior of the miniature and transparent fish model, Danionella cerebrum" at The Journal of the Acoustical Society of America.
Danionella cerebrum is a promising model for studying the adult vertebrate brain, particularly vocal-auditory neural pathways. We analyzed its acoustic repertoire, finding high vocal activity with short bursts of pulses and longer sounds. Vocal activity peaked at midday, decreasing significantly at night. The number of pulses was higher during the day, with longer intervals between pulses at night. Vocalization duration was positively correlated with viable egg numbers, suggesting acoustic communication's importance in reproduction. These findings demonstrate D. cerebrum's potential for studying vocal flexibility and its role in sexual selection and reproduction in neuroscience.
