Simply hearing the song produced by another bird of the same species triggers the regulation of microRNAs (miRNAs) in high-order auditory parts of the zebra finch brain. Some of the identified miRNAs appear to be unique to birds, possibly to songbirds. These findings, reported in BMC Genomics, highlight the complexities of gene regulation associated with vocal communication and point to possible key regulators of song-triggered gene networks.
