Mice as vocal learners?

Short notice: There’s a new paper out in PLoS ONE (Arriaga et al., 2012) about signatures of vocal learning in mice. The main evidence is from neurological data – activation of the motor cortex during vocalisations, among others – and from behavioural experiments demonstrating sensitivity to feedback, both from others – mice modify their vocalisations when put into novel groups – and auditory feedback about their own vocalisations: the song of deafened mice deteriorates over time.
