Abstract :
[en] Songbirds including zebra nches (Taeniopygia guttata) have been widely used as a model for studying vocal learning and the associated neural plasticity. Recently, two neural markers for critical periods in brain plasticity were suggested to be related to song learning
in males: parvalbumin (PV) expression would be associated with the onset of experience-dependent plasticity whereas perineuronal nets (PNN, chondroitin sulfate proteoglycans surrounding neurons) would limit potential plasticity at the end of sensitive phases
(Balmer et al., 2009). Here we explored sex differences in PNN in the zebra finch song system.
