Modulation of perineuronal nets and parvalbumin with developmental song learning.

12 Oct 2009 Neural circuits and behavior are shaped during developmental phases of maximal plasticity known as sensitive or critical periods. Neural correlates of sensory critical periods have been identified, but their roles remain unclear. Factors that define ... Read more...

A comparison of reptilian and avian olfactory receptor gene repertoires: species-specific expansion of group gamma genes in birds.

19 Sep 2009 BACKGROUND: The detection of odorants is mediated by olfactory receptors (ORs). ORs are G-protein coupled receptors that form a remarkably large protein superfamily in vertebrate genomes. We used data that became available through recent sequencing ... Read more...

Factors limiting song acquisition in adult zebra finches.

13 Sep 2009 Song learning takes place in two separate or partially overlapping periods, a sensory phase in which a tutor song is memorized and a sensorimotor phase in which a copy of the model is produced. The stage of song development where song becomes stable ... Read more...
