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...

Mesotocin and nonapeptide receptors promote estrildid flocking behavior.

12 Aug 2009 Proximate neural mechanisms that influence preferences for groups of a given size are almost wholly unknown. In the highly gregarious zebra finch (Estrildidae: Taeniopygia guttata), blockade of nonapeptide receptors by an oxytocin (OT) antagonist ... Read more...

A basal ganglia-forebrain circuit in the songbird biases motor output to avoid vocal errors.

11 Jul 2009 In songbirds, as in mammals, basal ganglia-forebrain circuits are necessary for the learning and production of complex motor behaviors; however, the precise role of these circuits remains unknown. It has recently been shown that a basal ... Read more...
