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...

Rapid interhemispheric switching during vocal production in a songbird.

12 Oct 2008 To generate complex bilateral motor patterns such as those underlying birdsong, neural activity must be highly coordinated across the two cerebral hemispheres. However, it remains largely elusive how this coordination is achieved given that ... Read more...

Nest of origin predicts adult neuron addition rates in the vocal control system of the zebra finch.

19 Apr 2008 Neurogenesis and neuronal replacement in adulthood represent dramatic forms of plasticity that might serve as a substrate for behavioral flexibility. In songbirds, neurons are continually replaced in HVC (used as a proper name), a pre-motor region ... Read more...

Technical information about 'High Vocal Center'

Definition: Nucleus in the NEOSTRIATUM of bird brains that sends signals for song production and receives auditory input. In some adult SONGBIRDS, research has shown that the size of this nucleus changes seasonally and that it exhibits neurogenesis.
