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...

Inhibition and recurrent excitation in a computational model of sparse bursting in song nucleus HVC.

8 Jun 2009 The telencephalic premotor nucleus HVC is situated at a critical point in the pattern-generating premotor circuitry of oscine songbirds. A striking feature of HVC's premotor activity is that its projection neurons burst extremely sparsely. Here we ... Read more...

Wireless neural stimulation in freely behaving small animals.

20 Apr 2009 We introduce a novel wireless, low-power neural stimulation system for use in freely behaving animals. The system consists of an external transmitter and a miniature, implantable wireless receiver-stimulator. The implant uses a custom integrated ... 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.
