A statistical method for quantifying songbird phonology and syntax.
9 Jul 2008 
Songbirds are the preeminent animal model for understanding how the brain encodes and produces learned vocalizations. Here, we report a new statistical method, the Kullback-Leibler (K-L) distance, for analyzing vocal change over time. First, we use ...

19 Jun 2008 Vocal communication is critical for successful social interactions among conspecifics, but little is known about how the brain regulates context-appropriate communication. The neurotransmitter dopamine (DA) is involved in modulating highly ...

Population coding of song element sequence in the Bengalese finch HVC.
30 May 2008 Birdsong is a complex vocalization composed of various song elements organized according to sequential rules. Two alternative views exist that explain the neural representation of song element sequences in the songbird brain. The finding of ...

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 ...

Functional identification of sensory mechanisms required for developmental song learning.
4 Apr 2008 A young male zebra finch (Taeniopygia guttata) learns to sing by copying the vocalizations of an older tutor in a process that parallels human speech acquisition. Brain pathways that control song production are well defined, but little is known ...

24 Mar 2008 Birdsong, like human speech, is a series of learned vocal gestures resulting from the coordination of vocal and respiratory brainstem networks under the control of the telencephalon. The song motor circuit includes premotor and motor cortical ...

Precise auditory-vocal mirroring in neurons for learned vocal communication.
15 Jan 2008 Brain mechanisms for communication must establish a correspondence between sensory and motor codes used to represent the signal. One idea is that this correspondence is established at the level of single neurons that are active when the individual ...

Catecholaminergic cell groups and vocal communication in male songbirds.
15 Dec 2007 Birdsong is a species-typical vocal signal that facilitates reproduction and deters competitors. Song production is regulated by a clearly defined and specialized neural circuitry in which high concentrations of catecholamines are present. The ...

12 Dec 2007 Testosterone (T) induces singing behavior and mediates changes in the sizes and neuroanatomical characteristics of brain regions controlling singing behavior (song control regions, SCRs) in songbirds. These effects may require the enzymatic ...
