The pallial basal ganglia pathway modulates the behaviorally driven gene expression of the motor pathway.
(Eur J Neurosci, 2007-04)
The discrete neural network for songbird vocal communication provides an effective
system to study neural mechanisms of learned motor behaviors in vertebrates. This
system consists of two pathways--a vocal motor pathway ...
Comparative genomics reveals insights into avian genome evolution and adaptation.
(Science, 2014-12-12)
Birds are the most species-rich class of tetrapod vertebrates and have wide relevance
across many research fields. We explored bird macroevolution using full genomes from
48 avian species representing all major extant clades. ...
Brain evolution by brain pathway duplication.
(Philos Trans R Soc Lond B Biol Sci, 2015-12-19)
Understanding the mechanisms of evolution of brain pathways for complex behaviours
is still in its infancy. Making further advances requires a deeper understanding of
brain homologies, novelties and analogies. It also requires ...
FoxP2 expression in avian vocal learners and non-learners.
(J Neurosci, 2004-03-31)
Most vertebrates communicate acoustically, but few, among them humans, dolphins and
whales, bats, and three orders of birds, learn this trait. FOXP2 is the first gene
linked to human speech and has been the target of positive ...
Corollary discharge circuits in the primate brain.
(Curr Opin Neurobiol, 2008-12)
Movements are necessary to engage the world, but every movement results in sensorimotor
ambiguity. Self-movements cause changes to sensory inflow as well as changes in the
positions of objects relative to motor effectors ...
A framework for integrating the songbird brain.
(J Comp Physiol A Neuroethol Sens Neural Behav Physiol, 2002-12)
Biological systems by default involve complex components with complex relationships.
To decipher how biological systems work, we assume that one needs to integrate information
over multiple levels of complexity. The songbird ...
Molecular mapping of brain areas involved in parrot vocal communication.
(J Comp Neurol, 2000-03-27)
Auditory and vocal regulation of gene expression occurs in separate discrete regions
of the songbird brain. Here we demonstrate that regulated gene expression also occurs
during vocal communication in a parrot, belonging ...
Selective expression of insulin-like growth factor II in the songbird brain.
(J Neurosci, 1997-09-15)
Neuronal replacement occurs in the forebrain of juvenile and adult songbirds. To address
the molecular processes that govern this replacement, we cloned the zebra finch insulin-like
growth factor II (IGF-II) cDNA, a factor ...
Behaviourally driven gene expression reveals song nuclei in hummingbird brain.
(Nature, 2000-08-10)
Hummingbirds have developed a wealth of intriguing features, such as backwards flight,
ultraviolet vision, extremely high metabolic rates, nocturnal hibernation, high brain-to-body
size ratio and a remarkable species-specific ...
Evaluating functional network inference using simulations of complex biological systems.
(Bioinformatics, 2002)
MOTIVATION: Although many network inference algorithms have been presented in the
bioinformatics literature, no suitable approach has been formulated for evaluating
their effectiveness at recovering models of complex biological ...
