Bird song systems: Evolution
This article presents the vocal and auditory pathways of vocal-learning birds and a hypothesis about their evolution. These pathways control the ability to produce learned song in the few groups of birds that have vocal ...
A Foxp2 Mutation Implicated in Human Speech Deficits Alters Sequencing of Ultrasonic Vocalizations in Adult Male Mice.
(Front Behav Neurosci, 2016)
Development of proficient spoken language skills is disrupted by mutations of the FOXP2 transcription factor. A heterozygous missense mutation in the KE family causes speech apraxia, involving difficulty producing words ...
Dopamine regulation of human speech and bird song: a critical review.
(Brain Lang, 2012-09)
To understand the neural basis of human speech control, extensive research has been done using a variety of methodologies in a range of experimental models. Nevertheless, several critical questions about learned vocal motor ...
Global View of the Functional Molecular Organization of the Avian Cerebrum: Mirror Images and Functional Columns
(JOURNAL OF COMPARATIVE NEUROLOGY, 2013-11)
Evolutionary genomics and adaptive evolution of the Hedgehog gene family (Shh, Ihh and Dhh) in vertebrates.
(PLoS One, 2014)
The Hedgehog (Hh) gene family codes for a class of secreted proteins composed of two active domains that act as signalling molecules during embryo development, namely for the development of the nervous and skeletal systems ...
Comparative genomics reveals insights into avian genome evolution and adaptation
Gene loss, adaptive evolution and the co-evolution of plumage coloration genes with opsins in birds.
(BMC Genomics, 2015-10-06)
BACKGROUND: The wide range of complex photic systems observed in birds exemplifies one of their key evolutionary adaptions, a well-developed visual system. However, genomic approaches have yet to be used to disentangle the ...
The Origin and Diversification of Birds.
(Curr Biol, 2015-10-05)
Birds are one of the most recognizable and diverse groups of modern vertebrates. Over the past two decades, a wealth of new fossil discoveries and phylogenetic and macroevolutionary studies has transformed our understanding ...
Olfactory Receptor Subgenomes Linked with Broad Ecological Adaptations in Sauropsida.
(Mol Biol Evol, 2015-11)
Olfactory receptors (ORs) govern a prime sensory function. Extant birds have distinct olfactory abilities, but the molecular mechanisms underlining diversification and specialization remain mostly unknown. We explored OR ...
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 ...
