FoxP2 in songbirds.
Humans with mutations in the transcription factor FOXP2 display a severe speech disorder. Songbirds are a powerful model system to study FoxP2. Like humans, songbirds communicate via vocalizations that are imitatively learned during critical periods and this learning is influenced by social factors and relies on functionally lateralized neural circuits. During the past five years significant pr...
متن کاملLingual articulation in songbirds.
Lingual articulation in humans is one of the primary means of vocal tract resonance filtering that produces the characteristic vowel formants of speech. In songbirds, the function of the tongue in song has not been thoroughly examined, although recent research has identified the oropharyngeal-esophageal cavity as a resonance filter that is actively tuned to the frequency of the song. In norther...
متن کاملMolecular-based Studies in Songbirds
Expression mapping of activity-dependent genes has been very useful to reveal brain activation patterns associated with specific stimuli or behavioral contexts. In addition, activity-induced neuronal gene expression is likely associated with neuronal plasticity and may be part of the mechanism(s) involved in long-term memory formation. Analysis of the immediate-early gene zenk has been used to ...
متن کاملAuditory-vocal mirroring in songbirds.
Mirror neurons are theorized to serve as a neural substrate for spoken language in humans, but the existence and functions of auditory-vocal mirror neurons in the human brain remain largely matters of speculation. Songbirds resemble humans in their capacity for vocal learning and depend on their learned songs to facilitate courtship and individual recognition. Recent neurophysiological studies ...
متن کاملMitochondrial genomic rearrangements in songbirds.
The organization of the mitochondrial genome is generally very conserved among vertebrates. Because of this, examination of the rare rearrangements which do occur has been suggested as offering a powerful alternative to phylogenetic analyses of mitochondrial DNA sequences. Here, we report on an avian mitochondrial rearrangement in a group of oscine passerines (warblers of the genus Phylloscopus...
