Tomahawk, a rock band that Patton started in 2001 with former members of the Jesus Lizard, Helmet, and the Melvins, creates an off-kilter, genre-blending metal that showcases Patton's unhinged yet controlled vocals ("singing" is not always an adequate description).
Researchers operated on male and female birds, cutting the nerves that control vocal muscles in the syrinx.
VocalTractLab is capable of generating a full range of speech sounds by controlling vocal tract shapes, aerodynamics, and voice quality [27 29].
Based on the above findings and related studies, we propose the following theory: Cerebral systems that control vocal learning in distantly related animals evolved as specializations of a pre-existing motor system inherited from their common ancestor that controls movement, and perhaps motor learning.
This study is the first global mapping that we are aware for movement-associated areas of the avian cerebrum and it indicates that brain systems that control vocal learning in distantly related birds are directly adjacent to brain systems involved in movement control.
Several lines of evidence suggest that K-Channel genes may play important roles in controlling vocal production and learning in songbirds.
The zebra finch, a songbird, presents a unique opportunity to address this question because production of learned song and induction of vocal variability are instantiated in distinct circuits that converge on a motor cortex analogue controlling vocal output.
We controlled for vocal frequency variability, pitch accuracy, rhythmicity, syllable duration, phonetic complexity and other relevant factors, such as learning effects or the acoustic setting.
Song learning is known to exist in humans, dolphins, songbirds and parrots, but the new research overthrows a 50-year assumption that mouse vocalizing is inborn and instead shows that mice have a rudimentary vocal system to control their vocal cords and learn new tunes.
