Wired for Sound: a Small Fish’s Brain Illustrates How People and Other Vertebrates Produce Sounds

16.06.2011
Cornell University researchers have identified regions of a fish brain that reveal the basic circuitry for how humans and other vertebrates generate sound used for social communication.

In a study of midshipman fish, published online today (June 14) in Nature Communications, the researchers identified two distinct groups of neurons that independently control the duration and the frequency of sounds used for calling. While human speech and bird songs are far more complex than the grunts and hoots produced by some fish, the study provides a very basic wiring diagram of how the brain allows vertebrates to vocalize.

“If you can understand the simplest system, it provides a road map for understanding the fundamental working units in the central nervous system for how you build a vocal system,” said Andrew Bass, Cornell professor of neurobiology and behavior and senior author of the paper.

In a 2008 Science paper, Bass and colleagues identified this same region of the brain in larval midshipman fish, showing how it is present in the brains of other animals, including primates. This suggests that the vocal networks in all vertebrates evolved from an ancestrally shared brain area that originated in fishes.

“Studies like these allow us to trace the evolutionary history of the brain,” Bass said. “All animals, including humans, share many brain circuits for complex behaviors, including the use of sounds for social communication.”

Co-authors include lead author Boris Chagnaud, postdoctoral researcher in the Bass lab, and Robert Baker, a researcher at New York University’s Langone Medical Center; the authors collaborated at the Marine Biological Laboratory at Woods Hole, Mass. The study was funded by the Grass Foundation and National Institutes of Health.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
