Vocal Cords News and Research

RSS

The vocal cords, are composed of twin infoldings of mucous membrane stretched horizontally across the larynx. They vibrate, modulating the flow of air being expelled from the lungs during phonation.

Biologists identify how and where the brain processes FM sweeps

In both animals and humans, vocal signals used for communication contain a wide array of different sounds that are determined by the vibrational frequencies of vocal cords. For example, the pitch of someone's voice, and how it changes as they are speaking, depends on a complex series of varying frequencies. Knowing how the brain sorts out these different frequencies-which are called frequency-modulated (FM) sweeps-is believed to be essential to understanding many hearing-related behaviors, like speech.

Pediatricians warn about hazards of button batteries

With the increasing production of electronic products in the consumer market, more button batteries are found in the home setting. From remote controls and watches to musical greeting cards and toys, these small, shiny objects are the perfect size for a curious child to swallow or even push into their nasal cavity or ear canal. It is important for parents to be aware of the dangers that button batteries pose to young children and the damage that these batteries can cause.

Brain 'talks' to computer by saying/thinking of a particular sound

Patients with a temporary surgical implant have used regions of the brain that control speech to "talk" to a computer for the first time, manipulating a cursor on a computer screen simply by saying or thinking of a particular sound.

Study investigates risk of dysphagia after radiotherapy treatment for head & neck cancer

At the 3rd International Conference on innovative approaches in Head and Neck Oncology (ICHNO), Dr Hanna Rahbek Mortensen and colleagues at hospitals and institutes in Denmark presented results from a large prospective trial, the DAHANCA 6 & 7 study. The study, conducted across the country, investigated risk factors for developing dysphagia (swallowing dysfunction), after undergoing radiotherapy treatment for a head & neck cancer.

Study on flavors of laughter

Most scientific research on laughter is based on recordings of people pretending to laugh. But for Michael Owren of Georgia State University in Atlanta, this false laughter -- the sound of a canned sit-com laugh track -- is a pale imitation of the real thing. He studies the full vocabulary of chortles, giggles, guffaws we all use in everyday situations.

UT Southwestern head and neck cancer surgeons perform area's first transoral robotic surgery

Head and neck cancer surgeons at UT Southwestern Medical Center performed the area's first transoral robotic surgery (TORS), a recently approved minimally invasive no-scar procedure to remove tumors in the throat.

Low frequency ultrasound can heal and regenerate body tissues

When we think of ultrasound, it's usually imaging the inside of the body that springs to mind. However, while ultrasound imaging typically requires frequencies that are 50 to 2500 times higher than those human ear can detect, recent increasing evidence indicates that ultrasound at lower frequency can also be used to help certain body tissues to heal and regenerate. Now research that appears in Open Access Journal of Tissue Engineering published by SAGE-Hindawi suggests that ultrasound could also help tissue grafts to survive and thrive following surgery.

Johns Hopkins doctor says sports events and cell phones can harm voice

From the first tip-off during March Madness to the championship’s final buzzer, and with start of the 2010 Major League Baseball season, on Sunday, April 4, thousands of people will relentlessly scream and shout, placing tremendous strain on their voices. While no one is recommending complete silence, the constant pressure on the vocal cords can cause great damage.

Study to understand acoustic communication across animal species

Scientists who compare insect chirps with ape calls may look like they are mixing aphids and orangutans, but researchers have found common denominators in the calls of hundreds of species of insects, birds, fish, frogs, lizards and mammals that can be predicted with simple mathematical models.

UC researchers receive $2.5 million grant to study treatment for voice disorders

For patients with severe voice disorders, the loss of their voice often means losing their social life, self esteem or livelihood. While existing therapies can treat mild to moderate voice disorders, physicians have a harder time determining effective treatments for those with severe cases.
