A million people suffer from tinnitus -- in province of Quebec alone

Université de Montréal Professor Sylvie Hébert studies the condition

Université de Montréal Professor Sylvie Hébert is conducting a study exploring the root causes of tinnitus, a condition that creates the perception of sound in the absence of external stimulation. Tinnitus affects 20 percent of Quebecers 55 and older in Quebec, which represents one million people.

"The auditory sensations sound like buzzing or whistling in one or both ears," says Professor Hébert of the Université de Montréal's Faculty of Medicine School of Speech Therapy and Audiology and researcher at both the Institut universitaire de gériatrie de Montréal and the BRAMS.

"It is pretty hard to study because only the suffering patient can describe the intensity. In addition, tinnitus isn't observable with current clinical tools," says Hébert, noting the job may be difficult but not impossible and she has devised a two-part study.

The first part subjected more than 20 subjects to a variety of auditory perception tasks in order to measure the neural correlates of tinnitus using magnetic resonance imaging (MRI). The second part explored the physiological pathway. The objective is to study the correlation between stress and tinnitus and demonstrate the role of endocrinal processes in normal and abnormal auditory perception.

"Tinnitus can emerge after an ear infection, such as a poorly treated ear inflammation (otitis), sound trauma such as a gun shot or loud concert speakers, or hearing deterioration from aging known as presbycusis," says Hébert. "In certain cases, tinnitus could result from a disorder of the auditory nerve fibers, which would send auditory information to the central nervous system in the absence of prior stimulation."

Currently, no medication exists. However, according to Hébert, classic hearing aids that increase external sounds can help. Also, auditory prosthesis that create a sound comparable to a waterfall can help mask the buzzing and whistling of tinnitus.

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
