This is how Deaf people’s brains process visual rhythms

The brain has a remarkable ability to respond to change – to the extent of reorganizing itself after a traumatic injury or a sensory disability, as well as enabling the nervous system to adjust to the loss of an entire set of sensory inputs.

Evidence that brain circuits can be ‘re-purposed’ was recently reported in a study published in the Proceedings of the National Academy of Sciences of the United States of America (PNAS).

Researchers found that Deaf people had the same auditory processing regions in their brains activated when they interpreted visual rhythms from a flashing light, as when normal hearing people listened to the rhythms.

Study: 1 in 4 adults in U.S. may have hearing loss

A new report, published earlier this month in the US, has analyzed the most recent available data to determine how common noise-induced hearing loss is in adults aged 20 to 69. What they’ve found is quite staggering.

If you live in the US and are aged between 20 and 69, and struggle to understand speech in noisy environments, such as bars, cafés and restaurants, then it’s possible that you are one of the 25 percent of US citizens affected by noise-induced hearing loss.

How does conductive hearing loss affect the brain?

Have you ever had temporary hearing loss, possibly caused by an ear infection or a build-up of wax, which has affected your hearing?

According to a new study, “Even short-term blockages in hearing can lead to remarkable changes in the auditory system, altering the behavior and structure of nerve cells that relay information from the ear to the brain.”

The research into what happened when mice experienced temporary conductive hearing loss over a period of three days to over a week were published in the Journal of Neuroscience.

Aging Brains, Not Ears, May Cause Hearing Difficulties

The reason you may have to say something twice when talking to older family members at Thanksgiving dinner may not be because of their ears.

New research suggests older people’s difficulty hearing speech in loud noise may actually be because of something that is going on in their brains, rather than their ears.

Researchers at the University of Maryland have determined that older adults whose hearing would be ‘considered normal in a clinical assessment’ struggled to follow speech in a noisy environment – and more so than their 18-30-year-old counterparts, according to Journal of Neurophysiology.

Study: Gene to ‘turn off’ Tinnitus found

Researchers in Sweden have discovered a gene that may be used to prevent tinnitus, according to Science Daily

Researchers studied a ‘glutamate transporter’– a protein that removes glutamate where neural communication occurs – to determine how it is connected to tinnitus, and other problems such as seizures. 

By identifing the molecules behind tinnitus, researchers see it as a first step toward finding a treatment to silence the phantom noises.

Study: Risky listening habits causing tinnitus in teens

It’s common for teens to engage in risky behaviour, but one common activity may result in the loss of their hearing in the future.

According to new research, an alarming number of young people are experiencing tinnitus from being exposed to loud music.

Tinnitus, the persistent ringing, buzzing, or whistling in ears, is often a sign of early hearing damage. It is not only unpleasant, but can also lead to severe problems like depression or anxiety.

Study: Antioxidants could delay genetic hearing loss

Taking vitamins and antioxidants may help prevent genetic hearing loss in children, according to new research.

The researchers studied mice with a connexin 26 gene deletion – a common gene associated with hearing loss. The mice who had a diet full of beta carotene (precursor to vitamin A), vitamins C and E and magnesium had a slowed progression of hereditary deafness.

Can multi-tasking cause momentary deafness?

Have you ever been accused of having ‘selective hearing’ or ‘selective deafness’ – people saying that you can hear them when you want to, but not when you don’t? Well, there could be a scientific explanation for this, apparently and it’s called ‘inattentional deafness’.

According to a recent article published by Huffpostscience, “A new study has found that focusing really hard can cause momentary deafness.”  The article went on to say, “A small study from University College London, published in The Journal of Neuroscience, found that focusing on a visual task can make you momentarily deaf to normal-level sounds around you.” During the study, participants were asked to take part in a visual task involving deciphering ambiguous-looking letters whilst the researchers conducted brain scans on them.
