Since the beginning of the COVID-19 pandemic, there have been reports in the professional literature on possible hearing loss caused by the disease. A new study from Tel Aviv University (TAU), in collaboration with the Galilee Medical Center, finds no evidence of damage to the auditory system as a result of COVID-19 infection.
“Our study explored whether COVID-19 can cause permanent neural or sensory damage to the hearing system. We found no evidence for such damage,” says co-author Dr. Amiel Dror of the Galilee Medical Center and the Azrieli Faculty of Medicine at Bar-Ilan University. “We measured electrical data from the brainstem to test the entire route of soundwaves through the ear until electric waves are ultimately received in the brain. We also examined the activity of the inner ear hair cells that intensify and tune the sound. We found no difference between the COVID-19-positive subjects and the control group.”
This study examined asymptomatic patients, but these researchers are currently conducting a much more comprehensive study with hundreds of patients, including persons who had been severely ill and even ventilated.

“Huh?” is used in at least 31 languages around the world! A version of the word can be found in nearly every language on Earth (Dingemanse et al, 2013). This research concluded that all languages studied included a word similar, in both sound and function, to the English “huh?” Regardless of language, the word is…
If you have a dog or cat, you’ve probably seen their ears moving toward an interesting or startling sound. For professional equestrians, watching the ears of their horse allows them to gauge their shifting attention. Humans still have these same muscles, and even more interesting is their relationship to our brain and how we pay attention. …
Tai Chi is not just for increasing balance; it may also help improve cognitive performance. In a recent randomized controlled trial, study participants who practiced a form of Tai Chi twice a week for six months improved their scores on the Montreal Cognitive Assessment (MoCA) when compared to a control group (Fuzhong et al, 2023)….
