A recent gif image has been circulating where individual can report hearing a “thud” sound with the image, despite there being no sound. The convergence of visual and auditory events is not new and researchers believe that the visually-evoked auditory responses (VEAR) are more common than previously thought.
Other types of synaesthesias are estimated to have an overall prevalence of 4.4 percent; however, recent work published in the journal Cortex estimated the prevalence of VEAR to 21 percent. To do so the researchers carried out a large-scale online study (n=4128) with a survey that included 24 silent video clips similar to the “thud gif.” They observed that those reporting “yes” to hearing sounds were more likely to report tinnitus or musical imagery.

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)….
The majority of people are familiar with earthquakes, but there is another phenomenon that is not nearly as predictable, and louder—skyquakes. Skyquakes are enigmatic sounds, typically described as a very loud boom or trumpet-sounding noise that has no apparent cause and seems to come from the sky. Their sound is like distant, but very loud, thunder with…
