Through a combination of gene therapy, eyeglass cameras, and visual cortex implantation, partial restoration of vision in those suffering from disorders such as age-related macular degeneration (AMD) may become a reality.
Researchers are attempting to bypass the damaged retina and create new photo-receptors in the visual cortex (through gene therapy). These new photo-receptors would receive stimulation through an implant powered by induction coils, similar to those found in cochlear implants.
The visual cortex implant receives its information through a pair of glasses equipped with cameras tracking eye position and what is in the person’s line of site. These glass would be similar to the body or ear-level processors of modern cochlear implants.
While clinical application is still a few years away, the future of vision implants is certainly bright.

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. …
Memorizing Movements: How Tai Chi Can Improve Balance and Cognition
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)….
Skyquakes—Did You Hear It?
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…
