Scientists Found a Hidden Switch in Your Brain That Could Reverse Memory Loss

The brain may lie at the biological center of our lived experience, but the scientific underpinnings of the brain—specifically, how it forms subjective consciousness—remain mysterious. Sadly, one truth is well-known: As we age, so does our brain. Because this all-important organ, filled with 86 billion neurons, forms our experience, dysregulation within the brain has outsized impacts on someone’s quality of life. As this study—and many studies before it—have clearly demonstrated, there is no singular cause of mental decline. But with each new study, scientists work toward a holistic picture of neurodegenerative decline as we age, and with that new perspective comes the hope of new therapies that could make cognitive decline a thing of the past.
