Immune cells gobble up idle brain cells

A type of immune cell has been found to demolish idle circuits and connections within the brain.

Scientists studying the process in an effort to learn more about degenerative brain diseases have found that brain connections that aren't used are at risk of being demolished by the immune cells even if they are healthy. Up until now the microglia cells were thought to only protect the brain from damage and disease.

"The idea they can clean up brain debris has been well established in studies of brain disease," said Beth Stevens. "But now, even without damage, we've found them to respond to subtle changes in synaptic function."

"Use it or lose it: a class of immune cell demolishes idle circuits and connections in the brain, even a healthy one."

We use our brains in many different ways, not only to 'think'. You use them when you smell, touch, hear, and see. You use them when you dream and when you day-dream. when you talk and read. I think when someone gets deaf or blind later in life, then these cells might destroy some of those unused braincells associated with these senses. But I don't think it's about using your brains like in learning math or a new language. Anyway, interesting article.

Don't cells died by millions each night for all of us? I presume those are not just idle, but also old and dysfunctional. Anyway the bottom line is that we don't understand how our brain works, in this study's result won"t likely help us much in this.
