Would be quite a plot twist if it resulted that the whole "seizures cure" spiel from electroshock therapy, resulted in it being "electrical waves help the brain to clean itself", and have nothing to do with brain-destroying seizures.

The papers, all published in the journal Nature, suggest that during sleep, slow electrical waves push the fluid around cells from deep in the brain to its surface.

The new studies come more than a decade after Iliff and Dr. Maiken Nedergaard, a Danish scientist, first proposed that the clear fluids in and around the brain are part of a system to wash away waste products.

It turned out that the waves were acting as a signal, synchronizing the activity of neurons and transforming them into tiny pumps that push fluid toward the brain's surface, the team reported in February in the journal Nature.

In a second paper published in the same issue of Nature, a team led by scientists at the Massachusetts Institute of Technology provided more evidence that slow electrical waves help clear out waste.

In a paper published a few weeks earlier, Kipnis had shown how waste, including amyloid, appeared to be crossing the protective membrane that usually isolates the brain.

So finding ways to help the brain clean itself — perhaps by inducing those slow electrical waves — might prevent a wide array of disorders.

This just in: brain sleeve found filled with microplastics preventing washed amyloid fluid from draining.

Seriously though, this seems like a significant discovery!

RadioLab covered the dawning of the (serendipitous) discovery a few years ago called: "bringing back gamma".
