Scientists say this tiny, flexible robot could reduce the need for invasive surgery by working as a mini 3D printer inside your body.
Yes, it has rings. But very faint (not continuous), so for a long time it was believed that there were none. On this image they are unusually clear, perhaps that has something to do with mr. Webb focusing on the infrared spectre.Woah ! Did it always have such a ring ???
Not necessarily. So far, as I understand the article, the signals are found in the cerebral cortex, which is a fairly recent development of the nervous system, and only mammals have it.And : Because brains are so much essential in living beings, this kind of signal functionality must've been developed relatively early in evolution history.
For all I know it may be found in older parts of the brain, eventually. But at the moment it has been found in the cortex, and that's a recently developed structure. I suppose there will be a lot of further studies based on this find.I see. Hm, I had thought that it would have been there earlier, so to say.
