Nachum Ulanovsky is a neuroscientist who works with bats. He wants to understand how brains navigate. With tiny implants and wireless data loggers he can watch neurons fire while bats fly. Find out more in this Nature Video.
Northwestern University and Washington University School of Medicine researchers have developed the first example of a bioelectronic medicine: an implantable, biodegradable wireless device that speeds nerve regeneration and improves healing of a damaged nerve. Their device delivered pulses of electricity to damaged nerves in rats after a surgical repair process, accelerating the regrowth of nerves and enhancing the recovery of muscle strength and control. The device is the size of a dime and the thickness of a sheet of paper and dissolves in the body after about two weeks.
