Artificial neurons could replace lost or damaged brain cells

December 4, 2019

An international team of researchers has developed artificial neurons that could be implanted in the brain to repair the damage caused by Alzheimer’s disease and other neurodegenerative conditions.

The silicon chips, which behave like biological neurons, only need 140 nanoWatts of power. That’s one billionth of the power required by the microprocessors that have been used in other attempts to make synthetic neurons, making the silicon chips well-suited to being used as medical implants or inside other bioelectronic devices.
