The Ethics of Experimenting with Human Brain Tissues

Difficult questions will be raised as models of the human brain get closer to replicating its functions, explain Nita A. Farahany, Henry T. Greely and 15 colleagues.

If researchers could create brain tissue in the laboratory that might appear to have conscious experiences or subjective phenomenal states, would that tissue deserve any of the protections routinely given to human or animal research subjects?

This question might seem outlandish. Certainly, today’s experimental models are far from having such capabilities. But various models are now being developed to better understand the human brain, including miniaturized, simplified versions of brain tissue grown in a dish from stem cells — brain organoids1,2. And advances keep being made.

A Tiny Microscope Can Now Record a Mouse's Brain in Real Time

Using a tiny microscope outfitted with some special gear, scientists have built a tool that can track the millions of interactions among brain cells in a mouse’s head. Hopefully one day, this technology could be applied to the human mind to help better understand conditions like autism and schizophrenia.
