In Roald Dahl’s short story, William and Mary, William dies of cancer. But a novel procedure allows his brain, with one eye attached, to be kept functioning in a clear plastic vat. His wife convinces William’s neurosurgeon to allow her to take William (or rather his brain and eye) home with her.
When home, Mary places William in a prominent place in the sitting room from where he can survey all her actions. He had been a domineering and controlling husband. He forbade her to have a TV and to smoke. Now, Mary purchases a TV and takes up smoking, blowing smoke in the direction of William. She will punish him for his abuse and his brain may stay alive, utterly powerless, for up to 200 years.
This story was science fiction. But yesterday, the first step to creating the brain in a vat was reported in the US. Back in July 2013, scientists reported the first organ grown from stem cells: a liver. A kidney, heart and other organs have followed. The potential of these technologies to eventually provide replacement organs is also an opportunity to sweep away complex ethical issues: most obviously in avoiding the need for organ donation, but also in enhancing the ability to test drugs on lab grown organs before testing in humans- reducing the risk of harm to research participants, hopefully some day to a negligible amount.
Now, just 2 years later, the first brain has been grown in a laboratory. The organoid has been grown for 12 weeks, the equivalent of a 5 week old foetus.
