US brain project puts focus on ethics
The false mouse memories made the ethicists uneasy. By stimulating certain neurons in the hippocampus, Susumu Tonegawa and his colleagues caused mice to recall receiving foot shocks in a setting in which none had occurred1. Tonegawa, a neuroscientist at the Massachusetts Institute of Technology in Cambridge, says that he has no plans to ever implant false memories into humans — the study, published last month, was designed just to offer insight into memory formation.
But the experiment has nonetheless alarmed some neuroethicists. “That was a bell-ringer, the idea that you can manipulate the brain to control the mind,” says James Giordano, chief of neuroethics studies at Georgetown University in Washington DC. He says that the study is one of many raising ethical concerns, and more are sure to come as an ambitious, multi-year US effort to parse the human brain gets under way.
