❝ Xuyu Qian yanked open an incubator door at the University of Pennsylvania to reveal rows of cylindrical tubes swirling, like shaken-up snow globes, with a strange and exotic flurry. The pale, peppercorn-sized spheres were lab-grown globules of human brain tissue, or, as Qian occasionally refers to them, “minibrains.”
“Minibrain” is a controversial nickname, loathed by some scientists who fear it conjures alarmist images of fully functioning brains trapped in vats, while the reality today is balls of cells that can’t think or feel…
❝ …As the technology, which scientists refer to in journal articles as “cerebral organoids,” improves, the more the “minibrain” title fits…“People are more worried about if they reach a certain level — if it’s really like a human brain. We’re not there; we’re very far from there,” said Hongjun Song, who leads the laboratory at Penn’s Perelman School of Medicine, where Qian works. “But the question people ask is, ‘Do they have consciousness?’ The biggest problem I have so far is I think, as a field, we don’t know…”
