Lab-Grown Brains Are Closer Now. Should They Have Rights?

A new neuroscience research area raises as much concern as excitement: growing mini “human brains” in a lab. The excitement is the prospect of better understanding and treatment of dementia, autism, and motor neuron disease (ALS). The concern is that they will become sentient, capable of feeling. Then what? Starting in 2008, researchers learned that they could coax human stem cells to self-organize into “brainlike structures with electrically active neurons.” Although the cell clusters behave, to some extent, like human embryos, they are not human embryos but skin cells from an adult. That limits the ethical conflict in that the research does not depend on the abortion industry. But ethical issues crop up anyway as groups of cells become more…
