Mini-Brains Grown from Stem Cells Don’t Think, But They Do Show ‘Complex’ Neural Activity, Research Say

June 28, 2019

(CNN) – Floating disembodied conscious brains that issue commands to luckless human minions may be a cliché of science fiction, but they are a far cry from the primitive, lab-grown “cerebral organoids” that real scientists study today. New research suggests that contemporary mini-brains — even if inferior to their fictional counterparts — are still capable of a surprise or two. Evidence of dynamic activity, in individual and synchronized neurons, was seen across a network of cerebral organoids grown from stem cells in a preliminary study published Thursday in the journal Stem Cell Reports.
