Scientists grow 'human brains' in laboratory

The miniature brains are the size of a pea and will be used to aid research in to neurological disorders.
Known as cerebral organoids, the tiny brains were grown using a complex process beginning with embryonic stem cells or adult skin cells. Droplets of gel were used to provide a scaffolding for the tissue to grow when combined with a special nutrient solution.

Researchers believe that the organoids, complete with many of the same regions as a fully developed brain such as the cerebral cortex and hippocampus, offer them a fairly accurate representation for the brain of a nine-week-old fetus.

"What our organoids are good for is to model development of the brain and to study anything that causes a defect in development," said researcher Dr Juergen Knoblich. "Ultimately we would like to move towards more common disorders like schizophrenia or autism. They typically manifest themselves only in adults, but it has been shown that the underlying defects occur during the development of the brain."

if you took a child and left it in the wilderness with no human contact, the childs brain development is seriously messed up for a human that is. We have all heard tales of feral kids found in forests who cannot adapt to 'human' life very easy or communicate either. Now a brain, with no ears or eyes,or a body for physical stimulation, or even if it had eyes, wont be aware of itself as being a person, because its not. Nor will it have any learnings that may be construed as human either. So for people who get freaked out that its a 'human'.... really it isn't. Its human bra... [More]

This may be true. How could we know what's going on inside the brain? It might be self-aware without external stimulation. It might have pre-linguistic thoughts, intimations and intuitions even though it lives in isolation. It may develop a complex set of internal associations with meanings for itself. In fact, not experiencing external stimuli, these brains may come to conclusions impossible for us who have personalities. If we could link our brains to these brains, we might discover they have some valuable wisdom to teach us. I mean, how great is it to have a personality? Personaliti... [More]

Hmm, a brain without thought. So many political jokes here, so little time.......

Lol, Sundew. We were thinking the same thing.

Haha, some things are just too easy!

I guess growing organoids from cells will help scientists study or learn more about our own organs and one day help fight certain horrible diseases. But then again there's that eternal ethical question of where do we set the boundaries....and that fear of this technology falling in the wrong hands.

Great. Now they can mass produce them and surgically implant them in Congress critters. It would be a major step forward, a government that actually has a means to acquire intelligence. Edit to add: Yeah, I know it's been said in other words already but I just woke up and haven't yet started my 1st liter of coffee. Deal with it.

I think it's a great development. Now if they can just keep the politics out of it...

Yeah, we don't want politicians with brains. They may actually start thinking. There's a scary thought.
