Cross-section of miniature human brains termed cerebral organoids
Miniature "human brains" have been grown in a lab in a feat scientists hope will transform the understanding of neurological disorders.
The pea-sized structures reached the same level of development as in a nine-week-old foetus, but are incapable of thought.
The study, published in the journal Nature, has already been used to gain insight into rare diseases.
Neuroscientists have described the findings as astounding and fascinating.
The human brain is one of the most complicated structures in the universe.
Scientists at Institute of Molecular Biotechnology of the Austrian Academy of Sciences have now reproduced some of the earliest stages of the organ's development in the laboratory.Brain bath
They used either embryonic stem cells or adult skin cells to produce the part of an embryo that develops into the brain and spinal cord - the neuroectoderm.
This was placed in tiny droplets of gel to give a scaffold for the tissue to grow and was placed into a spinning bioreactor, a nutrient bath that supplies nutrients and oxygen.
The cells were able to grow and organise themselves into separate regions of the brain, such as the cerebral cortex, the retina, and, rarely, an early hippocampus, which would be heavily involved in memory in a fully developed adult brain.
The researchers are confident that this closely, but far from perfectly, matches brain development in a foetus until the nine week stage.
The tissues reached their maximum size, about 4mm (0.1in), after two months.
The "mini-brains" have survived for nearly a year, but did not grow any larger. There is no blood supply, just brain tissue, so nutrients and oxygen cannot penetrate into the middle of the brain-like structure.

A cerebral organoid - the brown pigments are a developing retina
So that’s where they are coming from...
democrats .... reproducing ..... ??
Test tube democrats? No the brain is too big for a democrat.
This is great news for the US government. They’re into acquiring miniature brains in any way they can.
Now that I've got that out of my system - thanks for posting - interesting reading.

How do the cells survive without oxygen?
Has anyone from acorn registered that thing to vote yet?
Maybe Al gore could upgrade to this one.
“Miniature ‘human brain’ grown in lab”
If Obama had a son he would grow up in a lab.
I have ethical questions. People were given electric shock treatment, lobotomies.
Will seniors be subjected to "experimentation" because of alzheimers?? since they are deemed "worthless" in our sick society....just like babies in the womb....
Let's just kill them all. Obama thinks it's okay.
It’s not a human brain.
But watch. The tabloids will be saying “scientists grow human brain in laboratory”
So they are liberals.
Old news. The White House has been doing this for five years.
Post of the Day. You win, you were first.
The size of a pea? Already it is more advanced than that of DIMs/LIBs.
No. Because it has a brain, no matter how small it is.
Give it to Joe Biden,it has to be better than what he’s working with now.
It’s a good brain! Not Abby normal.
It is only the size of a pea. I don’t believe we have red blood cells in our brain. It is grey matter. search for blood brain barrier (keeps lots of stuff OUT of the brain) and visit here:
Simply as possible, the brain only receives molecules thru the barrier and WATER is the most important fluid cause it is broken down. Our bodies work at the molecular level. Keep hydrated!
I love neuroscience. And logically, if at 9 weeks and before they are growing SECTIONS of brain-—IT IS NOT JUST A BLOB OF TISSUE!
I am not yelling at you. I am yelling at the world through tears.
There is hope for DUmmieland.
Quite true, particularly for one “BrainDamaged” individual of recent note .... Perhaps a cranial injection of such cells could provide *some* benefit ??
Oxygen can diffuse between the cells for a couple millimeters. No cell can be any further from the surface than that and live.
That's why the growth stops at 4mm.
Next step, a circulatory system, then The Brain From Planet Arous.
I hope it has a Fissure of Rolando...
Dope o' mine.
Fissure of Rolando? I know a Tony of Orlando............
How do they know?
