Normally if you meet someone who has a mini-fridge filled with brains, your first thought is to call the police. But when that someone is Dr. Alysson Muotri, a professor at U.C. San Diego, your second thought is “do tell me more.”
Alysson is a researcher who is fascinated by the human brain. He is working on many levels to try and unlock its secrets and give us a deeper understanding of how our brains evolved and how they work.
One of the main focuses of his work is autism (he has a son on the autism spectrum) and he has found a way to see what is happening inside the cells affected by autism—work that is already leading to the possibility of new treatments.
As for those mini-brains in his lab? Those are brain organoids, clumps of neurons and other cells that resemble—on a rudimentary level—our brains. They are ideal tools for seeing how our brains are organized, how the different cells signal and interact with each other. He’s already sent some of these brain organoids into space.
Alysson talks about all of this, plus how our brains compare to those of Neanderthals, on the latest episode of our podcast, Talking ‘Bout (re)Generation.
It’s a fascinating conversation. Enjoy.
