How personalized brain organoids could help us demystify disorders

Clumps of brain cells made from people with Rett syndrome had abnormal electrical activity

3-D brain organoids grown in the lab

Three-dimensional brain organoids grown in the lab, such as this one (shown), can be used to study how human brains work, and how that process can go awry in conditions such as Rett syndrome, a new study suggests.

Clumps of brain cells grown from the stem cells of two people with a neurological syndrome show signs of the disorder.
