Tiny, 3-D clusters of human brain cells grown in a petri dish are providing
hints about the origins of disorders like autism and epilepsy.
An experiment using these cell clusters - which are only about the size of
the head of a pin - found that a genetic mutation associated with both
autism and epilepsy kept developing cells from migrating normally from one
cluster of brain cells to another, researchers report in the journal Nature.
