Head size parts autism into two major subtypes
An imbalance in the number of excitatory neurons in early brain development may account for the difference.

Organoids show how mutations in top autism gene may lead to brain overgrowth in people
The loss of CHD8, a top autism gene, speeds up the production of certain neurons and leads to overgrowth in spheres of cultured brain cells.

Worms help untangle brain structure/function mystery
The synaptic connectome of most animals bears little resemblance to functional brain maps, but it can still predict neuronal activity, according to two preprints that tackle the puzzle in C. elegans.
