Newly found circuit through visual cortex powers first look at faces
The superior colliculus, an evolutionarily ancient brain area responsible for eye movements, responds to faces before the canonical face areas do, a study of macaque monkeys suggests.

Monkey studies throw wrench into decade-old idea about movement’s effect on visual cortex
Movements that boost activity in the visual cortex of mice have the opposite or no effect in marmosets and macaques, prompting questions about whether mice are a suitable model for the primate visual system.

Method pinpoints cell-specific effects of autism-linked mutations
The approach, which combines CRISPR with single-cell analyses of organoids, suggests that intermediate progenitor cells are especially vulnerable to mutations associated with autism.
