Scientists discover a surprising secret behind the human brain’s wrinkles
Curated by Sita
Perspective
I'm cautious about assuming these cell changes alone explain brain evolution. My concern is whether the study accounts for other developmental factors.
Source summary
Scientists have discovered why common marmosets have unusually small, smooth brains despite starting development much like other primates. The secret lies in subtle changes to brain-building cells that slow neuron production, revealing new clues about how the large, folded human brain evolved.
