Slow-growing progenitor cells cause smooth brains in common marmosets
Most primate species have a relatively large brain with a surface marked by pronounced bulges and furrows. This is not the case with common marmosets (Callithrix jacchus). The brains of these small monkeys are smooth and virtually unfolded.

BIOENGINEER.ORGWhy Marmoset Brains Stay Smooth: Progenitor Cells Hold the Evolutionary Key
Researchers at the German Primate Center show that slower-dividing, structurally simpler, and temporally shifted neural progenitor cells explain why the common marmoset develops a small, smooth brain unlike the folded brains of most primates.
The brain of white bunny monkeys is unusually small and almost smooth for primates. Comparisons of brain organoids and fetal tissue now show that there is not a single mechanism behind it. Rather, certain neuronal precursors divide more slowly, later switch to other development programs and sometimes have simpler cell forms, resulting in fewer nerve cells. Göttingen (Germany). The cerebral cortex of many primates forms in the [...] Der Beitrag G…
