“More evolved” brains, not “better muscles”:
Neurobiologists at the University of Pittsburgh School of Medicine give new meaning to the term “motor mouth” in a study published today in the Proceedings of the National Academy of Sciences. By carefully mapping neural networks in marmoset and macaque monkeys, they determined that multiple areas in the brain’s frontal lobe control the muscles of vocalization and could provide a foundation for complex speech…
“This kind of parallel processing in our neural wiring might explain why humans are capable of highly sophisticated language that allows us to share information, express and perceive emotion, and tell memorable stories,” said Strick, who also is scientific director of Pitt’s Brain Institute. “Our remarkable speech skills are due to more evolved brains, not better muscles.” University of Pittsburgh, “Neuroscientists find multiple brain regions control speech, challenging common assumption” at Medical Xpress (May 4, 2022)
Sure. It has nothing to do with ideas.
The paper is open access.

Researchers: Investigators led by a team at Massachusetts General Hospital (MGH) that previously discovered tiny channels in the skull have now found that cerebrospinal fluid (also known as “brain water”) can exit the brain into the skull’s bone marrow through these channels.
