Why? Because evolution made some pretty hefty tradeoffs in energy cost, soft/fractured skulls at birth, etc. in order to scale the human brain. As a consequence, we have perhaps ~1 quadrillion synapses (https://t.co/chwik7apTO). 2/

What people are saying
Discussions consistently emphasize that neuron number, rather than brain size, underpins intelligence, exemplified by phrases like 'neuron quantity is key' and 'primates scale linearly,' with tone ranging from analytical to skeptical, reflecting a deep exploration of the article’s implications.
Most discussions support the idea that neuron quantity and primate scaling laws are key to understanding brain function, showing general consensus with some skepticism about size as a sole indicator.
Posts highlight a high level of curiosity, referencing detailed research and emphasizing the significance of the findings, indicating strong interest.
Many posts delve into scientific debates about neuron counts, energy efficiency, and evolutionary tradeoffs, demonstrating deep engagement with the topic.
While some posts praise the findings for advancing neuroscience understanding, others suggest skepticism about the overemphasis on size, leading to a moderate impact perception.
Abstract in brief
- Recent research shows that brain size alone does not determine the number of neurons, as different scaling rules apply across species, making the human brain similar in cell composition to other primates of its size.
- The human brain contains about 80% of its neurons in areas other than the cerebral cortex, similar to other mammals, challenging the idea that an overdeveloped cortex makes humans uniquely intelligent.
- While the human brain isn't exceptional in cellular composition, it is built efficiently following primate scaling rules, making it the largest among primates and giving it the highest number of neurons, emphasizing that cognitive abilities may depend more on total neuron count than body size or brain size alone.]

Amazing research of @suzanahh from 2009, showing evidence that the real advantage of humans over other primates is the sheer number of neurons in their brains. Not the size, not the share of body mass, maybe even not the brain architecture. https://t.co/uvpVdijPxC

This article should receive even more buzz. It argues that brain size, relative size and body size are irrelevant to computational ability, and that primate brains are uniquely compact among the brains analyzed to date (2009). That neuron quantity is key. https://t.co/KccvhEwgzS
Also, my 2009 review in Frontiers has been seen over 300k times, and cited well over 1,000k. People frown at Frontiers, but fact is, papers there can get LOTS of attention very fast. I have no problem with that. Sometimes a paper just needs to be seen. https://t.co/FRvkw8c0je

Primate brains scale up their number of neurons linearly with size… But all other mammals species don’t (neurons basically get bigger)! A human-sized mouse would still have many times less neurons than a human, or a chimpanzee https://t.co/9EfYiaa6h0
"(…) a generic rodent brain of human-sized proportions, weighing 1.5 kg: such a brain would have only 12 billion neurons (…) This number of neurons is smaller than the number of neurons estimated to exist in the human cerebral cortex alone (…)" https://t.co/9EfYiaa6h0 https://t.co/slg1ZrwipS
