2. Brain size - Wikipedia

   en.wikipedia.org/wiki/Brain_size

   The size of the brain is a frequent topic of study within the fields of anatomy, biological anthropology, animal science and evolution.Measuring brain size and cranial capacity is relevant both to humans and other animals, and can be done by weight or volume via MRI scans, by skull volume, or by neuroimaging intelligence testing.

   In modern humans, cranial capacity can vary by as much as 1000 cc, without any correlation to behavior. This degree of variation is almost equivalent to the total increase in volume from australopithecine fossils to modern humans, and brings into question the validity of relying on cranial capacity as a measurement of sophistication.

   The advent of MRI as a non-invasive highly-accurate measure of living brain structure and function (using fMRI) made this the pre-dominant and preferred method for measuring brain volume. [1] Overall, larger brain size and volume is associated with better cognitive functioning and higher intelligence. [1]

   Taking short, daytime naps might also give your brain a boost. One of Garfield’s studies showed that people who napped regularly had, on average, larger brain volume than those who didn’t.

   Diets that were high in sodium, which one study defined as greater than 12,000 milligrams (or 2.1 teaspoons) per day, were linked to lower cognitive function and a 330% increase in the risk of ...

7. Expensive tissue hypothesis - Wikipedia

   en.wikipedia.org/wiki/Expensive_Tissue_Hypothesis

   The expensive tissue hypothesis (ETH) relates brain and gut size in evolution (specifically in human evolution).It suggests that in order for an organism to evolve a large brain without a significant increase in basal metabolic rate (as seen in humans), the organism must use less energy on other expensive tissues; the paper introducing the ETH suggests that in humans, this was achieved by ...
