At Mind Matters News: Human, mouse, and fly brains all use the same basic mechanisms

The study of brains in recent decades has yielded a very different picture from the patterns we might have expected:

A new study led by researchers from King’s College London has shown that humans, mice and flies share the same fundamental genetic mechanisms that regulate the formation and function of brain areas involved in attention and movement control.

We might have expected a gradual increase in size and complexity, corresponding with ability, leading up to the human brain. But we have learned from recent research that lemurs, with brains 1/200 the size of chimps’, pass same IQ test (the Primate Cognition Test Battery). Human intellectual abilities are orders of magnitude greater than that of any other life form, with no proportionate increase in size.

Why pioneer neurosurgeon Wilder Penfield said the mind is more than the brain. He gave three lines of reasoning, based on brain surgery on over a thousand patients.

This shouldn't have been overly surprising. Blue whales have vastly larger brains than humans but have about the same IQ as dogs and cats. Size is just one variable. polistra
