Human Brain Loses Billions of Neurons in New Analysis
by Jennifer Welsh
The whole human race just got a little dumber: A new analysis of the number of neurons, those brain cells that transmit thoughts, in the human brain has come back with a staggeringly lower number than thought — 14 billion brain cells fewer, about the size of the babboon brain.
The highly quoted number of human brian cells, 100 billion, doesn’t stand up to actual experimental inquiry, Suzana Herculano-Houzel, an assistant professor at the Universidade Federal do Rio de Janeiro, told the Nature neuroscience podcast NeuroPod.
The work was performed on four human brains, ages 50, 51, 54 and 71, from men who donated their brains to science…
