In humans and several other mammals, brain cells are distributed according to a fundamental mathematical pattern, which could help researchers make better models of the brain in the future.
The density of neurons in the brain is governed by a fundamental mathematical function, new research finds.
Morales-Gregorio and his colleague Alexander van Meegen, a postdoctoral researcher at Harvard University, led the new study, which was published in July in the journal Cerebral Cortex. During their attempts to build models of the brain, van Meegan told Live Science, the team realized scientists knew little about what dictated the density of neurons in the brain.
"If we only look at the mean number of neurons, maybe one doesn't see the difference," van Meegen said. But the long-tailed distribution means that a few changes to extreme outliers in density might make a big difference in brain connectivity or even function.
