A research group argues that a species’ number of neurons, rather than brain volume, should serve as indicator of cognitive capacity when studying brain evolution, but some experts voice doubts.

Dampwood termites with the potential to leave the colony have larger optic lobes before ever being exposed to different visual environments, an example of predictive brain plasticity.
An analysis of the contours of more than 600 kids’ brains points to links between cerebral surface area and heritability in regions of the brain important in cognition.
Authors of a new study suggest that 520-million-year-old structures, previously identified as the brains of ancient arthropods, are instead preserved microbial biofilms.
