Gender-Specific Brain Cells Have Just Been Discovered Inside The Brains of Mice

'The theologians say that the soul has no sex, but I wonder. I very much wonder.' (Coleridge)

This news item dated 18 October was brought to my attention by the Anglo-Swedish writer Pelle Neroth Taylor.
Male and female mouse brains could have significant differences that reach right down to the cellular level, according to a new discovery.

Based on a reading of their genetic activity, neurons in a part of the mouse nervous system responsible for aggression and mating behaviours appear to be chemically structured in subtle but distinctly different ways between the two sexes.

These findings haven't been tested in other mammal species as yet, so we can't read too much into them. But it's a fascinating study that warrants further investigation in the brains of other animals.
