The Gendered Brain - Gina Rippon
I saw Professor Rippon give a talk about this book a few months ago, and have been itching to read it ever since.
It's a weighty tome - and deservedly so. It takes in the full history of neuroscience and attempts to understand whether men and women have different brains, different physical structures, and different abilities.
It is rigorous and compelling. Not exactly an easy read - and it feels like it tackles the same subjects repeatedly. But then again, the same old rubbish keeps popping up.
If you'd like to buy the hardback, I can recommend popping in to the Vagina Museum shop in London.
