Legrenzi and Umiltas book deals with all of those colour photos of the brain,
that mass media inundates us with. Pictures that apparently show us the precise location in which a certain thought or emotion occurs in the brain.
Indeed, newspapers often carry articles that one area of the brain governs falling in love, resisting temptation etc. illustrated by a picture of a human brain with a colored section. The news article then explains that the coloured part becomes active when participants in an experiment see their loved ones etc.
But do the newspaper readers really understand the many steps that are needed to produce that picture of the brain with the coloured area? And that each step is based on assumptions, which are not always sound?
In the book, Legrenzi and Umilta takes us through some of the techniques involved, from fMRI scanning to ''cognitive subtraction''. And as the techniques are explained the assumptions also gets exposed.
Obviously, the brain still holds many secrets.
Brain science is not just: The discovery of a one to one connection between a cognitive state and the activation of a brain area. Thats not enough to say that a phenomenon has been revealed and the problem has been solved...
Obviously not. Really understanding, how the brain works, takes many more steps beyond establishing connections between cognitive states and activations.
Obviously, we shouldn't believe everything we read in the newspapers.
And the book certainly explains to us that we should be careful, when neuro images are presented to us.
A good place to start, as we venture further into the frontiers of brain-land.
