This is one of a barrage of books developing out of the neurostudy of brains made possible by information accumulated through the use of new instruments and theories. One small factoid would stick to another, then some indications fit into that and a theory would form, which was tested by other instruments, in a process that Bor calls "chunking" but I like to call "clustering," the pattern for how atoms form elements and how elements form molecules which in turn form creatures. The form of the book is interesting: 274 pages of text, 31 pages of references, many of which are simply accounts of experiments and results, including some major landmarks which it is handy to have all on one list. Website url's are included in footnotes.kkk It's friendly writing, rather personal, quite clear, very well edited and nicely printed.
The two personal motors for Bor's work are his wife's struggle with bipolar disorder and, as he begins the book, his father's stroke which made one side of his brain silent. The research for much of this work, like a lot of medical categories including psychiatry, comes from dealing with disorders, lesions, genetic aberrations, with consequences that might be profoundly disturbing (a baby born with no cerebrum) or merely interesting (synesthesia, for since, hearing sounds in colors.) But it's not all gloom: his baby daughter makes a star appearance, full of joy and life as she develops in a protective and loving world.
The great value of the book for me is its order-creating, its pattern-making, its ability to show sequences and consider paradigms. Of course, this is also the book's theme -- that the brain is ravenous for such information which is the source of meaning.
