THE IDEA OF THE BRAIN: The Past and Future of Neuroscience, very readable treatment of the State of the Art in neuroscience



THE IDEA OF THE BRAIN: The Past and Future of Neuroscience
MATTHEW COBB

Basic Books
$32.00 hardcover, available now

Rating: 4* of five

The Publisher Says: A powerful examination of what we think we know about the brain and why—despite technological advances—the workings of our most essential organ remain a mystery.

For thousands of years, thinkers and scientists have tried to understand what the brain does. Yet, despite the astonishing discoveries of science, we still have only the vaguest idea of how the brain works.

In The Idea of the Brain, scientist and historian Matthew Cobb traces how our conception of the brain has evolved over the centuries. Although it might seem to be a story of ever-increasing knowledge of biology, Cobb shows how our ideas about the brain have been shaped by each era's most significant technologies. Today we might think the brain is like a supercomputer. In the past, it has been compared to a telegraph, a telephone exchange, or some kind of hydraulic system. What will we think the brain is like tomorrow, when new technology arises? The result is an essential read for anyone interested in the complex processes that drive science and the forces that have shaped our marvelous brains.

I RECEIVED A DRC FROM THE PUBLISHER VIA NETGALLEY. THANK YOU.

My Review
: The brain...the thing that is translating these geometric shapes on a screen into words, ideas, thoughts...is weirdly pulled apart and put together again in our age of tecnological marvels, yet lacking a paradigmatic metaphor. The many paradigms that we've fitted around our brains since we figured out the ancient system of thinking that had the heart at the center of intellect worked fine...until they broke trying to explain new data on brain function.

Well, you might think, so what? They're metaphors, not facts.

That's true as far as it goes. The role of a paradigmatic metaphor, like the best we have today of a supercomputer, isn't just to provide useful handles to grasp the still-elusive overarching explanation of what, how, and why the brain is and does. Thomas Kuhn, philosopher of science, said (in essence) that paradigms work until they don't and until new paradigms emerge, progress stalls.

That is where we stand now, atop a mountain of recently acquired data that blows up the supercomputer metaphor, but without another paradigmatic metaphor to shift to. We need, in short, another great leap forward like Darwin's theory of evolution was for millennia of accumulated biological data, to help us see how this immense pile of information can be turned into a fuller and more useful understanding of the brain and its processes.

While this is not the most fluffy and amusing read of 2023, it was deeply informative and very much an eye-opener. I had thought the neurologists were much farther behind the other sciences than they, in fact, are...much has been learned with the existence of fMRI machines and the technological like. The downside of these sorts of advances come when the private sector steps in to monetize the discoveries. They have no interest in helping people with the tech advances unless there's profit in it. The story of a severely epileptic woman whose life was completely changed by a brain implant being developed by a start-up, which then went bust, and the device (patent-protected) was permanently turned off, was particularly illustrative of the issue's costs.

Readable, informative, trenchant. Not easy to digest, but repays the effort put in with a very expanded view of whre science has come after its explosive beginnigs. Made me eager to see what comes next.

If, that is, I live that long...look how long it was between Linnaeus inventing the idea of species and Darwin explaining how they came to be in the first place.
