SELF COMES TO MIND

CONSTRUCTING THE CONSCIOUS BRAIN

Damasio (Director/Univ. of Southern California Brain and Creativity Inst.; Looking for Spinoza: Joy, Sorrow, and the Feeling Brain, 2003, etc.) seeks to understand “the mystery of consciousness.”

“Consciousness is a state of mind in which there is knowledge of one’s own existence and of the existence of surroundings”—i.e., where the self introduces the property of subjectivity to the mix. The mind emerges as it composes patterns, “mapping” the world as it interacts with it, just as it maps its own processes. It will appropriate the sensory experiences and make them its own. “Ultimately consciousness allows us to perceive maps as images,” writes Damasio, “to manipulate those images, and to apply reasoning to them.” The author entertains the unconventional idea that mind processing begins at the brain-stem level, not in the cerebral cortex alone, and charts the interaction of the brain stem, the cerebral cortex and the thalamus, taking elementary mind processes through to imagination, reasoning and eventually language. He provides a well-rendered explanation for the role of consciousness in the natural selection of evolution by meeting an organism’s needs through orientation and organization. Along the way, Damasio confronts such slippery characters as feelings, emotions, the will to prevail, biological value and homeostasis, and he also looks carefully at neuroanatomical reference. Consciousness, in the author’s well-tempered and rangy explication, “resembles the execution of a symphony of Mahlerian proportions. But the marvel…is that the score and the conductor become reality only as life unfolds.” And its many players are responsible for everything from internal housekeeping to “placing the self in an evanescent here and now, between a thoroughly lived past and an anticipated future, perpetually buffeted between the spent yesterdays and the tomorrows that are nothing but possibilities.”

Awareness may be mostly mystery, but Damasio shapes its hints and glimmerings into an imaginative, informed narrative.

A SHORT HISTORY OF NEARLY EVERYTHING

Bryson (I'm a Stranger Here Myself, 1999, etc.), a man who knows how to track down an explanation and make it confess, asks the hard questions of science—e.g., how did things get to be the way they are?—and, when possible, provides answers.

As he once went about making English intelligible, Bryson now attempts the same with the great moments of science, both the ideas themselves and their genesis, to resounding success. Piqued by his own ignorance on these matters, he’s egged on even more so by the people who’ve figured out—or think they’ve figured out—such things as what is in the center of the Earth. So he goes exploring, in the library and in company with scientists at work today, to get a grip on a range of topics from subatomic particles to cosmology. The aim is to deliver reports on these subjects in terms anyone can understand, and for the most part, it works. The most difficult is the nonintuitive material—time as part of space, say, or proteins inventing themselves spontaneously, without direction—and the quantum leaps unusual minds have made: as J.B.S. Haldane once put it, “The universe is not only queerer than we suppose; it is queerer than we can suppose.” Mostly, though, Bryson renders clear the evolution of continental drift, atomic structure, singularity, the extinction of the dinosaur, and a mighty host of other subjects in self-contained chapters that can be taken at a bite, rather than read wholesale. He delivers the human-interest angle on the scientists, and he keeps the reader laughing and willing to forge ahead, even over their heads: the human body, for instance, harboring enough energy “to explode with the force of thirty very large hydrogen bombs, assuming you knew how to liberate it and really wished to make a point.”

Loads of good explaining, with reminders, time and again, of how much remains unknown, neatly putting the death of science into perspective.

THE GENIUS OF BIRDS

Science writer Ackerman (Ah-Choo!: The Uncommon Life of Your Common Cold, 2010, etc.) looks at the new science surrounding avian intelligence.

The takeaway: calling someone a birdbrain is a compliment. And in any event, as Ackerman observes early on, “intelligence is a slippery concept, even in our own species, tricky to define and tricky to measure.” Is a bird that uses a rock to break open a clamshell the mental equivalent of a tool-using primate? Perhaps that’s the wrong question, for birds are so unlike humans that “it’s difficult for us to fully appreciate their mental capabilities,” given that they’re really just small, feathered dinosaurs who inhabit a wholly different world from our once-arboreal and now terrestrial one. Crows and other corvids have gotten all the good publicity related to bird intelligence in recent years, but Ackerman, who does allow that some birds are brighter than others, points favorably to the much-despised pigeon as an animal that “can remember hundreds of different objects for long periods of time, discriminate between different painting styles, and figure out where it’s going, even when displaced from familiar territory by hundreds of miles.” Not bad for a critter best known for bespattering statues in public parks. Ackerman travels far afield to places such as Barbados and New Caledonia to study such matters as memory, communication, and decision-making, the last largely based on visual cues—though, as she notes, birds also draw ably on other senses, including smell, which in turn opens up insight onto “a weird evolutionary paradox that scientists have puzzled over for more than a decade”—a matter of the geometry of, yes, the bird brain.

Ackerman writes with a light but assured touch, her prose rich in fact but economical in delivering it. Fans of birds in all their diversity will want to read this one.
