Overloaded, by Ginny Smith (Bloomsbury, 325 pages)
Science writer Ginny Smith’s Overloaded, while not the most sparkling prose you’ll read this year, does a yeoman’s job at explaining, in understandable language, the workings of the brain and what controls it. Mindfulness has its place, but in fact, our thoughts, emotions and memories are the sum of what Smith calls “a turbulent sea of neurotransmitters.” And sea is not just a figure of speech. “It seems to me that the answer lies not in the wiring of our brains, but in the chemicals that bathe them,” Smith writes.
Smith starts by assuming that we have forgotten everything we learned in high school and teaching a sort of CliffsNotes class in Neurology 101: the differences between sensory and motor neurons, the duties of the synapse, how electrical signals flow. Along the way, like a good professor, she introduces some interesting people, such as Luigi Galvani, the Italian scientist who figured out how to make the legs of dead frogs twitch (inspiration for Mary Shelley’s Frankenstein), and two European scientists who shared the Nobel Prize in 2006 even though each disagreed with the other’s work. (Nice to know that even Nobel Prize winners can bicker like crows.)
From there Smith delves into eight typical areas of interest regarding the brain: memories, motivation, mood swings and fear, sleep, hunger and satiation, decision-making, love and attraction, and pain.
In the chapter on memory she darts from treatments for PTSD to imprinting in ducklings to the long-term effects on the neglected children in Romanian orphanages. It’s a skillfully woven collection of stories, but unfortunately, offers no significant or surprising information on how to maintain our own memory.
The chapter on motivation delves into research on primates and mice and does a good job of explaining how dopamine works and why its effects decline over time. Again, however, the chapter held more promise than it delivered. Any real-life application might have to do with drug or alcohol withdrawal, not how to get motivated to exercise or clean the house.
By “Mood Swings and Scary Things,” I’m on to the pattern. Smith dangles an interesting topic in front of me — sharks! — and then swims away. After a quick dip in the mechanics of the fear response, she’s suddenly musing about the moods of a childhood tortoiseshell cat. And on it goes.
By the time we come to sleep, which Smith considers the brain’s greatest mystery, I’ve given up on getting any practical application for my life, and I’m only here for the anecdotes. Admittedly, they are good, such as the story of a strange illness that spread throughout Vienna in 1916 and came to be known simply as “sleepy sickness.” (People would feel generally unwell at the start, and then, as the illness progressed, spend more and more time asleep. Eventually they fell into a coma and died, basically sleeping themselves to death.)
The illness killed about one million people over 10 years and eventually disappeared, and there still is no consensus on the cause, although it must have had something to do with hypothalamus, which is the part of the brain that controls sleepiness and wakefulness.
Here, too, we finally get to Alzheimer’s disease, and theories about sleep deprivation might be connected, since during sleep, a sort of rinse cycle of the brain sweeps out waste that is believed to be involved in the development of dementia.
By now we know that in “Food for Thought” we’re not going to get any dieting tips. In fact, unhelpfully, Smith even writes, “There is currently only one really effective treatment for obesity: bariatric (or weight loss) surgery.” Also, she confides that when she is quite reasonably attracted to the pastry tray at a breakfast buffet, she deals with temptation by: filling her plate with fruit and yogurt. At this point, she reveals herself to be some freak of nature, sort of like the aliens in suits in Men in Black, so she has diminished cred in the ensuing discussion on eating disorders.
Finally, you’ve probably heard of St. Elmo’s fire, but how about St. Anthony’s fire? That’s another strange disease, this time in medieval France, in which poor people were afflicted with severe pain in the extremities. (Eat the rich — they never got it.) It turns out that the people were getting sick from a fungus that grew in the rye used in bread and beer. Even stranger, this discovery eventually led to a substance that is much more familiar today — oxytocin.
Overloaded suffers from an overload of English spelling (Smith teaches at the University of Cambridge), an overload of the author’s personal anecdotes and, most egregiously, an overload of exclamation marks. It won’t be the best book you read this year; in fact, let’s hope it’s the worst. But it’s a serviceable summer read for the intellectually curious. C
