LONG, SLOW BURN
Regarding Ulrich Kraft's “Burned Out”: Herbert J. Freudenberger may have coined the term “burnout syndrome” in the 1970s, but he was not the first to notice the phenomenon. In The Wealth of Nations in 1776, Adam Smith observed that many people could only work at full output for a small number of years and that it was the bosses' job “rather to moderate, than to animate” their workers. George Combe in 1827 wrote that work must be enjoyable, which it could not be if it was too hard or too long: otherwise the only happiness is retirement.
Early in the 20th century the Yerkes-Dodson Law related increasing stress and motivation to an inverted U-shaped curve for work output; at the highest level of stress, output dropped to zero. Behavioral researcher B. F. Skinner discussed how a bricklayer could “burn himself out” in 1953. He called it “abulia,” or absence of behavior, and described it as the consequence of too much work being expected.
An old Scottish proverb puts it in a nutshell: “The hired horse never tires.” This expression implies that the hirer's attitude can cause work woes. Competition and the profit motive seem to be at the root of the problem in an industrial society.
“Burned Out” was right on target with the observation by Juergen Staedt that recognizing effort motivates high performers by rewarding them for their extra stress. One need only look at the cycle of outsourcing to see how employees at all levels feel compelled to increase their productivity, further contributing to their stress. When the organizational ax falls in spite of their efforts, as Staedt notes, they take an even harder hit.
The remedies mentioned do work well, and a stable relationship and supportive spouse are essential. I identify with their subjects: at age 50, I switched careers from graphic production to teaching. It was stressful, but friends and family were supportive, and that made the difference.
An enlightening book on this subject is Professional Suicide: A Survival Kit for You and Your Job, by Donald W. Cole (McGraw-Hill, 1981). Cole, a consultant, investigated why promising employees with symptoms resembling burnout would commit “professional suicide” by leaving for lesser jobs or remaining on staff but “retiring.” He blamed a corporate culture with vague goals, which penalized the best employees and allowed the less able to work it to their advantage. Upper managers would usually terminate his services when he reported that the problem was not with the employees but with them.

BRAIN CELL CHATTER
“Beyond the Neuron Doctrine,” by R. Douglas Fields, sheds new light on the old debate on how neurons communicate. We agree with him that more scientific work needs to be done before answering the question: How are waves so well coordinated in the human brain? One interesting research area focuses on the question: How are physics and human information processing linked? Perhaps in future research, we can look at quantum physics to come to a more basic understanding of the mechanisms behind neuron communication, and as a result we might come to a better understanding of the human brain.

A collision between biology and physics sparked the science of electrophysiology the day Luigi Galvani touched bare metal forceps to a skinned frog leg and it twitched with life. Alessandro Volta dismissed Galvani's 1791 startling discovery of “animal electricity” as an electrochemical reaction between metal and salty body fluids, an argument that led him to discover the chemical battery. Human brain waves were not seen until 1929, by an obscure German psychiatrist, Hans Berger, who was searching for a physical basis for mental function.
From our first glimpse of them to today, brain waves seem complicated, puzzling and difficult to analyze. They have been viewed from one extreme to the other: dismissed as an epiphenomenon—like the sound of an engine, a consequence of its operation but of no functional significance—and conjured as the imagined physical basis for mental telepathy. Unlike the easily comprehended messenger function of the nerve impulse, brain waves are not taught or understood by most neurobiologists. The complicated signals are revealed only with specialized equipment and sophisticated computers. Today the most advanced mathematics and physics are applied to analyze brain waves: Fourier analysis, power spectra, coherence measurements, vector analysis, eigenvalues, wavelet analysis, coupled oscillator dynamics—most of which are outside the expertise of biologists. Brain waves fascinate us, because their violent electrical storm shifts in complex ways with the winds of our mental state and move with the currents of our thoughts.
After reading “Beyond the Neuron Doctrine,” I have a question: Is there a significant difference in the power spectrum of brain-wave activity among humans with different brain-related disorders? For example, do children who are mentally disabled or autistic have significant differences in the power spectrum of their brain waves (which I assume are measured by EEGs) compared with those of “normal” children?
FIELDS REPLIES: Yes, readings of brain waves are being applied in early diagnosis of sensory and cognitive impairments—and not just in infants. Brain waves evoked by test stimuli allow doctors to diagnose deafness in newborns, and EEGs are useful in evaluating some forms of mental retardation in children, such as Angelman's syndrome. They also are being used experimentally to detect attention-deficit hyperactivity disorder (ADHD), schizophrenia and—before symptoms are even apparent—mild cognitive impairments in the elderly caused by Alzheimer's.
The fascinating article on “Controlling Epilepsy,” by Christian Hoppe, gives me the self-confidence to report that I suffered epilepsy-type seizures for 21 years until a wonderful neurosurgeon performed an operation that gave me back a normal life. It is a pleasure for me to talk about this because I had to experience what others are suffering through in controlling epilepsy: there is hope!

My 19-year-old daughter was diagnosed with epilepsy at the age of 12. Your article gave me more knowledge and a deeper understanding of the surgical procedure and tests that go along with it. For that, I thank you.
But I cringed when I read the words “grand mal” not once but twice. Do you know that the expression means “big evil”? Using it perpetuates the religious interpretation of the condition that you discussed: that those who endure epilepsy are receiving God's punishment or are influenced by the work of demons. Use the proper terminology: “tonic-clonic.”
