Brain Rules

[SIDENOTE: Strangely, anytime, but only when this blogger writes something controversial, or about Donald Trump, WordPress crashes. Just an observation.]

The Book of the Week is “Brain Rules” by John Medina, published in 2008.

The author wrote about various factors that affect brain function, and how the brain can function better with regard to exercise, evolutionary developments, memory, driving, sleep, stress, the senses and gender.

The author claimed that studies have shown that any amount of exercise is better for the brain and body as a whole than no exercise at all. Intelligence can be maximized in work and school environments when people have a knowledge-base plus creativity. Other research showed that a simple experience of magazine-reading changed the neurons in the brain of one identical twin but not the other twin who hadn’t done magazine-reading.

Medina related a few anecdotes from his personal life to illustrate his points. A memorable incident for him occurred when a dog came out of a lake and shook water all over him. During those ten seconds, a normal human brain would “…recruit[s] hundreds of different brain regions and coordinate[s] the electrical activity of millions of neurons.”

The author cited blind gender studies in which subjects were asked their opinions of a person’s behavior; subjects held negative opinions of the person they were told was female, and positive opinions when told the person was male.

Medina crowed about how awesome retention was when research subjects were subjected to multi-sensory presentations (such as academic lectures, as when visuals, written text and verbal communication were used) as opposed to any of these alone.  He advocated minimizing the reading by subjects of large chunks of text because tests showed that it was not as effective at getting subjects to retain information as was multi-media.

It appeared that the author was promoting dumbed-down education in general; perhaps because it is in the best interest of any university professor to tow his employer’s line (and possibly the government’s) in order to continue to receive research grants and further his or her career.

Read the book to learn of more neurological studies and the author’s ideas (which he admits are fantasies) that might improve cognitive functioning at work or school.

Diary of a West Point Cadet

The Book of the Week is “Diary of a West Point Cadet” by Captain Preston Pysh, published in 2011. This slim volume tells of a West Point student’s experiences as a member of the Class of 2003.

Pysh (rhymes with “fish”) was originally from a small farm town in Pennsylvania. He was a growth-oriented, goal-oriented individual who survived the military-style draconian training meted out at the academy because he understood the lessons behind the rigor. The place had a demanding, exacting atmosphere– forcing the students to find creative solutions to problems in serving the upperclassmen. Only about one tenth of the students majored in electrical, mechanical or civil engineering. The author was passionate about aerospace engineering. The highlight of his college career was his senior project– an experimental device for NASA that he and his project-group members tested in a KC-135 aircraft.

Read the book to learn more about Pysh’s trials, tribulations and triumphs in navigating the high pressure, military-career oriented institution that is West Point.

Side Note: This book appears to have been written: a) with the aid of speech-recognition software (which has yet to be perfected) or b) simply never edited after the first draft, as it contained an annoying number of misspellings, skipped words and grammatical errors.

Genius on the Edge – Bonus Post

This blogger skimmed “Genius on the Edge” by Gerald Imber, MD, published in  2010. This long book describes the career of Dr. William Halsted.

Halsted was born in 1852 in New York City. There was still much ignorance about medicine in his generation. Fatal diseases, such as malaria, yellow fever and tuberculosis were rampant. He developed a passion for medicine at Yale University. The most prominent doctors of his age included Pasteur, Lister, Morse, Hunter, Wells, Koch, Morton, Young and Warren. They spurred progress in sanitation, anaesthesia, and the collection of new information and techniques for treating patients.

In the 1870’s, Columbia College, Physicians and Surgeons didn’t require undergraduate degrees for entry because it was seeking revenue from student tuition. The three-year program was all lectures– no labs, no interaction with patients. In the 1870’s, during Halsted’s internship at Bellevue Hospital, many personnel didn’t wash their hands before operating, and smoked.

In late 1884, Halsted started using cocaine as a local anaesthetic in dentistry. He displayed, “…hyperactivity, rambling speech, inattention, and suspended decision-making ability.” Medical students and their teachers started using cocaine as a pick-me-up. They became addicted. “The drug was readily available in Europe, through Merck, and there was no stigma associated with its purchase.” In late 1886, Halsted went to work at Johns Hopkins Pathological– the “Bell Labs” of medicine. He went to Baltimore because his addiction had wrecked his career in New York. He substituted morphine for cocaine.

It is unclear how much better Halsted could have performed were it not for his addiction. He did have a brilliant career, but there were bouts of irresponsibility, socially and teaching-wise. He missed classes, started surgery at 10am instead of 8 after a while, failed to show up for meetings, and retreated to his country home for almost half the year. One positive side effect of his addiction was that Halsted delegated complete patient care to residents when he had morphine withdrawal symptoms. So the residents got a golden opportunity they would not have had otherwise, to learn their craft.

Side Note (There’s nothing new under the sun.): “As a group, they [nurses] felt themselves underpaid and overworked.” The Training School taught them to cook and clean. They were required to wear brown Oxford shoes.

Halsted experimented on dogs on and off for a couple of years, between months-long stints in drug rehab. He began seeing human patients for surgery in early 1889. He pioneered the medical-school residency program. He instituted the training of surgeons to train other surgeons. Three other doctors at Johns Hopkins who wrought major change in medicine in the U.S. were William Osler, William Welch, and Howard Kelly. Halsted specialized in surgery for breast cancer and inguinal hernia.

Johns Hopkins wanted to remain on the cutting edge of medicine by opening a medical school but it needed money to do so. Female heirs of prominent, wealthy families raised the money and placed conditions on the school’s opening, requiring gender equality. After much controversy, it opened in the fall of 1893.

Read the book to learn how medicine in America changed through the years of the late 19th into the 20th century, and how, according to this book, Johns Hopkins led the way.

A Balcony in Nepal – Bonus Post

This blogger skimmed “A Balcony in Nepal” by Sally Wendkos Olds, art by Margaret Roche. This book is comprised of journal entries of a few trips to Nepal in the 1990’s and 2000 made by Olds and Roche. They met people in Kathmandu and the rural village of Badel, where they stayed.

At the airport, they were greeted by street urchins, eager to carry their luggage for tips. There were sacred cows lying in the middle of the road intersections, temples, motorcycles, taxis, rickshaws, young men offering hashish, Tibetan rugs, currency exchange and guide services. In Nepal, there is cronyism in employment, so the educated Nepalis with no connections are compelled to leave the country to seek a living elsewhere.

Teachers receive extremely low pay in Nepal because there is a casual attitude toward education. Families tend to be large, and older siblings must take care of the younger ones, and also work in the fields at the expense of school attendance. Thus, a low value is placed on literacy in the lower castes, such as Darje (untouchables), which includes blacksmiths, tailors, ferrymen, musicians and leatherworkers. The educated classes begin studying English in the fourth grade. They must buy their own books and writing instruments. The vast majority of teachers are men. They might skip school to work in the fields, too.

Medical care is handled in the rural villages by shamans (medicine men). A medical doctor is seven days’ walk and a two-day bike ride from Badel. When a villager’s ankle became swollen possibly from too much hiking, the village shaman told the patient his ankle hurt because he crossed the river without praying to the river god. So the shaman chanted over the ankle and told him to go pray by the river. The ankle got better in two days; perhaps via the placebo effect.

Wendkos and Olds engaged in some philanthropic activity by raising money to build a library in Badel. They attended the local political meeting at which a committee was formed for library-related planning. The attendees included all of Badel’s ethnic groups, Rai, Bhujil, Puri, Giri, Sherpa and Darje. Several years later, by 2000, the library had opened; however, it was being used to house a school rather than lend books.

Read this book to learn other aspects of Nepali culture, and the diarists’ thoughts and feelings on their experiences.
