Neurotosh, Neurodosh and Neurodash

Neurotosh. The best word from the entire Montreal Critical Neurosciences conference! There was Cordelia Fine, capturing perfectly her frustration at the manipulation of data and science in the service of stereotypes. Just pure neuro-nonsense.

The neurotosh in question was Louann Brizendine’s The Female Brain, an excellent representative of the neurosexism sold in recent popular books. It is popular, a bestseller translated into many languages, and it is simply bad science. In Nature Rebecca Young and Evan Balaban describe the book as “dressing the [gender] myth up in new clothes” and selling a “melodrama,” noting that “The Female Brain disappointingly fails to meet even the most basic standards of scientific accuracy and balance.”

Cordelia Fine took us step-by-step through several passages, examining the supposed citations and supporting evidence. Gender differences were confirmed by (a) studies with only women, (b) studies on a different topic entirely, and (c) personal communication. Ouch.

Plenty of other people have gotten on the bash-Brizendine-bandwagon, helping to undermine the moral authority that Dr. Brizendine wields through her academic credentials and “scientific” claims. Language Log has several critical analyses of the gender difference claims about language (see here, here and here). Mother Jones takes Brizendine to task on her approach to medicine. The most popular Amazon reviews of the book lead with titles calling The Female Brain “disappointing” and “nonsensical.” Vaughan Bell at Mind Hacks gets in on the pile-on-party as well.

Still Simon Cohn, a British anthropologist at the meeting, was rather nonplussed at Cordelia’s agonizing over the data and methods and claims made by Brizendine. As Simon said to me, “It’s called ‘The Female Brain.’ Doesn’t that tell you everything right from the start?” His point was that knowledge gets turned in the service of ideology and profit and power all the time.

Fall prevention in older people — Stephen Lord at HCSNet

Sway meter, subject on foam
Sway meter, subject on foam
Daniel isn’t the only guy at Neuroanthropology who gets to go to good conferences; last week, while in the throes of a cold brought on by fieldwork with the 15-and-under Sydney city select rugby team, I got to go to the HCSNet Workshop on Speech, Perception and Action held at Western Sydney University.

HCSNet is funded by the Australian Research Council to promote research on human communication. I only got to go to the second day of the two-day conference (because I was cooking meals for 20 hungry rugby hopefuls the first day), but I saw a number of great presentations, including talks by Catherine Best, MARCS Auditory Laboratories, UWS, Beatriz Calvo-Merino, University College London, and Stephen Lord, Prince of Wales Medical Research Institute. I’ll blog soon on Dr. Calvo-Merino, one of the high points of the day, but today I want to make some notes on Prof. Lord’s fascinating research and talk.

Prof. Lord heads the Falls and Balance Research Group. Visit the group’s website for publications and some great information about risk factors for falling. At the conference, Lord discussed the group’s extensive applied research examining different factors that contribute to older people falling and experimental interventions to decrease the contribution of any single factor. The project has created a screening procedure for use by general practitioners to evaluate an older person’s likelihood of falling.

As regular readers know, I’m particularly interested in the way humans maintain equilibrium (see earlier posts, Kids falling down and Equilibrium, modularity, and training the brain-body, and Daniel’s post of some great parkour video, Free Running and Extreme Balance). In the longer of these posts (Equilbrium, modularity…), I specifically discussed how the ‘sense of balance’ is actually a much more complex synthesis of multiple sensory inputs, both exteroception (perception of the world) and interoception (perception of the self).

When Pink Ribbons Are No Comfort: On Humor and Breast Cancer

By Casey Bouskill and Daniel Lende

In June, Jan Hoffman of the New York Times wrote “When Thumbs Up Is No Comfort,” reflecting on Ted Kennedy’s diagnosis with cancer and the ways in which the public obliges cancer patients to remain hopeful and strong while they ‘battle’ the ubiquitous and relentless disease.

Senator Kennedy presented an unfailingly upbeat attitude throughout his bout with a brain tumor, aided by such media images of him flashing a ‘thumbs-up’ to a crowd after a recent sailing race.

“Whether you’re a celebrity or an ordinary person, it’s obligatory, no matter how badly you’re feeling about it, to display optimism publicly,” said Dr. Barron H. Lerner, the author of “When Illness Goes Public.”

That optimism reassures anxious relatives, the public and doctors, regardless of whether it accurately reflects the patient’s emotional state. “If Ted Kennedy wanted to stick up his middle finger,” Dr. Lerner added, “that would be the more appropriate finger, but he’s doing what he is supposed to.”

Our ethnographic research with breast cancer patients here in South Bend, Indiana suggests that women are also fighting back against this so-called tyranny of optimism. Not by flashing the middle finger but by laughing!

Ostensibly, this humor seems to reflect that patients are cheerful and hopeful, just as the public obliges for women ‘battling’ breast cancer. But after thirty interviews and multiple participant observation sessions, we discovered that the use of humor among breast cancer patients extends far deeper. Essentially it is a covert rejection of these cheerful expectations ascribed to breast cancer patients.

In fact, these ‘bad gals’ of breast cancer described how personalized and often crude humor, relating to everything from hair loss to hot flashes to breast reconstruction, is a proud way of asserting one’s individuality and personality. It also forces others to acknowledge that cancer is a painful reality, and one that deserves recognition.

Breast cancer patients arguably have to deal with the expectation of cheeriness more than any other group. For the last fifteen years, it has been virtually impossible not to drive a car, enter a supermarket, or live through the month of October without feeling entangled in a web of pink ribbons. The arsenal of the pink ribbon acts as the unanimous symbol of support, as unwavering as the marches and speeches that go along with it. And this pink ribbon campaign consistently portrays the image of a middle-aged, white, beautiful woman whose life has been tragically put on hiatus while she valiantly fights the disease.

Somewhere between the ribbons on yogurt lids and rear bumpers of cars, society has lost touch with the reality of breast cancer and who suffers from it. In the United States breast cancer is affecting women (and men!) of all races, ages, socioeconomic statuses, and sexual orientations, leaving the many who do not fit the pink ribbon mold to have to reassert their personal identities and disavow themselves from society’s false pretenses.

How does humor act to reverse this growing trend?

Live healthy, turn on your genes

For all those out there who still think that ‘it’s all in the genes,’ here’s a recent news story on the way that changes in lifestyle can affect genetic activity. Will Dunham at ABC News brings us, Healthy Lifestyle Triggers Genetic Changes: Study (I also pulled it off the Reuters feed). The study was small, and I doubt that it was nearly as rigorous as really necessary, but the findings are interesting.

In a small study, the researchers tracked 30 men with low-risk prostate cancer who decided against conventional medical treatment such as surgery and radiation or hormone therapy.

The men underwent three months of major lifestyle changes, including eating a diet rich in fruits, vegetables, whole grains, legumes and soy products, moderate exercise such as walking for half an hour a day, and an hour of daily stress management methods such as meditation.

As expected, they lost weight, lowered their blood pressure and saw other health improvements. But the researchers found more profound changes when they compared prostate biopsies taken before and after the lifestyle changes.

After the three months, the men had changes in activity in about 500 genes — including 48 that were turned on and 453 genes that were turned off.

More on the human ‘super-organism’

Intestine and gut microbeThere’s a good short piece, Humans Have Ten Times More Bacteria Than Human Cells: How Do Microbial Communities Affect Human Health?, in Science Daily, picks up on some of the themes we discussed in The human ’super-organism.’ The overwhelming majority of cells in human bodies belongs to microbes — the article says 10 bacteria cells for every human body cell (does it make you feel tired to think how much bacteria you’re carrying around?). Recognizing that we are a shambling micro-cosmos of oraganisms (or ‘microbiome’) suggests new understandings of all sorts of things, including disease. The Science Daily article points out that ‘changes in these microbial communities may be responsible for digestive disorders, skin diseases, gum disease and even obesity.’

There’s one passage in particular that I thought was worth posting, even if I don’t have too much to add:

“This could be the basis of a whole new way of looking at disease. In order to understand how changes in normal bacterial populations affect or are affected by disease we first have to establish what normal is or if normal even exists,” says Margaret McFall Ngai of the University of Wisconsin, Madison.

The microbiome research is particularly interesting to us at Neuroanthropology, even though it’s not strictly about the brain or nervous system, because it’s a particular compelling demonstration that the human body is a dynamic system; that is, the body is a system of different forces and processes, at a number of scales, that together continually produce the whole, sometimes in equilibrium and sometimes in ways that produce dysfunction.

It’s Our Fault: Denial, Disease and Addiction

By Danny Smith, Jimmy Wilson, Will Yeatman, Rachel Guerrera, and Mark Hinken

It’s our fault. But let’s spread the blame. The burden also lies on the shoulders of the educational community. And society itself. There is a serious misconception that exists. This misconception is that chemical dependence is not a disease. By not recognizing chemical dependence as a disease, society continues to hold harmful stereotypes about alcoholism and drug addiction.

The goal of this blog post is to address this major problem facing drug addicts and alcoholics. Society enables chemical dependence by causing denial. Denial helps create a vicious cycle that traps addicts. They tell themselves they do not have a problem and reject the idea to others that a problem exists.

However, denial is not just prevalent in cases of chemical reliance. It is common in everyday life, seen in issues concerning body image, gambling, sex and social interaction. In these cases, like addiction, denial stems from the social stigmas produced by society.

In today’s culture having a slim and fit body is heavily desired and expected. People who do not conform to the lofty standards set by models and Hollywood elite often feel abnormal and subject to ridicule. As a consequence anorexia, bulimia and dysmorphia have become more common among the current population. However, though these three eating disorders are labeled as real diseases, they are viewed as taboo in society. Therefore, people who suffer from anorexia often deny to others or even themselves that they really have a problem with a serious disease.

US society does not often pair diseases such as anorexia and alcoholism with diseases like cancer and Parkinson’s disease. Yet they are all chronic diseases. If the United States came to view chemical dependence with the same empathy as cancer, we could help eliminate the destructive low self-esteem and denial found in chemically reliant individuals.
