UP TO YOU

(Vision Portal: Crocus, by Lowry Bell)

I've written before at this blog about human brain plasticity and at Maoist Orange Cake about Epigenetics and Cultural Re-Invention. I have more exciting discoveries to share with you.


Last month I watched a superb special on Nova at PBS called Ape Genius. It's introduced with "A rush of discoveries about chimps, from tool use to what they do for fun, are painting a surprising new portrait of ape minds." I've discovered it is also available online, divided into six chapters at the above link, and I've watched it all the way through again. I can't recommend it enough.

It acknowledges, rather tongue-in-cheek, our past human obsession with demarcating the DIFFERENCE between us and apes, our insecurity leaking through as apes crash one barrier after another and we move the goal-posts to keep us "winning". Even as this film does so, it makes it clear the distinction between ape intellect and our own will be the focus of this effort, but with (hopefully) more maturity:

'Congratulations: You are an ape. A "great ape," technically. Alongside us in this brainy family of animals are four other living species: chimpanzees, gorillas, orangutans, and bonobos (formerly called "pygmy chimpanzees").

'The biological gap between us and our great ape cousins is small. At last count, only 1.23 percent of our genes differ from those of chimpanzees. But mentally, the gap between us and them is a Grand Canyon.

'On an average day in the life of the human species, we file thousands of patents, post tens of thousands of Internet videos, and think countless thoughts that have never been thought before. On a good day, chimpanzees are lucky to exploit rudimentary tried-and-true techniques, such as using stone tools to crack nuts.

'Not only do we innovate more than the other great apes, we are vastly better at sharing ideas with one another. The majority of recent behavioral studies focus on information-transmission rather than invention. All of the great apes can learn new tricks by imitating a human or another ape. But only humans go one step further and routinely teach each other. Teaching may be the signature skill of our species, and researchers are now zeroing in on three particular mental talents that make it possible."

And here's where the documentary really grabs me: The three mental talents explored are "Mind-Reading", "The Triangle (as used in teaching)", and "Impulse Control". As they were described, I realized not only does this gap exist between us and apes, but within human culture, the development and value placed on these talents varies considerably, with enormous political and survival consequences. And, in my assessment, these extremely human, cooperative, advantageous traits are most under-emphasized in the conditioning we receive as white Westerners and in the conditioning we give males, particularly when cramming them into the "masculine" role.

Which begs the question: Why would we, as a species, be dampening down the most useful of our human evolutionary skills in order to pay obeisance to, say, impulsivity, mimicking without comprehension, competition over empathy and altruism, isolation and exploitation over interdependence?

I think we'll have to answer this question before we can reverse the trend. And, of course, part of the lesson will have to include that we have much more choice over our behavior and identities than not. We are not helpless in the grip of biology. We took another path, long ago, and it's quite possible, as a friend stated this week, we're witnessing yet another paradigm shift.

Watch it and tell me what you think.

In a related story, the New York Times just printed an article by Sandra Blakelee titled What a Rodent Can Do With a Rake in Its Paw. It begins:

"Degus are highly social, intelligent rodents native to the highlands of Chile. They adorn the openings of their burrows with piles of sticks and stones, have bubbly personalities and like to play games.

"But in a laboratory setting, degus can do much more than play hide-and-seek, according to a study in the online journal Plos One. They can learn to use tools."

The article includes a short video of a degu engaged in tool use. I could not find an independent link to this, so you'll have to go to the article link above to watch it. It goes on to say:

"While it has long been thought that tool use is a hallmark of higher intelligence, Dr. Iriki said, the brain structures that underlie such abilities may lie dormant in many animals with good hand-and-eye or paw-and-eye coordination. Training them to use tools in captivity provides insights into the plasticity of their brains, he said, and may shed light on how early humans evolved tool use in the first place.

"In the wild many animals use simple tools. Chimpanzees and crows actually create them. But an underlying question is, What changes take place in an animal brain when tool use evolves?

"To find out, Dr. Iriki initially conducted experiments with Japanese macaques, monkeys that do not tend to use tools in the wild. In the laboratory, he trained them to use a rake to reach out and retrieve their favorite treat, raisins. Later the animals learned to use a short rake to pull in a longer rake, which could then be used to fetch more distant raisins.

"As the monkeys developed these skills, their brains showed signs of gene activity in a brain region that integrates vision and touch. The same was likely to be true of the degu, Dr. Iriki said. The rodent has superb paw-and-eye coordination and a pad on its paw that can act like a thumb."

Once again, this study proves that what seems immutable -- genetic organization of a brain -- is actually quite plastic, and that genes themselves alter within an individual animal (not just through reproduction in new generations) as a response to environmental demand.

For those of us who have stepped beyond the Western rigidity of believing "God made us this way" and "Reality is concrete", we're not surprised to discover that we transform our own bodies by transforming our mind-set.

The "persistent delusion" (as I learned from Buddhism) that we all cling to was brought home to me in another way last week during a conversation with a friend. He pointed out that if you measure the wave length of blue light, it is clearly distinguishable from that of all other colored light. Ditto for yellow light, and ditto for green light. But if you shine both blue and yellow light on a surface, what we see is green. Yet if you measure the wave lengths, all that is objectively there is still just blue and yellow. The green is created within our brains: It's a perception, not a scientific property of the light.

I find liberation in this. Yes, it cuts me loose from the wharf, but there are others of us out here bobbing around in the current. All you have to do is love yourself as you are.

BROAD CAST: SOLSTICE 2007

Now we are in winter.

Tomorrow a group of us are gathering for the ritual practiced over millenia by our nature- and freedom-loving ancestors. We'll build a gigantic bonfire to remind ourselves that habeus corpus will return, and to hasten her arrival, we've constructed a giant elephant from faux wicker crap on sale at Garden Ridge which we will stuff with neocons and toss onto the blaze while singing "Hairy-legged lesbians sing / glory to our cunning ling!" You're welcome to join us. Bring your own jello salad.

(Postcard for Pine Street Art Works, copyright 2007 Liza Cowan.)

Speaking of Jell-o: Liza Cowan has at last begun her own blog, See Saw, concerning art and retail (as only Liza the Dyke Mother can do it). An auspicious sign of the year to come.


December 22nd is also Global Orgasm Day. Please contribute as best you are able. If you need help, reach out to live members of your community. Consensually, of course.

And I will award 50 (FIFTY) Sistahood points to anyone who can make the link between the graphic preceding this announcement (the cover of Marilyn Gayle's book) and why it is appropriate to the day in question.


Also, in the Old News For Some Of Us Department:

Jodie Foster acknowledges her female partner. After fifteen years.

Why is this news? I mean, here's a matching headline for you: Eva Longoria, Heterosexual!

Nobody with any depth of experience is buying that you were simply "protecting your privacy" -- not when you have two turkeybaster kids and managed to at least confirm their existence without rupturing your veil of mystery.

Nope, it's obvious that you were scared. And that you still are.

Good luck with that, honey. Next....


Returning to our obsession with all things polar exploration-esque: BBC News announces "Penguin sketches made by Captain Scott and Ernest Shackleton have been found in a basement at Cambridge University. The legendary explorers drew the pictures on blackboards, probably for public lectures, in 1904 and 1909." I, of course, immediately discerned character-revealing differences between the two sketches and have been moodily examining them for further illumination. Anyone else similarly afflicted?

In past posts here, I've written about waking up during surgery and other complications of anesthesia. There's a new movie out now, called Awake, which addresses the issue of "anesthesia awareness". The New York Times review states this "occurs when patients wake up during surgery because they are underanesthetized. In real life, these periods are generally brief. But the patient can indeed feel pain, ranging from minor to unendurable."

Ever since the late 1980s, with the advent of PET scans and other forms of advanced imaging studies, our ability to study the human brain has catapulted forward, and if it seems like new insights about consciousness and brain function arrive weekly, that's largely accurate. This week, the PBS series Wired Science aired a segment entitled Mixed Feelings: Helping The Blind See With Their Tongue. To quote from the website (which also has video and other links):

"Most of us see with our eyes, but what if we could see with other parts of our body, too? The idea may seem ridiculous, but it's already been done. Nearly a half-century ago, maverick neuroscientist Paul Bach-y-Rita discovered that it was possible to 'rewire' the adult brain, connecting regions in ways no one ever had imagined. Today, his ideas have given a handful of blind people the ability to see for the first time—using their tongues.

"For a long time, scientists believed that after childhood, the brain became 'fixed' in its ways and impossible to change. But Bach-y-Rita reasoned that because the nerves carrying messages from one part of the body to the brain are identical to those carrying messages from other body parts, it might actually be possible, even in adulthood, to substitute one sense for another."

I was especially intrigued by the work done with folks who have severe inner ear damage that renders them unable to tell whether they are prone or upright, leading to profound disability. "Rewiring" the sensory apparatus of the brain, using tactile regions instead of ear regions, has proven in some cases permanent, a complete cure.

The boundaries of human brain plasticity are definitely out of sight at the moment. For those of us who can manage balancing science, art, and faith simultaneously (however you define those) instead of believing them to be in conflict, the sense of hope and excitement is tremendous. It will, of course, mean giving up all the myths that race, class, gender, and sexual orientation are primarily "hard-wired" rather than manifestations of the brain's ability to adapt (even physically alter) to cultural demands placed on newborns. We'll have to accept that difference is mostly a matter of choice, and, as Stuart Smalley would say, "That's...okay."


In related news, this week's Proceedings of the National Academy of Sciences reports that human evolution is speeding up: "People are evolving more rapidly than in the distant past, with residents of various continents becoming increasingly different from one another, researchers say.

"'Rapid population growth has been coupled with vast changes in cultures and ecology, creating new opportunities for adaptation,'" the study says. 'The past 10,000 years have seen rapid skeletal and dental evolution in human populations, as well as the appearance of many new genetic responses to diet and disease.' And they found that different changes are occurring in Africans, Asians and Europeans."

Environment over biology. And -- feed your sisters and brothers elsewhere, because our vigor as a species depends on everyone's development.
