Research on brain or mind: How done?
I attended a session of TEDx talk in Awkar (Lebanon). The meeting started around 10 pm and ended at 1:30 am. And we watched several TED talks on brain research and language. The discussion and the friendly association inspired this article.
Since the Italian Galvani’s experiments on reactions of frog to electrical impulses in the 18th century, study on brain functions basically relied on binary (on/off) activities of neurons and nerves.
Currently, experiments are done using non-intrusive tools and techniques such as photo-voltaic (light) energy impulses. The pores of particular axons in network of neurons and synapses in insects are activated by the light; the insect is thus programmed to behave as lights go on/off.
Research is focusing on selecting specialized network of neurons that can be activated and programmed so that particular functions of the brain are localized and controlled. This strategy says: “let us investigate sets of neuron networks with definite functions. As more networks are identified then, extrapolating procedures might shed better lights on how the brain function”.
It seems that this strategy in research is adopted frequently among teams of neuro-scientists.
Basically, although the brain does not function as current computers do (advanced computers are being tested, working on living organisms such as bacteria that are programmed with artificial intelligence rules), the brain and nervous systems are activated in binary modes as computer by surges of energy impulses. Hormones (chemical compounds) in body activate and deactivate neurons for particular functions in the brain and the body.
I like to suggest a complementary strategy for neuron research based on investigating pairs of hormones as a guiding program.
The idea is to mapping particular pairs of hormones, among the hundred of them, that are specialized in firing and cancelling out stimulus for activating certain tasks.
The next step is to construct a taxonomy for all the tasks and functions of the body and then regrouping the tasks that share the same network of neurons activated by particular pairs of hormones.
The set of tasks for a pair of hormones do not necessarily engage a direct function: they may be accessory and complementary to a function such as controlling, maintaining, decision, motor, feedback critics, actors, learning…
The variety of hormones correspond to different external senses, internal senses, and special nervous structures and molecular cells in the body and the brain. The number of hormones is countable, but combinations of pairs of (on/off) hormones are vast. I suppose that a hormone might be playing a valid role in several tasks while its opposite hormones might be different for other sets of tasks.
I have this strong impression that research on animals and insects are not solely based on moral grounds or ethical standards. The practical premises are that animals are far more “rational” in their “well-behaved” habits than mankind. And thus, experiments on mostly male insects (even female insects have more complex behaviors and body instability) are more adequate to logical designs.
The variability (in types and number) in experimenting with particular animal species are vastly less systematic than experimenting with mankind: For one thing, we are unable to communicate effectively with animal species and we have excuses to hide under the carpet our design shortcomings.
I think there is a high positive correlation between longevity in the animal kingdom and level of “intelligence”.
Species that live long must have a flexible nervous systems that rejuvenate, instead of the mostly early hard-wired nervous systems in short-lived species.
Consequently, the brains of long-lived species are constantly “shaking”, meaning cogitating and thinking when faced with new conditions and environments.
Mankind observed the short-lived species (with mostly hard-wired nervous systems) and applied control mechanisms on societies based on those “well-behaving” animals for control and organization models of communities of mankind.
It is of no surprise that control mechanisms on human societies failed so far in the long-term: Man is endowed with a brain shaking constantly and rejuvenating most of his nervous cells and submit but momentarily to control mechanism, long enough to subdue a community for many years.

You can now live very long: what are your plans for old age? (February 14, 2009)
With the current progress in the medical field you can prolong your life 150 years. If you ca afford it then there are no major barriers to live very old and functional too with a basic sane body. The gene for longevity was discovered in 1998; the cell was extracted from a bacterium that can withstand massive doses of irradiation, heat, cold and then can reconstruct its ADN.
After fifty the outer membrane of your eye is no longer supple; then you can replace it; it is a very common operation. At the age of 110 the aorta has to be replaced; it is done frequently. At the age of 150 your skin is totally useless; then collagen is injected; actually you don’t have to wait that long; the injections are performed in young bodies. Like an old car, new organs (or spare parts) are transplanted; it is done already with countless organs and even produced in laboratory from cell stumps.
There are on the market many hormones targeted for longevity such as growth hormone EPO, melatonin, Viagra, and the hormone DHEA for longevity; all of these hormones are secreted by the glands but they can be artificially produced to supplement the aging body.
I would be curious to know the variety of alternatives for padding your spare time when you grow old, functional and relatively sane, bodily and mentally. Send me your plans; let them be imaginative. Your plans don’t have to be so damned practical to correspond to our current conditions of aging since the remedies are already available.
I wish in my old age to have a team of helpers visit me once a week, all the team on the same day so that I might reserve the week for my activities and reflections in solitude. This team should bring all the essential provision for a week, just enough to survive because I need to feel short on provision by the end of the week and keep struggling with the survival process; that is a sure way of keeping alive and balanced. This team will maintain and repair the house and do paperwork or administrative tasks. I guess all elder people are not to be bothered with driving and hitting the various administrations; they have done their share of stupid slave work.
In my old age, all that I want to do during the week is be able to see; read, write, and publish; I don’t mind having good hearing: that would be a blessed bonus. I would also follow the news and see movies on cables. It would be nice to have my relatives, nieces, and nephews to visit me occasionally when they need a listening ear: it is always great to recollect the troubles of youth and their struggle for life. I would like to be invited for a swim or to a skiing resorts so that I can refresh my visuals of the newer activities of youth.
