Modular Brain Theory

A Hard Science of Human Behavior

To get back to the Moon and stay, we will have to deal with people and we will have to deal with them the way they are, not some way we would like them to be. To achieve our goal we will not need to know every little thing about human beings, but the things we need to know, we need to know very well indeed.

The many technical people in our community would much prefer that our actions be based as much as humanly possible on hard science. The lousy-goosy foundations for most schools of management leave us with a very queasy feeling.

Oddly enough, the great strides made in recent decades in understanding the human brain are starting to offer the possibility of managing humans based on hard science.

Module in the Brain

The new understanding that offers this promise is Modular Brain Theory. In this theory the human brain is modeled as a large collection of small modules that evolved to do specific functions. Modern instruments, like Functional Magnetic Resonance Imaging (fMRI), now make it practical to identify many of these modules with specific brain tissue.

In January 2007, one of these modules was pinned down that makes a good example. This module generates addition to nicotine. Specifically it generates the withdrawal craving. A two-pack-a-day addict who has a stroke destroying this bit of brain tissue not bigger than a crumpled postage stamp will be instantly cured.

Other identified modules provide such functions as:

Identifying faces
Attaching emotions to faces

Creating the Eureka experience
Setting off an alarm if a series of sounds is unexpected
Preventing suicide

Of the hundreds of such modules in the human brain, perhaps 50 have been specifically identified. The total could easily exceed one thousand.

Common Properties

All the brain modules have a few common properties that help us to propose new candidates and then track them down.

They occur in all human beings
They provided some evolutionally valid function to our ancestors
They work automatically and cannot be turned off
They work very fast
They are always on when you are conscience
Your conscience mind can overrule them, but only after they have fired.
Knowledge of their existence does not effect their operation in any way

The Eureka Experience

When you solve a difficult problem you often get a great feeling of eurphoria and accomplishment, sometimes called the Eureka experience. The specific brain modules that generate this experience was identified at Northwestern University in 2004:

Neural Activity When People Solve Verbal Problems with Insight

The key Eureka fMRI scan is shown at the top of this article.

Technical people love this experience and it will be one of our main drivers in returning to the Moon.

The Mirror Neurons

Another good example of a pair of useful modules is the Mirror Neurons. If you are watching someone do something these modules run the mirror image of the actions you are watching in your brain. They are literally practicing the act right up to the point that you move your muscles.

This is clearly important for a species that is dependent on teaching its young most of what they need to survive. This module was first discovered in primates, where it was called Monkey-see-Monkey-do. Its mirror imaging function was later discovered in humans and gave it its present name. Only later was it found how important these modules are to learning.

Modular Buy-In

But what does this have to do with building a return to the Moon community?

We will need to generate buy-in in massive numbers of people to achieve our goal. The module responsible for buy-in, (see Buy-In Explained) has not yet been positively identified, but function has so many of the attributes of a brain module, like Eureka above, that it is likely to be driven by one. If we make that assumption then we can assume and use the following characteristics of buy-in:

All human beings exhibit buy-in
It operates automatically
Buy-in can be over ridden by higher brain functions
It has a link to the visual centers of the brain
It has a link to the language centers of the brain

Community Building

From these characteristics we can see that we must invite people to buy-into our back to the Moon idea, and we can tell them exactly what we are doing. We must also provide language input to this module while they use the visual center of the brain to envision success. Clearly buy-in had major evolutionary advantage in making group projects at the village level much more effective.

We can make use of this information. The time is right for the application of latest brain science to the solution of the great problems of human kind.
