Dr. Gen Matsumoto
Group Director, Brainway Group

Originally a physics researcher, Group Director Dr. Gen Matsumoto has adopted a physical approach to brain science. However, according to him traditional rules of physics often cannot be applied to real life. We spent a few moments with him discussing scientific thought, society and the future of research.
Int: The 21st century has been dubbed "the age of the brain". What does this mean for research?
GM: The 20th century was called the "age of physics," but what physics in that age dealt with was a "closed system" where things moved toward disorder. The objects of research that physics dealt with at that time were "lifeless things." It was this closed system that provided the grounds for the development of relativity and quantum theories.
Life, however, is an open system in which things move in an orderly form. The eyes, nose and mouth take shape where they are supposed to be positioned. This process is a mystery beyond the reach of traditional science. Traditional science can deal with the decaying process after the end of life, but has great difficulty explaining the processes within an open system.
Int: Could you elaborate on the this open system?
An open system is a system that borders simultaneously on two different types of environments. LetŐs take the planet earth, for instance. Our planet is placed in between two different environments - the sun and outer space. The earth manages to live in the flow of heat energy that comes from the sun and then passes it on to outer space. There is a similar flow for human beings as well. We sustain life on food intake and pass it on in the form of excretion.
Int: So to sustain life, then, it is just a matter of taking in materials and energy?
Not really. There is a third element: information. As an open system organ, the brain receives a variety of signals from the sensory organs. Brains could not sustain life unless these signals were processed into output in the form of information or, in other words, actions. If brains failed to develop their own information-processing systems that continually adjusted to the environment, they would remain unconfigured and less able to assist us in sustaining life.
Suppose a cup of tea is placed in front of you, for example. At first, the solution and its color may not make any sense. However, when you take a sip of water before seeing the tea, the action helps to form an essential concept that can be applied throughout life. The signals received by your brain become meaningful when they are processed into output or information.
Int: How does this configuring of the brain actually take place?
The configuring that takes place in our brains is identical to programming a mechanism to process information. In order to sort out the effective signals a decision about a definite target must be made. Ensuing actions then help to confirm whether the selected signals are really effective in attaining the objective. Without a definite purpose, active brainwork cannot really take place.
A simple example of this is getting up in the morning. Some people complain of trouble waking up early in the morning. This is not really surprising if you consider that they may have no motivation such as, "I want to do this or that first thing in the morning."
I think that one of the reasons it may be difficult in present society to generate daily purposes before waking is the emergence of a particular social environment that emphasizes "quantitative achievement," which is undoubtedly detrimental to the growth of healthy brains. The fundamental functioning of the brain system is to identify objectives and bring forth output in order to attain objectives. The growth of our brains depends on how they can develop such objectives by themselves.
Int: How does this negative social environment actually play out in our lives?
Unfortunately, we have been raised since childhood to adapt our brains forcefully to parental and social rules. Brains are imprinted with notions, such as obedience to parents and society, from a very young age in order to ensure our survival. The result is a strong sense of dependence on other people. Dependent brains are unable to fix their own objectives. Brains have no other choice than pursuing the prevailing social norm. People tend to believe that they can decide their own objectives based on their own will, but all they are doing is creating effective systems to attain objectives that have in a sense already been laid out for them. If they fail in such attempts, their dependent psychology comes into play and they start putting blame on other people or circumstances.
Int: But failure is a natural occurrence in the progress towards an objective, so isnŐt it at some level a good thing?

It can be if people can decide on their own objectives and approaches to a target. For these people failure can be viewed as a good opportunity to reflect on the method of their approach. Failure becomes failure only when they admit the failure.
Today's society, however, lays a greater emphasis on achievement appraisal. In terms of the brain system, achievement is synonymous with information output. The aim of our brains should be to create internal processes that challenge the development of the program in order to assess the output. The output is no more than a process.
I think today's society makes a fundamental mistake in giving good marks for methods rather than objectives. In any society where challenge is suppressed, the healthy development of brains is going to be an issue.
Int: In the world of research, researchers continually challenge themselves and the norms of their fields. Does this equal "healthy development" of science?
Under the present assessment system, results are important factors in research appraisals. Any research that produces quick results can be conducted through a smart combination of known facts. Such research, though, may not be research in the true sense of the word.
Suppose a researcher picks his own research target but fails in his initial approach, for example. He tries all the other possible means according to his knowledge without success. Faced with such a seemingly insurmountable problem, he questions what is wrong with his target and approach. His distress is a signal that he is really at the beginning of genuine research.
Natural science must be a science such that any encounters with unexplainable phenomena result in a change in traditional scientific perceptions and the creation of a new philosophy. We cannot create a new science if such phenomena can be explained by a mere change in the approach method while sticking to the traditional philosophy.
Int: Which then brings us back to "the age of the brain".
Yes, with regards to life science, we may very well be in an age marked by the end of one science and the beginning of another.
