8. Human Brain

There are few basic limitations we have in the exploration of human brain. First, we do not have meaningful access to human brains while it is in operation. We cannot layout the brain on a table, and use all different kinds of instruments to examine it thoroughly at all different test points. Without such an ability to test, we cannot really know anything about human brain. The human brain is filled with nerve cells, called Neurons [Discovery]; more than hundred billions of them are there. In addition to neurons, the brain has almost ten times glial [Byron] [Kast] [Noback] cells. So the brain is far more complex than anything physical we can imagine in this universe. It is the best example of the complexity law. Thus all tests on brain will violate the simultaneity law.

Second, all the tools used in brain research are based only on electrical, electronic, or electromagnetic phenomenon of nature. We do not have tools that are chemical or biological in nature. The biological and chemical signals must be converted completely to electrical signals to derive information. We will never know how well we are converting all the features of these signals to electrical signals. Third, we are looking for the meaning of the memory data in this paper, and not just flow of electrical signals or dynamic activities of the brain, or the chemical composition of brain cells.

Fourth, the humans as subjects of experiments are inconsistent with the man-made technologies and associated test plans. A person may not try to remember things, may not want to remember things, and may not be interested in seeing the details [Desimone] based on their philosophies and life time experiences with the GST. Thus all researches on human subjects may fail to show how the memory is generated and where it is located.

Mental imagery activates parietal areas, particularly intra-parietal sulcus [Just]. It is believed also that brain operations are governed by both local activities and distributed networked activities [Edwards]. These researches do not claim that the memory resides in that active region of brain, they only claim brain activities.

Some researches show that brain has short and long term memory storage space. But they have not identified any places inside the brain where these memory items are stored. Thus this storage categorization is functional and not brain hardware or structure related. This research cannot exclude the possibility that the memory is outside the brain. The research [Brady] shows that the storage capacity of long term memory is huge, which is consistent with the idea that the memory is outside the brain, therefore has infinite capacity. This will not deny the concept that our brain is only an input output processor like normal digital computers [Comer, pp. 207-213].

The paper [Motah] summarizes the confusions in research reports on the results of locations, localized vs distributed memory inside the brain. It has also been known that every human brain is physically and structurally unique for every person, that is, no two brains are same [Kirchhoff].  The author in [Rock] says that the human brain is a social organ; its physiological and neurological reactions are directly and profoundly shaped by social interactions which confirm our definition of memory and the GST concept of memory.

We see high correlation [Haier] between the size of brain volume of interests (VOI) and IQ, apparently indicating that intelligence is inside the brain. However this is related to only the electrical activity of the brain VOI. This experiment is inconclusive due to the fact that the brain activity is not local as VOI, the spontaneous activity at rest [Song] is an important contributor. Just to be clear, the brain memory scan images, like fMRI, only shows [Strauss] how activities move inside the brain, bottom up, networked, constructive etc. It does not show any meaning of the memory data. It also does not indicate that the memory is stored in the brain.

The paper [Hamani] reports an experiment where several electrodes were implanted bilaterally in the ventral hypothalamus. Once an electrode is stimulated the patient reported a perception of being in a park with friends. Standard perception of this experiment is that the image is stored in that specific location of the brain. However, it does not contradict the idea that brain is only accessing the image from the GST using our body sensors. Moreover, the reports also show that these experiments are not consistent and repeatable for other human subjects.

It appears that in cognitive science and in medical disciplines the word memory is used in a different context than the way we are using in this paper. The brain cells are considered as memory devices, but we have shown that they are physical objects and cannot store any abstract concepts. We have also considered the fact that memory is never generated by one person; therefore memory cannot reside inside our brain. In addition, we considered that every memory item has a meaning, which is defined using the simultaneity law. Without such a meaning, memory is meaningless.

9. Conclusions

Human memory has been defined as physical objects consisting of {data, action, purpose}. A purpose motivates us to perform some actions on some objects which generate the data. This data is the memory content and the purpose is its meaning. Without a purpose memory is meaningless. Every action we perform is linked, directly and indirectly, to the actions of many people of the world. We are not alone.  The collection of all these actions and the corresponding global purpose creates the global memory and gives its meaning. Thus global space time (GST) environment is the originator of our memory and has the complete meaning. This GST is outside our brain. Thus our brain cannot know the meaning and therefore it cannot also have the memory. Our experiences show that we get a better meaning only when we exchange information with others.
