Are neurons enough?

Mystery of Neuron Legos

We know that neuron is a limited human memory which is created for a finite number when you are born but not to be gained but either to be surviving or losing. This surviving is generally meant as using the nuerons, and there are a lot of discussion about information processings, "parallel" and "sequesntial", approached from this surviving point. As a matter of fact, for instance, it is believed that there exists the parallel processing in visual information, and all information coming from eyes are processed at the same time, and that there exists the sequential processing in logical thoughts, and only one thought may be processed at a time because there are not enough neurons in our brain for each one to hold a complete thought. However, now, if I approach "parallel processing" and "sequential processing" matters from the point of losing neurons, I notice that it derives the basic neuron_connection structure and implies the importance of synapses freedom in movement. As the first of all the deriving processs, let's think of an example of "paralell processing". Suppose that I saw a creamy color building with a little stairs and 3 doors, and just passed by this building. Then I don't remember what the color it was, how many doors there are, or even wether the builing exists after some minutes. So, this phenomena can be described as a temporally lighting_up (activated) in each neuron in the brain. That means that the each neuron could have own single word such as creamy, color, stair, door, and building, and in the moment of seeing the building, visual information activates all axons of each neuron. Therefore, the states for each neuron could be connecting color_neuron to creamy_neuron with sysnapses transmitting between the neurons (this situation still happens as parallel lightening_up), and building_neuron, stair_neuron and door_neuron might be individually activated. If I draw this in picture, it would be folloing. (* = nurons, \ = axon, ` = synapses, and ! = light_up for all the following picture): !color * !building * !stair * !door * \ \ \ \ ` !creamy * \ However, what if sequential processing of thinking of my own bicycle, has the same neurons holding each own word from the following thought? "My bicycle is creamy color, costs $50, and has a scratch" ----------------(1) Since there are a color_neuron_cell (here I call color_neuron as the same as color_cell and apply this for rest of the names) and creamy_cell, activated before in paralell example in my brain, I must light-up my these same cells to activate in the same location. But this sentence should be still a one thought, and the color_cell, creamy_cell, , $50_cell, and scratch_cell must be connecting to each other sequentially while creamy_cell and color_cell was connected and activated themselves individually in the previous situation. Therefore, this is said that "paralell processing" is activated as a part of "sequential processing". The picture could be the following. !color * building * stair * door * \ \ \ \ ` / !creamy * * scratch ! \ ` ` / * $50 ! Now, consider a case that neuron is not surviving but losing. That is, from my experience, to give yourself a situation, ostracized from outside environment and withdrow your activities. When I was in junior high school in Japan, I was a class president and have been ostracized. I have been helping a classmate, who was ostracized by all other classmates, because the classroom teachers asked me to do. My possition in relationship was neutral among the ostracized girl, all other classmates, and teachers first, however, it turned me into a subject of isolation from and against all classmates including the ostracized girl I helped, with some little misunderstandings what I have done. Then, I have started not to notice or have attentions in anything, anyone in the school because I just wanted protected myself from hurting by misunderstandings "I am a bad girl" others believe. Though this incidence was resolved in a couple of month, but I have experienced psychosomatic illness in mentally and physically. I have still been experiencing my abilities has been weakened and have difficulties to get it back as it was in study such as speedy math calculations which used to be something I was good at. From this idea, I can say that at least my neuron had not been activated during this inactive situation but it is ture that I can't prove wether my neuron has been decreased or deminished for some. But are my neurons after the incidence compensating to do things as I used to do? With this background, let's consider the sentence (1) above. After 20 years, I might not remember what the bicycle's cost was, and the scratch. But this is still true that I could suddenly remember what they were. So, these could be pictured that the $50_cell and scratch_cell were left alone or the connection between those cells are weakened as forgotten state and latter as suddenly_remembered state. Forgotten State Suddenly_Remembered State color * color * \ \ ` / ` / creamy * * scratch creamy * * scratch ! \ \ ? / ? / * $50 * $50 In another word, the stimulus, synapses between the cells, could have been decreased, away, or dessapeared. But when you suddenly remembered, this synapses could be or should be involved to connect to the other cell. Also, if during this forgotten state above, this scratch_cell might connect with another cell, for example, when I buy a car and saw a same scratch without having any chance to notice that the scratch is the same as the bicycle. Then, the derived idea from two examples of processing, "parallel model of neurons process is a subgraph or a path of sequential model" can be more derived to the each neuron's ability to construct a new model by reconnection since each neurons could be disconnected and reconnected again. That means that the graph of paralell and sequential neurons should be constsist of each individual neurons which is actually regulated by the synapses. Thus, this can be concluded that this mystery of synapses movement of freedom could be a interesting regulation while each neuron is trying to survive by holding other neurons with it, and the synapses might be the real controler of human's memory or information from the outside environment to come up from brain including the paralell and sequential process reconstruction.
