I don't know if there are many people like me who have been thinking about who they really are since a long time ago, especially when I was a child. Whenever the waiting to fall asleep at night when the brain began to crazy to think, always so curious about their feeling is unspeakable and exists in the brain, thinking with emotion and so on, at that time I thought this is shouldn't exist problems, and began to constantly tell myself to try to live in the moment of life, and stop to think about a similar problem.
It was not until some time ago that I decided to think about this question again, and tried to express my consciousness visually based on my own hypothesis, so as to give myself the space to think further and answer this question in this stage.
There's a concept here, and what we're going to explore next is the exploration of the non-reified sense of self in human beings and even in biology; In other words, what is really at the heart of your own actions and thoughts. Therefore, in this step, we have to put aside the constraints on physical thinking. Consciousness exists in the brain, so the brain is itself in the sense of entity. Our body and organ systems all serve the brain to complete the instructions given by the brain. So it is tempting to wonder if the failure of limbs and organs does not directly lead to the death of the organism itself if the brain remains active and healthy. Does that mean that all the accessories except their own core are replaceable or repairable? There is no denying, of course, that one's own body is still the gift of life and unique and part of oneself.
The relationship between the brain and the body is consistent with the objective reality that any external stimuli and behavioural instructions in the brain are transmitted by electrical signals through a number of neurons. In this case, the neuron is actually playing a role with the concept of the channel, so it can be understood that the electrical signal has already completed the judgment and command of self-consciousness in the transmission process of the neuron channel. So we are influenced by what is or what determines our self-consciousness in the process, a bold guess these channels is the consciousness of our ontology, through all the outside information channel can become neurons possess self-awareness judgment behaviour, also can say this is our real non-figurative ontology, and what is the content in the channel is what we want to continue to explore the next dimension.
First, we visualise self-awareness as a channel that acts as a conduit for the electrical signals of neurons. So if the channel is the ontology of the individual consciousness, then what is the difference between the creatures? It depends on another component of the channel, which is the memento, the residue of memories that we create through our experiences. The channel of consciousness ontology becomes the storage point of memory fragments. When the external information is input, we will judge according to the memory fragments accumulated at the moment, thus generating subjective consciousness and giving behavioural instructions to the external information. Meanwhile, the memory fragments will be supplemented and replaced at the same time of constant input of external information, finally forming a gradually mature subject consciousness in the process of constant increase and replacement. We use an example to illustrate this process of replacement. For example, if we generate subversive new information input for the same thing or a definition, we will have the behaviour of supplementing or replacing this part of memory points. It can also be simply understood as refreshing the three views on a thing. However, we do not have too many ways to give subjective consciousness judgment to brand-new things, so what appears is indifference, ignorance, and curiosity. At this time, we generate new memory points and carry out residual storage in the process of information passing through the channel of consciousness. But when the same event is stimulated twice, we can make some behavioural responses and judgments based on the stored memory fragments. So to some extent, all the conscious decisions and judgments we give are based on all the fragments of memory that are leftover from our past experiences. In other words, the differences and characteristics of living things may depend on the subjective judgments brought about by the different experiences of living things. From the materialist point of view and from the substantive dimension, our essence, which is ourselves, is the combination of this neuronal channel and the fragments of memory.
The whole process of self-awareness is mainly divided into three parts:
(1) (The process of subjective judgment)
External information is input into the neuron channel as an electrical signal, and under the action of accumulated memory fragments, self-judgment and behavioral instructions are generated, which serve as the fixed output of the conscious process.
(2) (The formation of new memory points)
When new things are input as external information, electrical signals cannot generate self-consciousness expression through the accumulation of memory fragments. In this process, the current experience will be stored in the neural channels as the deposit of new memory fragments.
(3) (Old memory point renewal process)
In the constant electrical input of the same thing, the constant fragmentation of memory makes the self-conscious output continuously faster and more skilled. However, when different or subversive electrical signals of the same thing are input, there will be a process of supplementing or replacing the memory points of the same thing after the memory fragments are output.
