MEMORY, CHEMISTRY, BRAIN, DNA
Memory, chemistry, brain, DNA
Today this Google alert has reached me. The basic idea of this article is about memory. Memory is one of absolutely crucial phenomena not only of brain but also of evolution. If there were no memory system that enables to pass gained information to the next generation, evolution would not function at all, as no organism would be able to make any gains from its ancestors, and it had to discover everything anew. This would be to costly, time and energy consuming, and it would lead to no evolution at all or only evolution in extremely slow pace.
If brain or DNA can remember some information gained by organism, then it can also pass this information onto the next generation and save energy of the next generation as it does not have to analyze all the new signals, far more it can build up, by adding additional information to already save information from its parents and pass double amount of information to the next generation, and thus speeding up evolution through faster adaptation.
In few of my previous articles to this topic I wrote that one can reduce evolution to only two subjects: physics and statistics. Physics constitutes all bases for material preservation of information and statistics must be understood in the sense of repetition. If something is repeated many times it will be remembered. I have already suggested in my works that brain memory as well as memory of DNA must be multi-level memory (MLM). Organism must have the opportunity to decide whether some information, some signal from its informational environment is important, or not, and how much important it is. Therefore such memory system must be a multi-level memory system.
Our brain functions accordingly, if something is repeated many times it will be better remembered, if something is repeated only few times and then comes a long time with no repetition s of this signal whatsoever, then, brain or organism decide that this particular information is not important anymore and is sent to lower memory levels and at the end it can be completely deleted from memory.
If some signal is repeated many times and the number of repetition reaches certain number, then such information will never be deleted, it can only decrease in its importance and will be stored at the lowest memory level, but never erased.
Now, the today Google alert leads to scientific laboratory experiments that seem to bring extremely strong evidence that my understanding of evolution, and the role of the ability to store information, that means some memory system.
