Organic memories

Ferrocene copolymers, (II) and (III), exhibiting redox potentials were prepared by Choi et al. (2) and used in organic memory devices. 

For some compounds, no difference in toxicity has been observed between time-varying or repeated and continuous exposures. This situation can occur when responses are related to peak exposure rather than time-weighted exposures, when exposures are cumulative (compounds with slow depuration rates), or when effects are only slowly reversible (organism memory van der Hoeven and Gerritsen 1997). 

Principle 9 We have at least two ways of organizing memory—spatial memory and rote learning. When information is merely memorized, without being rooted in experience, the information is soon forgotten. CTL encourages students to seek connections between information and experience. 

The Memory Reconstruction Method, in conclusion, gives us two general principles that must be valid for all systems which increase their own complexity, and embryos are such systems. The MRM model predicts therefore the existence of biological structures which are equivalent to reconstruction codes and to memory matrices. More precisely, the model leads to the conclusion that in embryos there must be codes and memories which are made of organic molecules, i.e. organic codes and organic memories. At this point, therefore, we can go back to biology and look for the existence of such structures in real life. 

Neural embryonic development, in conclusion, appears to be understandable only if we admit that its mechanism is based on organic codes and organic memories. Without these structures, an explanation becomes virtually impossible, and one can only hope that future research will be able to prove conclusively the reality of their existence. 

Determination and body plan are both arrangements of structures in space which are conserved in time, and therefore behave as organic memories . They are veritable stores of information, but in this case it is three-dimensional information that they are carrying. The problem is that the concept of three-dimensional - or contextual - information is difficult to deal with, and often it is confused with the idea of three-dimensional structure tout court. This is why it is... 

Perhaps biologists will have to consult artificial-life engineers, and will be told that the existence of organic codes goes hand in hand with the existence of organic memories. And this will give them other problems to think about Do organic memories exist Where are they How many are there In order to answer these questions, there will have to be a third phase of development, and attention will return once more to experiments. 

The book goes on to explain how organic codes and organic memories can be used to shed new light on the problems biologists encounter in cell signalling, epigenesis and embryonic development. A mathematical model is presented to show how embryos can increase their own complexity by the use of a code and a memory. 

The third model is an application of similar considerations to mental development, especially with respect to language. One kind of organic memory accounts for the acquisition of the capacities that appear early in the ontogeny of language, then a second takes over. Again, codes are absolutely indispensable, and the emergence of new ones has been a key innovation in the history of both life and mind.
