Functional aspects of memory and forgetting

On the basis of the synaptic connections dynamics between the neurons the processes of occurrence of memory, forgetting and appearances of the new information in a human brain are considered. It is marked, that the huge quantity of the synaptic connections inevitably results to them instability. Forgetting information in norm it is defined by the break of synaptic connections, and memory information it is connected to restoration of these connections. In norm there is a speed balance of these processes. However, if the torn synapse is reconnected to the spine of another neuron, the new information may appear in a brain. As consequence the forgetting the previous information is possible. It is essence of creative process. A savant syndrome and autism are connected to excessive durability of the synaptic connections that results in absence of creative abilities. The impossibility of described dynamics of a brain work technical modelling, i.e. creation of a full-fledged artificial intellect is marked. Some genetic-molecular aspects of the synaptic connections restoration are considered.
