Plasticity Neural Network Based on Astrocytic effects at Critical Period, Synaptic Competition and Strength Rebalance by Current and Mnemonic Brain Plasticity and Synapse Formation
In addition to the weights of synaptic shared connections, PNN includes weights of synaptic effective ranges [14-25]. PNN considers synaptic strength balance in dynamic of phagocytosing of synapses and static of constant sum of synapses length [14], and includes the lead behavior of the school of fish. Synapse formation will inhibit dendrites generation to a certain extent in experiments and PNN simulations [15]. The memory persistence gradient of retrograde circuit similar to the Enforcing Resilience in a Spring Boot. The relatively good and inferior gradient information stored in memory engram cells in synapse formation of retrograde circuit like the folds in brain [16]. The controversy was claimed if human hippocampal neurogenesis persists throughout aging, may have a new and longer circuit in late iteration [17,18]. Closing the critical period will cause neurological disorder in experiments and PNN simulations [19]. Considering both negative and positive memories persistence help activate synapse length changes better than only considering positive memory [20]. Astrocytic phagocytosis will avoid the local accumulation of synapses by simulation, Lack of astrocytic phagocytosis causes excitatory synapses and functionally impaired synapses accumulate in experiments and lead to destruction of cognition, but local longer synapses and worse results in PNN simulations [21]. It gives relationship of intelligence and cortical thickness, individual differences [22]. The PNN considered the memory engram cells that strengthened Synapses [23]. The effects of PNN's memory structure and tPBM may be the same for powerful penetrability of signals [24].And PNN considers the non-classical quantum computer in brain plasticity[25]. Memory persistence inhibit local synaptic accumulation. It may introduce the relatively good and inferior solution in PSO. The simple PNN only has the synaptic phagocytosis.
