| Abstract(in English) | In the development of the brain, it is known the phenomenon that synapses are pruned following over-growth. The pruning following over-growth seems to be the universal phenomenon in almost all area such as visual cortex, motor area, association area and so on. Chechik et al pointed out that synapse efficiency increases by systematic deletion. Since they did not provide theoretical treatment of this phenomenon, we will analytically discuss synapse efficiency to evaluate the effect of the pruning following over-growth regarding as the auto-correlation type associative memory. In the limit that connecting rate c is extremely small, we found that synapse efficiency in the case of systematic deletion becomes 2 |log C| times large as that of random deletion. |
