A derived mechanism of the nervous system functions explains aging-related neurodegeneration as a gradual loss of an evolutionary adaptation.

CONCLUSION: The derived testable IPL mechanism that can explain nervous system functions is capable to have evolved. An adaptation to prevent IPL hemifusion from progressing to fusion is likely the last stage of evolution. Since the IPL mechanism is utilized during every event of learning, any aging-related factors that can weaken this adaptation can cause IPL fusion and lead to neurodegeneration.
