We propose that high neurogenesis levels negatively regulate the ability to form enduring memories, most likely by replacing synaptic connections in preexisting hippocampal memory circuits. Interestingly, the decline of postnatal neurogenesis levels corresponds to the emergence of the ability to form stable long-term memory. Infants (humans, nonhuman primates, and rodents) exhibit high levels of hippocampal neurogenesis and an inability to form lasting memories. Here, we propose a hypothesis of infantile amnesia that focuses on one specific aspect of postnatal brain development-the continued addition of new neurons to the hippocampus. Biological explanations of infantile amnesia suggest that protracted postnatal development of key brain regions important for memory interferes with stable long-term memory storage, yet they do not clearly specify which particular aspects of brain maturation are causally related to infantile amnesia. Psychological/cognitive theories assert that the ability to maintain detailed, declarative-like memories in the long term correlates with the development of language, theory of mind, and/or sense of "self." However, the finding that experimental animals also show infantile amnesia suggests that this phenomenon cannot be explained fully in purely human terms. How can these findings be reconciled? The mechanisms underlying this form of amnesia are the subject of much debate. Although universally observed, infantile amnesia is a paradox adults have surprisingly few memories of early childhood despite the seemingly exuberant learning capacity of young children. Recognizing that international associations are generally confronting world problems and developing action strategies based on particular values, the initial content was based on the descriptions, aims, titles and profiles of international associations.In the late 19th Century, Sigmund Freud described the phenomenon in which people are unable to recall events from early childhood as infantile amnesia. UIA’s decades of collected data on the enormous variety of association life provided a broad initial perspective on the myriad problems of humanity. This suggests that amnesia for early events. The initial content for the Encyclopedia was seeded from UIA’s Yearbook of International Organizations. Among 7-year-old children, 60 percent recalled the same events while children tested at age 8 or 9 remembered only 36 to 38 percent of the events. By concentrating on these links and relationships, the Encyclopedia is uniquely positioned to bring focus to the complex and expansive sphere of global issues and their interconnected nature. Historically, adults were the only participants in research on childhood amnesia. These connections are based on a range of relationships such as broader and narrower scope, aggravation, relatedness and more. It is currently published as a searchable online platform with profiles of world problems, action strategies, and human values that are interlinked in novel and innovative ways. The phenomenon, referred as to infantile or childhood amnesia, is in fact the inability of adults to retrieve episodic memories that took place during the first two. The Encyclopedia of World Problems and Human Potential is a unique, experimental research work of the Union of International Associations. The research, conducted by scientists at NYUs Center for Neural Science, reveals the significance of learning experiences over the first two to four years of human life.
