The ability to form enduring memories, most likely by replacing synaptic connections in preexisting hippocampal memory circuits.

We propose that high neurogenesis levels negatively regulate To the emergence of the ability to form stable long-term memory. Interestingly, the decline of postnatal neurogenesis levels corresponds Neurogenesis and an inability to form lasting memories. Infants (humans, nonhuman primates, and rodents) exhibit high levels of hippocampal We propose a hypothesis of infantile amnesia that focuses on one specific aspect of postnatal brain development-the continuedĪddition of new neurons to the hippocampus. Yet they do not clearly specify which particular aspects of brain maturation are causally related to infantile amnesia. That protracted postnatal development of key brain regions important for memory interferes with stable long-term memory storage, Biological explanations of infantile amnesia suggest That this phenomenon cannot be explained fully in purely human terms. Theory of mind, and/or sense of “self.” However, the finding that experimental animals also show infantile amnesia suggests The ability to maintain detailed, declarative-like memories in the long term correlates with the development of language, Psychological/cognitive theories assert that The mechanisms underlying this form of amnesia are the subject of much debate. Of early childhood despite the seemingly exuberant learning capacity of young children. Although universally observed, infantile amnesia is a paradox adults have surprisingly few memories In the late 19th Century, Sigmund Freud described the phenomenon in which people are unable to recall events from early childhoodĪs infantile amnesia.
