Cracking the Code: Autism's Link to Childhood Memories

Researchers have discovered a link between maternal immune activation during pregnancy and the preservation of memories formed in infancy, challenging the understanding of infantile amnesia. In a mouse model, inflammation induced during pregnancy altered brain development, preventing the usual loss of early-life memories. The study suggests that infantile amnesia may result from a retrieval deficiency rather than memory loss, as memories are stored but not normally retrievable. This research provides new insights into cognitive development, memory flexibility, and the potential implications for autism.
