A groundbreaking brain-scanning study has revealed that babies as young as one year old can form memories. The research published today in Science challenges the long-held theory of infantile amnesia, which suggests that infants cannot remember their early years due to difficulties recalling memories.
According to co-author Tristan Yates, a neuroscientist at Columbia University, the findings indicate that memories from infancy might still be present in adulthood, but are inaccessible.
