Infant rats and mice form more new neurons (a process known as neurogenesis) in the hippocampus than guinea pigs do, which is believed to contribute to the rapid forgetting of early memories. This high rate of neurogenesis in the developing brain of rats and mice disrupts the stability of newly formed memories, making them more prone to being forgotten.
