Cellular memory (CM) is a parallel hypothesis to BM positing that memories can be stored outside the brain in all cells. The idea that non-brain tissues can have memories is believed by some who have received organ transplants, though this is considered impossible.
Cellular memory is an alternative theory to brain memory, suggesting that memories are not exclusive to the brain but can be stored in other cells throughout the body. This idea is also related to the notion of "past-life memories" held by some individuals who have received organ transplants.
