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.
The concept of cellular memory suggests that memories may not be limited to the brain, but can be stored in other parts of the body. However, this idea is also linked to the phenomenon of people claiming to retain memories of their past life after undergoing an organ transplant, a notion that remains highly speculative.
