Why do some troubling memories continue to haunt while others can be repressed?

Embryonic stem cells (marked in green fluorescent protein) that should become sex cells, in which the gene encoding Utx is not present. Each column shows a gene needed for sex cell development (top row – marked in red, purple and orange). After 12 days (bottom row) the expression of the four genes has stopped and, rather than develop into sperm or ova, the stem cells die
