In the introduction to this chapter, we discussed the role of famine during early prenatal development and how, through epigenetic effects, it influenced the health of individuals as adults. One effect that has been observed in people who were conceived during the Dutch Hunger Winter is that they suffer more cognitive decline later in life. If these individuals were autopsied after death, what differences might you expect to see in the chromatin of their brain cells? What do the mouse studies of cognition and epigenetic effects suggest?

Learning and memory

Learning is defined as a relatively permanent and irreversible adaptive change in behavior. It always results from experience. The ability of an organism to store and recall the effects, sensations, and knowledge gained through learning and experience is called memory.
