no so much on memories but the ability to link the feelings or emotions felt from an action to a similar mental state experienced before that stimulated the same area in the brain.

take for example the amygdala of the brain is both activatable through eating chocolate or having sex. therefore the ventral tegmentun area in your head tells you that it oozes the same feeling. so by default, sex = chocolate. but due to physical stimuli we experience, it isnt.
