Episode 6: Smell and Memory

Smell is a powerful sense. In fact, psychologists and neuroscientists believe it is the most powerful of all the senses to evoke emotion and memory. This is because the olfactory bulb, which starts inside the nose and continues along the lower part of the brain, touches two areas important for processing emotion and memory: the amygdala and hippocampus. The other senses do not run the same course, so they do not have the same impact on memory and emotion. A smell is more easily linked to an event and the associated feelings of that event.
