In experiments with mice, scientists taught animals to associate smells with certain pleasures: a banana smell with dessert and salt almonds. Later, an unpleasant irritating, a banana smell, because mice began to avoid a sweet taste, although it was not directly related to negative. Thus, the brain has established an indirect relationship between a banana smell and a sweet taste and an unpleasant irritation.
Researchers have shown that a amygdala -shaped body plays an important role in the formation of such indirect ties – the field of the brain responsible for emotional reactions, fear and anxiety. When tieting odors and tastes, the other parts of the brain interacting with almond -shaped body were activated.
If the activity of the almond -shaped body during the experiment was suppressed, mice could not establish indirect relationships. This indicates that this is the field of the brain that controls this process.
Scientists argue that such mechanisms work in humans.
