Do sensory metaphors give language emotional flavor?

Metaphorical sentences may spark increased brain activity in emotion-related regions because they allude to physical experiences …

Could the relationships among physical, emotional, and linguistic processing reflect deeper levels of integration among the cognitive processes of perception, association, and conception?
