Initially, the posterior part of the insula (see pictures) processes these sensory inputs as subconscious body sensations that have little or no emotional component. These sensations are soon re-represented, however, in the mid-insula and then in the anterior insula to become subjective, emotion-based sensations. If strong enough, they become felt emotions—such as sadness or joy—as they interact with the anterior cingulate, prefrontal cortices, and other areas.
Schappelle: The insula, center, connects to many different regions within the brain, which are noted in black text.
