Almost 5 years ago, we looked at a model of the Insular Cortex that started with a few assumptions from some papers which included one looking at GABA receptors in the Insular Cortex and anxiety. Along the way we looked at works by Antonio Damasio and A.Bud.Craig. More recently we have looked at other areas of the brain implicated in our emotional experiences as well as some of the influential models of the Limbic System.
Returning to the beginning and looking at how to build such a model it seems sensible to contextualise the model in terms of the most influential theories in this area. William James and Carl Lange raised the question of whether we first experience physiological reactions and then emotions whilst in the Cannon-Bard theory the reverse is stated. In either case there is a stated connection between physiological reactions to events and emotions.
These physiological reactions in the body produce information. The process of responding to this information is interoception. The Insular Cortex receives interoceptive input from the body leading to a posited role in interoception. Referring to the discussion above we can see that the Insular Cortex is therefore a natural point of enquiry for exploring the relationship between physiological responses to events and our emotional experiences.
