In previous posts in the series (see Appendix) we began with an open model of the Insular Cortex (i.e one which can be contributed to by the readers). This is illustrated at the top of the diagram above where the details of the model were based on an interpretation of the research literature. Along the way we then looked at a detailed model by Craig outlining a possible role for the Insular Cortex in awareness. Then to contextualise this we looked at more general models of the emotions by scientists such as Darwin, MacLean, James and Cannon. The diagram above shows these three parts separately reflecting the discussion to date. Damasio’s model has not been explored in any depth and in the previous posts Craig’s model has received the most attention although he has expanded his work since the paper we examined earlier. MacLean’s model is amongst the most complex here. MacLean integrated the models of Papez, Klüver-Bucy as well as Cannon and Bard.
We have now reached the stage where it is possible to begin to integrate the open model with other models considered above. The key problem in developing a model of emotional regulation is understanding the role that a single brain region might play in this. In order to do this it is necessary to have an understanding of other brain regions that are thought to play a role in emotional regulation. Along the way it will be necessary to explore some of these other models in more detail.
