Author and scientist Antonio Damasio gives a presentation in this TED video about consciousness. Damasio has developed a model which explains how certain features of consciousness and particularly emotions can result from a sophisticated mapping of visceral sensation in brain regions such as the Insular Cortex. Indeed this work has been developed further both by Damasio himself and neuroscientist A Craig and formed some of the early reading that was used for developing a model of the Insular Cortex on this blog. The interested reader can read further on this in the Appendix. In the video, Damasio begins by discussing the very big topic of consciousness and explaining just how significant this is for us. Consciousness is used to explain the nature of our selves, pathological conditions such as the vegetative state as well as features of our visual experience. Damasio raises a number of interesting questions for the audience to consider and suggests three forms of consciousness – Proto, Core and Autobiographical. He goes onto to suggest that animals share many aspects of our conscious experiences and that some animals including primates and dogs would experience autobiographical consciousness. This he goes onto explain results from our lived past and anticipated future and forms the basis for other phenomenon including creativity and culture. This is a short but interesting video featuring a neuroscience icon.
