“Consciousness studies is often confusing and unruly,” says Wu. “I think it critical to highlight clear questions about consciousness that science can answer.”
In the article, Wu focuses on two basic questions. First, what differentiates states that are conscious from those that are not, what is called generic consciousness. Second, in a conscious state, what determines what one is conscious of, what is called specific consciousness. “These concrete questions provide an organizing principle for empirical research,” Wu continues. “There is a lot of illuminating work done that has helped us understand facets of consciousness, including here at the CNBC.”
For example, work by CNBC faculty members Julie Fiez and Avniel Ghuman have probed the role of the left midfusiform gyrus (lmFG) in word recognition and individuation, and demonstrated disruption of awareness of words by modulating activity in lmFG. “These sorts of direct manipulation, based on our understanding of underlying functional circuity and information processing, will be crucial to explaining specific conscious awareness,” Wu concludes.
