I also saw Brian Knutson speak at Stanford recently.
Brian is interested in the neural basis of emotion and runs the Symbiotic Project on Affective Neuroscience. (Psychologists use the word “affect” to describe mood states and personality traits characterized both by high arousal and either positive or negative valence.)
Brian is also interested in the convergence of disciplines brought about by his research. I’m going to see if I can speak with him about design.
