The Sophie Scott talk about laughter is on the science behind why people laugh. Based in Britain, the neuroscientist presently works as the Deputy Director of the Institute of Cognitive Neuroscience at University College London.
In terms of the speaker's current research and academic interests, she is concerned with the neurobiology of the perception of speech, which is also referenced in the Sophie Scott talk. According to her UCL ICN bio, this includes "the functional sub systems in human auditory cortex, the evolution of speech, the difference between intelligibilty and comprehension, and profiles of recovery in aphasia." She is also participating in a project examining reading and rehabilitation in hemianopic alexia. Her work has been published in a vast number of academic articles.
