Surprise induced changes in behaviour and brain dynamics
|Date/Time:||Wednesday 8 June 2011, 4.30pm|
|Location:||SW101 (Brian Spratt room) in Computing|
In this talk I will present a number of studies that show how surprising events, or violations of expectations, change our behaviour and brain responses. In particular, I will show that: 1) an incidental surprising stimulus not only slows down behavioural responses, but also reduces sensitivity in perceptual decisions, 2) rule violation evokes a conspicuous brain response that can be predicted by a hierarchical network model, which exhibits recurrent dynamics amongst cortical regions, and 3) a biological salient context can enhance responses to surprising information. This information might first engage a subcortical pathway, and then engage a cortical pathway after a delay.
