Research

We examine how moment-to-moment fluctuations in arousal and attention affect brain and cognition. There are 3 main themes:

  1. The role of the locus coeruleus-norepinephrine system in human cognition
  2. The effects of phasic and tonic arousal on information processing
  3. Moment-to-moment fluctuations in attention and cognitive control

We investigate these topics using behavioral methods, EEG, fMRI, pharmacology, pupillometry, patients studies and computational modeling.
