Our lab studies perception of sound location, speech, and music and how auditory processing is affected by attention and memory demands. Recent work is also examining interactions between the auditory system and association and motor systems. In addition, we use the auditory system as a model for understanding cognitive and neurobiological changes that accompany normal aging and dementing disorders such as Alzheimer's disease.
Many experiments in our lab monitor the brain's electrical activity using event-related potentials and EEG techniques while subjects perform cognitive tasks. We have also recently incorporated transcranial magnetic and electrical (direct current) stimulation techniques as a way to transiently influence brain activity. The impact of neural stimulation is assessed using behavioral and neuroelectric measures.
