About the Lab
Research in the TU Cognitive Neurophysiology Laboratory is broadly directed to advancing our understanding of the neurobiological basis of language. This work integrates neuropsychological, neurophysiological, and functional neuroimaging approaches to understanding the neural correlates of language processing. We primarily use three modalities of investigation: Event-related potentials (ERP) derived from recordings of electroencephalographic (EEG) activity, functional magnetic resonance imaging (fMRI), and traditional behavioral testing.
Neurobehavioral testing is a non-invasive way to test participants' accuracy and response to a given task. Examiners would ask participants to respond to a given task then record and analyze the data. This gives us an idea of how the brain responds to different assignments.
Event-related potentials (ERPs) are based on electroencephalography (EEG) recordings where the brain’s electrical activity is recorded while participants perform certain tasks. An array of electrodes are placed on the participant’s scalp to collect the brain's responses to tasks such as listening to words, making a decision about the nature of a sound, or looking at pictures.
fMRIs acquire images of the brain's increased blood flow to certain areas during a performed task. Every few seconds the flow of blood can be tracked and we can observe what areas of the brain are fed more oxygen during specific tasks. In order to ensure that the area in question is being activated by the task, participants are also asked to perform a control task. This allows researchers to see if a portion of the brain is specialized for the task at hand.
