Our research

We employ the methods of neuropsychology, electrophysiology, and combinations of the two. Neuropsychology is the experimental study of the cognitive abilities of patients with acquired brain damage, whereas electrophysiology refers to the use of event-related potentials (ERPs) to gain insight into the neural bases of cognition.

Traumatic brain injury (TBI) and post-traumatic stress disorder (PTSD)

The CNE lab is currently researching the effects of mild traumatic brain injury (TBI) and post-traumatic stress disorder (PTSD). We are interested in separating out the symptoms of these two conditions, which are frequently seen together in veterans who served in Afghanistan (OEF) or Iraq (OIF). This study, "The separate and cumulative effects of TBI and PTSD on cognitive function and emotional control," is funded by the U.S. Department of Defense and the U.S. Army Medical Research and Materiel Command.

We are also researching the effects of moderate to severe TBI, in addition to other neurological conditions such as stroke. This study, "Frontal lobe injury and executive control of cognition and emotion," is funded by the U.S. Department of Veterans Affairs.

These projects use a combination of behavioral and event-related potential (ERP) methods.

Recruitment flier for people with TBI, PTSD, or both TBI and PTSD

Recruitment flier for healthy people interested in participating as controls

Language and aphasia

We continue to research language and aphasia using a combination of behavioral and ERP methods. Specific areas of interest include:

Acquired disorders of reading (alexia) and writing (agraphia)
Relationships between morphological, phonological, and semantic processing in aphasia
Perceptual and propositional approaches to conceptual representation
Executive components of language

Executive control and frontal lobe functions

All of these projects inform the CNE Lab's general interest in executive control and frontal lobe functions, especially:

The anterior cingulate cortex and executive control
Relationships between executive function and emotion
Electrophysiological measures of error monitoring (the ERN and Feedback Negativity)
