Our lab collects EEG data to answer questions about how the brain processes faces, about how sleep affects brains, and how the brains of people with Parkinson's disease and Multiple Sclerosis are affected.

The impact of sleep loss on sustained and transient attention: an EEG study

Sleep restriction affects attention in different ways. Performance on an attentional blink task was unaffected by sleep restriction in two studies, but performance on a vigilance task was affected in both. In the second study, we looked at resting state EEG and found alpha was reduced after sleep restriction, which may have balanced out performance on the attentional blink task.

Striatal morphology correlates with frontostriatal electrophysiological motor processing in Huntington's disease: an IMAGE-HD study

**Background:** Huntington's disease (HD) causes progressive atrophy to the striatum, a critical node in frontostriatal circuitry. Maintenance of motor function is dependent on functional connectivity of these premotor, motor, and dorsolateral …

Abnormal electrophysiological motor responses in Huntington’s disease: evidence of premanifest compensation

**Background** Huntington's disease (HD) causes progressive motor dysfunction through characteristic atrophy. Changes to neural structure begin in premanifest stages yet individuals are able to maintain a high degree of function, suggesting …

Atypical Motor Response Potentials (MRPs) in Symptomatic Huntington’s Patients During Simple Movements

## Background Huntington's Disease causes progressive motor dysfunction through atrophic disruption to the frontal cortical motor circuitry and basal ganglia regions. Symptom onset typically begins at age 40; subsequent neurodegeneration is …
