Anxiety and depression are highly prevalent, recurrent, and major public health problems. Decades of research has uncovered associations between symptom dimensions of anxiety and depression and abnormal neural activation across executive control-, threat-, and reward-related networks. Recent studies have developed a hierarchical symptom structure of anxiety and depression termed the...
Individuals following a stroke suffer from a host of movement impairments that affect the upper extremity. Hand use is often significantly compromised, especially in individuals with more severe impairments, which makes it difficult for individuals to participate in activities of daily living. One of the major goals of rehabilitation is...
Rhythmic fluctuations of electrical activity in the brain provide insights into the proposed mechanism by which we encode experiences and then maintain, forget, modify, and retrieve them. Yet there is still much to learn about how neural oscillations relate to memory function. The purpose of this research is to discover...
The objective of this study was to investigate how brain plasticity can be expressed following injury to the nervous system. This plasticity can occur after either direct injury to the brain, such as in hemiparetic stroke, or injury to the peripheral nerves, such as in upper-limb amputation. In order to...
Learning to play an instrument requires the progressive tuning almost all of a student's senses. He trains his ears to hear consonance and dissonance and eyes to read sheet music or read other musicians' body language, for example. The protracted training that is required to become a musician has been...
Anxiety disorders are the most common group of mental illnesses in the United States and affect over 15% of the population. Prior work utilizing electroencephalogram (EEG) to investigate event-related potentials (ERPs) from the scalp has shown success in isolating certain neural correlates related to increased risk for developing anxiety disorders....
