Coherence between cortex and subthalamic nucleus

We discovered that theta coherence between cortex and subthalamic nucleus (STN) for left hemisphere deep brain stimulation (DBS) implant increases during speech. The theta coherence for right hemisphere DBS is not as pronounced compared to rest.

In collaboration with Rachel Smith, Victor Del Bene, Matthew Nelson, Joe Olson, Sarah Brinkerhoff, Zach Irwin, Nicole Bentley, Robert Knight, and Harrison Walker.

Spirometry function based COPD detection and staging

Wikipedia states that Spirometry (meaning the measurement of breath) is the most common of the pulmonary function tests, measuring lung function, specifically the amount (volume) and/or speed (flow) of air that can be inhaled and exhaled. Spirometry is an important tool used for generating pneumotachographs, which are helpful in assessing conditions such as asthma, pulmonary fibrosis, cystic fibrosis, and Chronic obstructive pulmonary disease (COPD).

Presently accepted methods for COPD are based on the selection of a few specific points from the output graph and they are not reliable enough. In this project, we develop additional more robust measures for staging COPD.
