Description:: This thesis focuses on the development of a cochlear implant (CI) that uses photons to stimulate surviving auditory neurons in severe-to-profoundly deaf individuals. The benefit of optical over electrical stimulation is its spatial selectivity with the potential to create significantly more independent channels to encode acoustic information and likely enhances...

Description:: Recent studies have begun to examine white matter connectivity aberrations in psychiatric populations, such as major depressive disorder. Several studies have found reduced white matter integrity (WMI) in depressed samples, though the location of this reduction is not clear. Incorporating symptom measures of depression severity and rumination may allow for...

Description:: 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...

Description:: Dynamic decision-making is a complex process that relies on our ability to generate, evaluate and implement a variety of strategies. Understanding how people navigate this process is a difficult problem that requires a wide range of methodologies. This study details a combination of behavioral experiments, computational modeling, and neuroimaging that...

Description:: Interactions between working memory and long term memory systems are still not well understood, as the systems have long been thought to be mostly separate. An interesting intersection of these memory systems is domain-specific expertise, whereby individuals are able to show supra-span memory for information related to the area of...

Description:: 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...

Description:: Conversation is an important part of human life. Given globalization and the numerous languages around the world, it is increasingly likely that we will be communicating with others speaking in their second language (L2) rather than their first language (L1). In these situations, communication may require more effort. However, people...
