Mapping Of Auditory Cortical Functions Using Electrocorticography, James Robert Swift
Mapping Of Auditory Cortical Functions Using Electrocorticography, James Robert Swift
Legacy Theses & Dissertations (2009 - 2024)
Communication is a dynamic process through which we translate our inner thoughts in such a way that they can be shared with another person. This complex neurological phenomenon is a key predictor of our productivity and health. When our ability to communicate is compromised, our quality of life suffers. Although numerous methods to investigate the neuroscientific underpinnings of human language exist, our understanding of this process remains incomplete. Improving our understanding of where, when, and how auditory cortical activity occurs can enhance diagnostic techniques and improve treatment methods for neurological conditions that can impact auditory processing, such as epilepsy, or …
The Brain's Large-Scale Electrophysiological Signals : Fundamental Attributes And Neurosurgical Applications, Mohammad Amin N/A Nourmohammadi
The Brain's Large-Scale Electrophysiological Signals : Fundamental Attributes And Neurosurgical Applications, Mohammad Amin N/A Nourmohammadi
Legacy Theses & Dissertations (2009 - 2024)
Brain’s electrophysiological signals are most certainly the ultimate source for studying the sophisticated neural network inside our cranium. The unparalleled complexity of these biosignalsis the quintessential manifestation of their underlying complicated neurophysiological processes. Studying brain signals on the cellular level provides valuable information regarding the brain’s electrophysiology on the small-scale. However, it is the remarkable network in the large-scale that gives rise to the brain’s extraordinary attributes and exceptional capabilities—perception, cognition, computation, and consciousness are all the emergent byproducts of the dynamic neuronal interactions on the network level. In this sense, the large-scale electrophysiological signals, recorded from the surface of …
Statistical Methods To Unravel Cortical Mechanism Of Perception And Response To Auditory Stimuli, Ladan Moheimanian
Statistical Methods To Unravel Cortical Mechanism Of Perception And Response To Auditory Stimuli, Ladan Moheimanian
Legacy Theses & Dissertations (2009 - 2024)
Behavioral responses to auditory stimuli have a critical role in our daily activities. The perception of these stimuli and the generation of appropriate behavioral responses requires the interaction of thousands of neurons in the auditory-motor pathways in the brain. Despite their importance, still many neuroscientific questions about these interactions are remained to be answered. This may result from the limitations of brain recordings as well as statistical methods to analyze brain recordings. In this dissertation, I investigated underlying mechanisms that govern these neural interactions in the auditory-motor pathways using novel statistical techniques applied to the brain recordings from the surface …
Harnessing Electrocorticographic Signals For Neuroscience And Neurosurgery, Adriana De Pesters
Harnessing Electrocorticographic Signals For Neuroscience And Neurosurgery, Adriana De Pesters
Legacy Theses & Dissertations (2009 - 2024)
Daily human activities, such as speaking, driving or listening to music, are produced by activations of neurons in the brain. Where, when and how these activations occur has been the subject of intense debate for the last decades. Traditional techniques to image the human brain, such as functional magnetic resonance imaging (fMRI) or electroencephalography (EEG), only provide limited information regarding where and when these activations take place. For that reason, critical information is currently missing regarding how neurons from different parts of the brain interact and coordinate their activity to implement behavior. This information is critical to understand human behavior …
Separating The Signal From The Noise In Electrocorticographic (Ecog) Signals : Novel Analytic Methods And Their Application To Experimental And Theoretical Neuroscience, William Grey Coon
Separating The Signal From The Noise In Electrocorticographic (Ecog) Signals : Novel Analytic Methods And Their Application To Experimental And Theoretical Neuroscience, William Grey Coon
Legacy Theses & Dissertations (2009 - 2024)
Measurements are comprised of two parts: signal, that is, the true quantity one wishes to measure, and noise, that is, measurement fluctuations that are unrelated to the true signal.
