Multimodal Neuroimaging Of Hiv And Aging, Brandon Lew
Multimodal Neuroimaging Of Hiv And Aging, Brandon Lew
Theses & Dissertations
HIV infection remains a significant contributor to disease burden, and with the success of antiretroviral therapies, the population of people with HIV is aging. A growing literature suggests a relationship between HIV-infection and a profile of age advancement, most notably in molecular studies of epigenetics. However, despite the widely-known high prevalence of HIV-related brain atrophy, functional deficits, and HIV-associated neurocognitive disorder (HAND), epigenetic age advancement has not been linked to HIV-related changes in neuroimaging metrics.
We applied three neuroimaging methods, structural MRI, resting state functional MRI, and resting state MEG, to study the brain structure and function of 121 virally-suppressed …
Beyond The Eye: The Neural Signature Of Cerebral Visual Processing In Children With Cerebral Palsy, Jacy R. Hannan
Beyond The Eye: The Neural Signature Of Cerebral Visual Processing In Children With Cerebral Palsy, Jacy R. Hannan
Theses & Dissertations
Cerebral palsy (CP) is a permanent, non-progressive neuromuscular disorder diagnosed early in childhood. Frequently the lesion that causes the motor impairments in individuals with CP concurrently disrupts the visual networks, placing them at a high risk of cerebral visual dysfunctions. Cerebral visual impairment (CVI) often remains unrecognized or misdiagnosed in people with CP. Despite the crucial role of visual function in the development of movement and cognition, the neurophysiological basis of the cerebral visual dysfunctions is almost entirely unknown. This investigation aimed to examine the neurophysiological mechanisms underlying cerebral visual dysfunction in children with CP. Specifically, this research used magnetoencephalographic …
