Aci-35 And Aadvac1 Active Immunotherapy As Preventative Treatment Options For Chronic Traumatic Encephalopathy, Emily C. Boehlein Oct 2020

Aci-35 And Aadvac1 Active Immunotherapy As Preventative Treatment Options For Chronic Traumatic Encephalopathy, Emily C. Boehlein

Selected Honors Theses

One of the most common, as well as one of the most dangerous injuries amongst athletes today is mild traumatic brain injury (mTBI), commonly known as concussion. Aside from physical symptoms such as nausea, dizziness, and headaches; concussions have can have longterm effects on brain physiology. A common neurological disease that can result from multiple concussions is Chronic Traumatic Encephalopathy (CTE), characterized by symptoms such as severe depression, anxiety, confusion, and aggression; amongst others.1 On the cellular level, CTE is classified by a unique pathway that leads to the hyperphosphorylation of tau protein and subsequent clumping of tau-containing neurofibrillary tangles …

Optimizing Preprocessing Of Fmri Data To Maximize Correspondence Of Functional Anatomy Across Individuals, Nargess Ghazaleh

Electronic Thesis and Dissertation Repository

In movie-activation fMRI, intersubject correlation (ISC) indicates a functional correspondence across viewers. Brains di↵er in shape; spatial normalization and smoothing enhance inter-subject functional overlap. We compare three normalization methods and six smoothing levels to discover which method yields the best functional overlap, indexed by ISC. This is key to optimizing data analysis in clinical studies using movie-activation fMRI in future. In a 3T scanner, 44 healthy subjects watched an 8-min movie. Both normalization and smoothing a↵ected the strength and extent of the ISC. ISC values were more robust for ANTs and DARTELthanforSPM12andwere(asymptotically)thestrongestat12mmsmoothing. When image data are preprocessed with high-dimensional volumetric …
