Alterations in brain connectivity after spinal cord injury using functional MRI
… biomarkers that can be used to characterize SCI. Altered functional connectivity in the brain has been observed in a number of neurological patient populations. Hence, it was hypothesized that such alterations in brain connectivity occurs after SCI as well. In this study, functional magnetic …

DTI-based tractographic analysis of white matter alterations in HIV infected children
… Often, there is a link between structural and functional abnormalities. Previously, we found HIV-associated changes in white matter and functional networks in a cohort of 7-year-old HIV infected (HIV+) children who intiatied early cART compared to uninfected controls. To explore possible …

Tau pathology, microglia activation, and network dysfunction in Alzheimer’s disease
… (indexing in vivo neuroinflammation), with 2) connectivity measures of resting-state functional magnetic resonance imaging. I found increased [18F-AV]-1451 binding (reflecting tau pathology) in AD patients, relative to controls, in the medial/lateral temporal and parietal cortices. In terms of …

Effects of bipolar disorder on intrinsic brain networks
… with prefrontal and/or limbic dysfunction. Functional Magnetic Resonance Imaging (fMRI) allows identification of intrinsic brain networks (IBN), like the default mode network (DMN) and executive control network (ECN), which are consistent with previously established functional and anatomical …

CHOLINERGIC CONTRIBUTIONS TO EMOTION REGULATION
… receptors in vivo; (2) procaine alters functional connectivity among cholinergic brain regions and their targets; and (3) procaine-induced emotions are related to core cholinergic regions. In Experiment I, anesthetized rhesus monkeys underwent positron emission tomography (PET) studies …
