Changes in Brain Resting-state Functional Connectivity Associated with Peripheral Nerve Block: A Pilot Study.
Melton, M Stephen; Browndyke, Jeffrey N; Harshbarger, Todd B; Madden, David J; Nielsen, Karen C; Klein, Stephen M (Anesthesiology, 2016-08)BACKGROUND: Limited information exists on the effects of temporary functional deafferentation (TFD) on brain activity after peripheral nerve block (PNB) in healthy humans. Increasingly, resting-state functional connectivity ... -
Differentiating sensitivity of post-stimulus undershoot under diffusion weighting: implication of vascular and neuronal hierarchy.
Harshbarger, Todd B; Song, Allen W (PLoS One, 2008-08-13)The widely used blood oxygenation level dependent (BOLD) signal during brain activation, as measured in typical fMRI methods, is composed of several distinct phases, the last of which, and perhaps the least understood, is ... -
Longitudinal Changes in Regional Cerebral Perfusion and Cognition Following Cardiac Surgery.
Smith, Patrick J; Browndyke, Jeffrey N; Monge, Zachary A; Harshbarger, Todd B; James, Michael L; Gaca, Jeffrey G; Alexander, John H; ... (12 authors) (The Annals of thoracic surgery, 2018-09-22)Cardiac surgery has been associated with increased risk of postoperative cognitive decline, as well as dementia risk in the general population. Few studies, however, have examined the impact of coronary revascularization ... -
Neural activation for actual and imagined movement following unilateral hand transplantation: a case study.
Madden, David J; Melton, M Stephen; Jain, Shivangi; Cook, Angela D; Browndyke, Jeffrey N; Harshbarger, Todd B; Cendales, Linda C (Neurocase, 2019-09-24)Transplantation of a donor hand has been successful as a surgical treatment following amputation, but little is known regarding the brain mechanisms contributing to the recovery of motor function. We report functional magnetic ... -
Resting-State Functional Connectivity and Cognition After Major Cardiac Surgery in Older Adults without Preoperative Cognitive Impairment: Preliminary Findings.
Browndyke, Jeffrey N; Berger, Miles; Harshbarger, Todd B; Smith, Patrick J; White, William; Bisanar, Tiffany L; Alexander, John H; ... (11 authors) (J Am Geriatr Soc, 2017-01)OBJECTIVES: To look for changes in intrinsic functional brain connectivity associated with postoperative changes in cognition, a common complication in seniors undergoing major surgery, using resting-state functional magnetic ... -
Task-related changes in degree centrality and local coherence of the posterior cingulate cortex after major cardiac surgery in older adults.
Browndyke, Jeffrey N; Berger, Miles; Smith, Patrick J; Harshbarger, Todd B; Monge, Zachary A; Panchal, Viral; Bisanar, Tiffany L; ... (14 authors) (Hum Brain Mapp, 2017-11-21)OBJECTIVES: Older adults often display postoperative cognitive decline (POCD) after surgery, yet it is unclear to what extent functional connectivity (FC) alterations may underlie these deficits. We examined for postoperative ...
