Gulf War Illness Associated with Abnormal Auditory P1 Event-Related Potential: Evidence of Impaired Cholinergic Processing Replicated in a National Sample
(Elsevier Ireland Ltd, 2018-11-10)Our team previously reported event-related potential (ERP) and hyperarousal patterns from a study of one construction battalion of the U.S. Naval Reserve who served during the 1991 Persian Gulf War. We sought to replicate ... -
Event-Related Neural Oscillation Changes Following Reasoning Training in Individuals with Mild Cognitive Impairment
(Elsevier Science B.V., 2018-10-17)Emerging evidence suggests cognitive training programs targeting higher-order reasoning may strengthen not only cognitive, but also neural functions in individuals with Mild Cognitive Impairment (MCI). However, research ... -
Gamma Oscillations During Episodic Memory Processing Provide Evidence for Functional Specialization in the Longitudinal Axis of the Human Hippocampus
(Wiley, 2018-11-05)The question of whether the anterior and posterior hippocampus serve different or complementary functional roles during episodic memory processing has been motivated by noteworthy findings in rodent experiments and from ... -
ASL-MRICloud: An Online Tool for the Processing of ASL MRI Data
(Wiley, 2018-12-26)Arterial spin labeling (ASL) MRI is increasingly used in research and clinical settings. The purpose of this work is to develop a cloud-based tool for ASL data processing, referred to as ASL-MRICloud, which may be useful ... -
Enhancement of Electromagnetic Interference Shielding Effectiveness with Alignment of Spinnable Multiwalled Carbon Nanotubes
(Pergamon-Elsevier Science Ltd, 2018-10-23)This research develops a unique material to attenuate electromagnetic interference (EMI) by using spinnable multiwalled carbon nanotubes (MWNTs) combined with bio-polydimethylsiloxane (PDMS) that contains BaTiO₃ (MBPBT). ... -
The Time Course of Semantic and Relational Processing During Verbal Analogical Reasoning
(Academic Press Inc Elsevier Science, 2018-12-01)Analogy is an important ability that allows humans to discover relationships between information domains that often vary in surface and relational characteristics. Cognitive neuroscience studies of analogy have demonstrated ... -
Frontostriatal White Matter Connectivity: Age Differences and Associations with Cognition and BOLD Modulation
(Elsevier Inc., 2020-06-07)Despite the importance of cortico-striatal circuits to cognition, investigation of age effects on the structural circuitry connecting these regions is limited. The current study examined age effects on frontostriatal white ... -
Genetic Predisposition for Inflammation Exacerbates Effects of Striatal Iron Content on Cognitive Switching Ability in Healthy Aging
(Academic Press Inc Elsevier Science, 2018-10-25)Non-heme iron homeostasis interacts with inflammation bidirectionally, and both contribute to age-related decline in brain structure and function via oxidative stress. Thus, individuals with genetic predisposition for ... -
Geofog4health: A Fog-Based SDI Framework for Geospatial Health Big Data Analysis
(Springer Heidelberg, 2018-02-21)Spatial Data Infrastructure (SDI) is an important framework for sharing geospatial big data using the web. Integration of SDI with cloud computing led to emergence of Cloud-SDI as a tool for transmission, processing and ... -
The Relationship Between Age, Neural Differentiation, and Memory Performance
(Society for Neuroscience, 2018-11-02)Healthy aging is associated with decreased neural selectivity (dedifferentiation) in category-selective cortical regions. This finding has prompted the suggestion that dedifferentiation contributes to age-related cognitive ... -
The Antidiabetic Drug Metformin Prevents and Reverses Neuropathic Pain and Spinal Cord Microglial Activation in Male but not Female Mice
(Academic Press Ltd- Elsevier Science Ltd, 2018-11-01)Metformin is a widely prescribed drug used in the treatment of type II diabetes. While the drug has many mechanisms of action, most of these converge on AMP activated protein kinase (AMPK), which metformin activates. AMPK ... -
Some Prospective Alternatives for Treating Pain: The Endocannabinoid System and its Putative Receptors GPR18 and GPR55
(Frontiers Media SA, 2019-01-08)Background: Marijuana extracts (cannabinoids) have been used for several millennia for pain treatment. Regarding the site of action, cannabinoids are highly promiscuous molecules, but only two cannabinoid receptors (CB₁ ... -
Functional Performance of a Millimeter Wave Square Holey Dielectric Waveguide
