A 4-year longitudinal neuroimaging study of cognitive control using latent growth modeling: developmental changes and brain-behavior associations
(2021-08-15)Despite theoretical models suggesting developmental changes in neural substrates of cognitive control in adolescence, empirical research has rarely examined intraindividual changes in cognitive control-related brain ... -
A 52-Year-Old HIV-Positive Man with Abdominal Pain
(Hindawi, 2015-01-01) -
A Molecular Mechanism Regulating the Timing of Corticogeniculate Innervation
(Elsevier, 2013-11-14)Neural circuit formation demands precise timing of innervation by different classes of axons. However, the mechanisms underlying such activity remain largely unknown. In the dorsal lateral geniculate nucleus (dLGN), axons ... -
Aberrant early growth of individual trigeminal sensory and motor axons in a series of mouse genetic models of 22q11.2 deletion syndrome
(2020-09-15)We identified divergent modes of initial axon growth that prefigure disrupted differentiation of the trigeminal nerve (CN V), a cranial nerve essential for suckling, feeding and swallowing (S/F/S), a key innate behavior ... -
Aberrant placental immune parameters in the feline immunodeficiency virus (FIV)-infected cat suggest virus-induced changes in T cell function
(2013-07-19)Background Immune activity during pregnancy must be tightly regulated to ensure successful pregnancy. This regulation includes the suppression of inflammatory activity that could target the semi-allogeneic fetus. Tregs ... -
Access to Autism Spectrum Disorder Services for Rural Appalachian Citizens
(2020-01)Background: Low-resource rural communities face significant challenges regarding availability and adequacy of evidence-based services. Purposes: With respect to accessing evidence-based services for Autism Spectrum ... -
Accurate human microsatellite genotypes from high-throughput resequencing data using informed error profiles
(Oxford University Press, 2013-01)Repetitive sequences are biologically and clinically important because they can influence traits and disease, but repeats are challenging to analyse using short-read sequencing technology. We present a tool for genotyping ... -
Acetylcholine Receptor Activation as a Modulator of Glioblastoma Invasion
(MDPI, 2019-10-05)Grade IV astrocytomas, or glioblastomas (GBMs), are the most common malignant primary brain tumor in adults. The median GBM patient survival of 12–15 months has remained stagnant, in spite of treatment strategies, ... -
Active inference and agency: optimal control without cost functions
(Springer, 2012-08-03)This paper describes a variational free-energy formulation of (partially observable) Markov decision problems in decision making under uncertainty. We show that optimal control can be cast as active inference. In active ... -
Acutely enhancing affective state and social connection following an online dance intervention during the COVID-19 social isolation crisis
(2023-01-16)The COVID-19 pandemic has forced many throughout the world to isolate themselves from their respective communities to stop the spread of disease. Although this form of distancing can prevent the contraction of a virus, it ... -
Adenovirus transduction to express human ACE2 causes obesity-specific morbidity in mice, impeding studies on the effect of host nutritional status on SARS-CoV-2 pathogenesis
(Elsevier, 2021-11-01)The COVID-19 pandemic has paralyzed the global economy and resulted in millions of deaths globally. People with co-morbidities like obesity, diabetes and hypertension are at an increased risk for severe COVID-19 illness. ... -
The adhesion function of the sodium channel beta subunit (beta 1) contributes to cardiac action potential propagation
(2018-08-14)Computational modeling indicates that cardiac conduction may involve ephaptic coupling - intercellular communication involving electrochemical signaling across narrow extracellular clefts between cardiomyocytes. We ... -
Advances in Behavioral Remote Data Collection in the Home Setting: Assessing the Mother-Infant Relationship and Infant's Adaptive Behavior via Virtual Visits
(Frontiers, 2021-10-01)Psychological science is struggling with moving forward in the midst of the COVID-19 pandemic, especially due to the halting of behavioral data collection in the laboratory. Safety barriers to assessing psychological ... -
Aging into Perceptual Control: A Dynamic Causal Modeling for fMRI Study of Bistable Perception
(Frontiers, 2016-03-31)Aging is accompanied by stereotyped changes in functional brain activations, for example a cortical shift in activity patterns from posterior to anterior regions is one hallmark revealed by functional magnetic resonance ... -
Agrin and Synaptic Laminin Are Required to Maintain Adult Neuromuscular Junctions
(PLOS, 2012-10-03)As synapses form and mature the synaptic partners produce organizing molecules that regulate each other’s differentiation and ensure precise apposition of pre- and post-synaptic specializations. At the skeletal neuromuscular ... -
Alexithymic Trait and Voluntary Control in Healthy Adults
(PLOS, 2008-11-12)Background: Alexithymia is a personality trait characterized by deficiency in understanding, processing, or describing emotions. Recent studies have revealed that alexithymia is associated with less activation of the ... -
Almost Everything We Need to Better Serve Children of the Opioid Crisis We Learned in the 80s and 90s
(Frontiers, 2018-10-16)Opioid use disorder impedes dependent parents' abilities to care for their children. In turn, children may languish in unpredictability and persistent chaos. Societal responses to these children are often guided by a belief ... -
The ALS-inducing factors, TDP43A315T and SOD1G93A, directly affect and sensitize sensory neurons to stress
(Nature, 2018-11-08)There is increased recognition that sensory neurons located in dorsal root ganglia (DRG) are affected in amyotrophic lateral sclerosis (ALS). However, it remains unknown whether ALS-inducing factors, other than mutant ... -
Alterations in Brain Connectivity Underlying Beta Oscillations in Parkinsonism
(PLOS, 2011-08-11)Cortico-basal ganglia-thalamocortical circuits are severely disrupted by the dopamine depletion of Parkinson’s disease (PD), leading to pathologically exaggerated beta oscillations. Abnormal rhythms, found in several circuit ... -
Altered translation initiation of Gja1 limits gap junction formation during epithelial–mesenchymal transition
(The American Society for Cell Biology, 2018-02-13)Epithelial–mesenchymal transition (EMT) is activated during development, wound healing, and pathologies including fibrosis and cancer metastasis. Hallmarks of EMT are remodeling of intercellular junctions and adhesion ...
