Neural Plausibility of Bayesian Inference
(University of Waterloo, 2018-07-31)Behavioral studies have shown that humans account for uncertainty in a way that is nearly optimal in the Bayesian sense. Probabilistic models based on Bayes' theorem have been widely used for understanding human cognition, ... -
The Neural Processes of Perceived Simultaneity and Temporal Order in Younger and Older Adults using EEG.
(University of Waterloo, 2017-08-02)In order to make sense of the world, the central nervous system (CNS) must determine the temporal order of events and integrate cues that belong together. The process of integrating information from multiple sensory ... -
Neural processing of fearful and happy facial expressions during emotion-relevant and emotion-irrelevant tasks: A fixation-to-feature approach
(Elsevier, 2016-09-01)Research suggests an important role of the eyes and mouth for discriminating facial expressions of emotion. A gaze-contingent procedure was used to test the impact of fixation to facial features on the neural response to ... -
Neural Processing of Fearful and Happy Facial Expressions: Effects of Fixation to Facial Features and Task Demands
(University of Waterloo, 2015-11-25)The current literature regarding the time course of facial expression processing is inconsistent and early emotion effects are debated. Facial expressions are well-known to be characterized by “diagnostic” facial features ... -
The neural systems for perceptual updating
(Elsevier, 2018-04-01)In a constantly changing environment we must adapt to both abrupt and gradual changes to incoming information. Previously, we demonstrated that a distributed network (including the anterior insula and anterior cingulate ... -
Neural Text Generation from Structured and Unstructured Data
(University of Waterloo, 2019-08-28)A number of researchers have recently questioned the necessity of increasingly complex neural network (NN) architectures. In particular, several recent papers have shown that simpler, properly tuned models are at least ... -
Neural Tube Defect-causing Teratogens Affect Tissue Mechanical Properties and Cytoskeletal Morphology in Axolotl Embryos
(University of Waterloo, 2007-11-22)The teratogenic drugs cytochalasin B and valproic acid have been shown to alter F-actin polymerization, an effect that is crucial in forming microfilaments. Microfilaments form important cytoskeletal structures that maintain ... -
Neural-guidance for symbolic reasoning
(University of Waterloo, 2020-10-19)Symbolic reasoning begot Artificial Intelligence (AI). With the recent advances in Deep Learning, many traditional AI areas such as Computer Vision and Natural Language Processing have moved to probabilistic-based approaches. ... -
Neuregulin’s role in regulating the anti-inflammatory pathway
(University of Waterloo, 2009-08-12)Inflammation can be up-regulated by microglia and macrophages through the release of pro-inflammatory cytokines such as tumour necrosis factor-alpha (TNF-α). Excess production of TNF-α can lead to a variety of diseases and ... -
A Neurocomputational Model of Smooth Pursuit Control to Interact with the Real World
(University of Waterloo, 2014-01-24)Whether we want to drive a car, play a ball game, or even enjoy watching a flying bird, we need to track moving objects. This is possible via smooth pursuit eye movements (SPEMs), which maintain the image of the moving ... -
A neurocomputational model of the mammalian fear conditioning circuit
(University of Waterloo, 2013-09-24)In this thesis, I present a computational neural model that reproduces the high-level behavioural results of well-known fear conditioning experiments: first-order conditioning, second-order conditioning, sensory preconditioning, ... -
Neuromuscular Clinical Decision Support using Motor Unit Potentials Characterized by 'Pattern Discovery'
(University of Waterloo, 2009-01-21)Objectives: Based on the analysis of electromyographic (EMG) data muscles are often characterized as normal or affected by a neuromuscular disease process. A clinical decision support system (CDSS) for the electrophysiological ... -
Neuromuscular Control of Gait and Squatting Following a Simulated Occupational Kneeling Exposure
(University of Waterloo, 2016-01-20)Frequent and prolonged occupational high knee flexion postures such as kneeling and squatting are associated with an increased risk for the initiation and development of knee osteoarthritis. In order to reduce the prevalence ... -
Neurophysiological mechanisms of motor cortical modulation associated with bimanual movement
(University of Waterloo, 2008-09-11)The neural correlates of bilateral upper limb movement are poorly understood. It has been proposed that interhemispheric pathways contribute to the modulation of motor cortical excitability during bimanual movements, ... -
Neutral Radicals as Strongly Correlated Materials: Insights from Theory and Experiment
(University of Waterloo, 2014-12-19)Neutral organic radicals have been pursued for conductive and magnetic solid state properties associated with their unpaired electron. Historically, synthetic challenges and design limitations restricted these materials ... -
Neutron interferometer crystallographic imperfections and gravitationally induced quantum interference measurements
(American Physical Society, 2017-01-25)Dynamical diffraction leads to an interesting, unavoidable set of interference effects for neutron interferometers. This experiment studies the interference signal from two and three successive Bragg diffractions in the ... -
Neutron interferometric measurement of the scattering length difference between the triplet and singlet states of n-He-3
(American Physical Society, 2014-12-15)We report a determination of the n-He-3 scattering length difference = b = = b = 1 -b = 0 = [-5.411 = 0.031 (statistical) = 0.039 (systematic)] fm between the triplet and singlet states using a neutron interferometer. This ... -
Neutron Interferometry at the National Institute of Standards and Technology
(Hindawi, 2015)Neutron interferometry has proved to be a very precise technique for measuring the quantum mechanical phase of a neutron caused by a potential energy difference between two spatially separated neutron paths inside ... -
Neutron limit on the strongly-coupled chameleon field
(American Physical Society, 2016-03-11)The physical origin of the dark energy that causes the accelerated expansion rate of the Universe is one of the major open questions of cosmology. One set of theories postulates the existence of a self-interacting scalar ... -
Neutron Scattering Investigations of Three-Dimensional Topological States
(University of Waterloo, 2023-11-13)Topological magnets represent a unique class of quantum materials in which a nontrivial Berry curvature in real- or momentum-space couples to the magnetic properties of the topological electronic or spin system. Magnetic ...
