Recovering steady‐state visual evoked potential‐related electroencephalography during amplitude‐modulated‐transcranial alternating current stimulation using dynamic adaptive stimulation artifact source separation

Journal of Intelligent Medicine, EarlyView.
Abstract Simultaneous electroencephalography (EEG) recording during transcranial alternating current stimulation (tACS) is strongly contaminated by stimulation artifacts, limiting direct assessment of neural activity. Steady‐state visual evoked potentials (SSVEPs) provide frequency‐specific and phase‐locked responses, making them suitable for ...

Using Physically-Modeled Synthetic Data to Assess Hyperspectral Unmixing Approaches

Remote Sensing, 2013
This paper considers an experimental approach for assessing algorithms used to exploit remotely sensed data. The approach employs synthetic images that are generated using physical models to make them more realistic while still providing ground truth ...

Temporal dynamics of visual awareness and target detection revealed by EEG‐based univariate and multivariate analyses

Journal of Intelligent Medicine, EarlyView.
In this study, we combined univariate ERP analysis with multivariate decoding of EEG data to examine target detection and reported visual awareness in a near‐threshold visual task. The results revealed partly overlapping yet distinguishable temporal dynamics associated with the two processes.

Optimizing Within-Subject Experimental Designs for jICA of Multi-Channel ERP and fMRI

Frontiers in Neuroscience, 2018
Joint independent component analysis (jICA) can be applied within subject for fusion of multi-channel event-related potentials (ERP) and functional magnetic resonance imaging (fMRI), to measure brain function at high spatiotemporal resolution (Mangalathu-

5.0 T Coronary Magnetic Resonance Angiography in Calcified Coronary Arteries: Diagnostic Performance Compared With Computed Tomography Using Invasive Angiography as Reference

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Coronary computed tomography angiography (CCTA) often overestimates stenosis in calcified plaques due to blooming artifacts. The performance of 5.0 T Coronary MR angiography (CMRA) in calcified arteries remains unclear. Purpose To assess plaque effects on 5.0 T CMRA image quality and compare diagnostic performance with CCTA.

Exploring the psychosis functional connectome: aberrant intrinsic networks in schizophrenia and bipolar disorder

Frontiers in Psychiatry, 2012
Intrinsic functional brain networks (INs) are regions showing temporal coherence with one another. These INs are present in the context of a task (as opposed to an undirected task such as rest), albeit modulated to a degree both spatially and temporally.

Macroeconomic Forecasting with Independent Component Analysis [PDF]

This paper considers a factor model in which independent component analysis (ICA) is employed to construct common factors out of a large number of macroeconomic time series. The ICA has been regarded as a better method to separate unobserved sources that

A Standardized Technique for Ultrasound–MRI Fusion Imaging of the Carotid Artery for Vascular Assessment

Journal of Ultrasound in Medicine, EarlyView.
Purpose To describe a reproducible ultrasound–magnetic resonance imaging (MRI) fusion imaging technique developed for quantitative assessment of carotid wall strain and plaque morphology. Methods MRI volumes (Oblique T2 Cube) were imported into the Sequoia ultrasound system equipped with an electromagnetic tracking module.

Terazosin Attenuates Neuronal Pyroptosis by Regulating the Mitochondrial ROS/NLRP3 Inflammasome Axis Through Mitophagy in Cerebral Ischemia–Reperfusion Injury

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Cerebral ischemia–reperfusion injury (CI/RI) is a major cause of secondary neuronal damage following ischemic stroke. This study investigated whether terazosin (TZ) exerts neuroprotective effects by regulating mitophagy and the reactive oxygen species (ROS)/NOD‐like receptor protein 3 (NLRP3) inflammasome axis.
