The origin of auditory hallucinations, which are one the core symptoms schizophrenia, is still a matter debate. It has been hypothesized that alterations in connectivity between frontal and parietotemporal speech-related areas might contribute to pathogenesis hallucinations. These networks assumed become dysfunctional during generation monitoring inner speech. Magnetic resonance diffusion tensor imaging relatively new vivo method investigate directionality cortical white tracts.To...
We present a program (Ragu; Randomization Graphical User interface) for statistical analyses of multichannel event-related EEG and MEG experiments. Based on measures scalp field differences including all sensors, using powerful, assumption-free randomization statistics, the yields robust, physiologically meaningful conclusions based entire, untransformed, unbiased set measurements. Ragu accommodates up to two within-subject factors one between-subject factor with multiple levels each....
Abstract BACKGROUND Epi proColon® is a new blood-based colorectal cancer (CRC) screening test designed to determine the methylation status of promoter region SEPT9 (septin 9) gene in cell-free DNA isolated from plasma. We describe analytical and clinical performance test. METHODS Analytical at 4 testing laboratories included determination limit detection, precision, reproducibility Clinical was evaluated prospective study by use samples (n = 1544) subjects enrolled PRESEPT trial. Results...
We review the theory and algorithms of electrophysiological brain connectivity analysis. This tutorial is aimed at providing an introduction to functional from signals, including electroencephalography, magnetoencephalography, electrocorticography, stereoelectroencephalography. Various estimators are discussed, introduced. Important issues for estimating mapping with electrophysiology discussed.
Semiconductor detector readout chips with pulse processing electronics have made possible spectroscopic X-ray imaging, bringing an improvement in the overall image quality and, case of medical a reduction dose delivered to patient. In this contribution we review state art semiconductor-detector ASICs for imaging emphasis on hybrid pixel technology. We discuss how some key challenges technology (such as dealing high fluxes, maintaining spectral fidelity, power consumption density) are...
Protein identification by tandem mass spectrometry is based on the reliable processing of acquired data. Unfortunately, generation a large number poor quality spectra commonly observed in LC-MS/MS, and these mostly noninformative with its associated costs should be avoided. We present continuous score that can computed very quickly considered an approximation MASCOT case correct identification. This used to reject low prior database identification, or draw attention those exhibit...
Background fMRI Resting State Networks (RSNs) have gained importance in the present literature. Although their functional role is unquestioned and physiological origin nowadays widely accepted, little known about relationship to neuronal activity. The combined recording of EEG allows temporal correlation between fluctuations RSNs dynamics spectral amplitudes. So far, only relationships several frequency bands some could be demonstrated, but no study accounted for spatial distribution domain...
Schizophrenia patients show abnormalities in a broad range of task demands. Therefore, an explanation common to all these has be sought independently any particular task, ideally the brain dynamics before takes place or during resting state. For neurobiological investigation such baseline states, EEG microstate analysis is particularly well suited, because it identifies subsecond global states stable connectivity patterns directly related recruitment different types information processing...
Synaptic dysfunction is the best anatomical correlate of early cognitive impairment in Alzheimer's disease (AD). Electroencephalography (EEG) directly reflects brain electrical activity at level synapses. The aim present study was to investigate correlations quantitative EEG measures, global field power (GFP) and synchronization (GFS), with conventional cerebrospinal fluid (CSF) biomarkers neurodegeneration patients diagnosed subjective decline (n = 210), mild 230), AD 197). Decreased CSF...
