Abstract In recent years, brain research has indisputably entered a new epoch, driven by substantial methodological advances and digitally enabled data integration modelling at multiple scales—from molecules to the whole brain. Major are emerging intersection of neuroscience with technology computing. This science combines high-quality research, across scales, culture multidisciplinary large-scale collaboration, translation into applications. As pioneered in Europe’s Human Brain Project...
Optometrists, ophthalmologists, orthoptists, and other trained medical professionals use fundus photography to monitor the progression of certain eye conditions or diseases. Segmentation vessel tree is an essential process retinal analysis. In this paper, interactive blood segmentation from image based on Canny edge detection proposed. Semi-automated specific vessels can be done by simply moving cursor across a particular vessel. The pre-processing stage includes green color channel...
This paper extends frequency domain quantitative electroencephalography (qEEG) methods pursuing higher sensitivity to detect Brain Developmental Disorders. Prior qEEG work lacked integration of cross-spectral information omitting important functional connectivity descriptors. Lack geographical diversity precluded accounting for site-specific variance, increasing nuisance variance. We ameliorate these weaknesses. (i) Create lifespan Riemannian multinational norms tensors. These result from...
Research suggests that white noise may facilitate auditory working memory performance via stochastic resonance. Stochastic resonance is quantified by plotting cognitive as a function of intensity. The plot would appear an inverted U-curve, is, moderate beneficial for whereas too low and much attenuates performance. However, knowledge about the optimal signal-to-noise ratio (SNR) needed to occur in brain, particularly neural network memory, limited demand further investigation. In present...
Traumatic brain injury (TBI) is one of the injuries that can bring serious consequences if medical attention has been delayed. Commonly, analysis computed tomography (CT) or magnetic resonance imaging (MRI) required to determine severity a moderate TBI patient. However, due rising number patients these days, employing CT scan MRI every potential patient not only expensive, but also time consuming. Therefore, in this paper, we investigate possibility using electroencephalography (EEG) with...
The debilitating effect of traumatic brain injury (TBI) extends years after the initial and hampers recovery process quality life. In this study, we explore functional reorganization default mode network (DMN) those affected with non-severe TBI. Traumatic is a wide-spectrum disease that has heterogeneous effects on its victims impacts everyday functioning. disruption TBI been established, but link to causal effective connectivity remains be explored. This study investigated differences in...
The Helicobacter pylori infection rate was determined in 124 consecutive patients with duodenal ulcers (DU), gastric (GU), erosions or diagnosed by endoscopy at a single institution north-eastern peninsular Malaysia 1996–1997. Biopsies of the antrum and body were subjected to urease test, Gram staining impression smears, culture histopathological examination. Serology undertaken on all using locally validated commercial kit. Infection defined as positive result least one test. rates 20%...
Background The auditory and prefrontal cortex supports working memory processing. Many neuroimaging studies have shown hemispheric lateralization of brain regions in the presence background noise, but few focused on these during stochastic resonance. Purpose To investigate effects resonance regions, also to examine brain‐behavior relationship Study Type Cross‐sectional. Population/Subjects Forty healthy young adults (18–24 years old). Field Strength/Sequence 3.0T, T 1 , 2 *‐weighted imaging....
Traumatic brain injury (TBI) is one of the common injuries when human head receives an impact due to accident or fall and most frequently submitted insurance claims. However, it often always misused individuals attempt fraud claim by providing false medical conditions. Therefore, there a need for instant condition classification system. This study presents novel architecture that can classify non-severe TBI patients healthy subjects employing resting-state electroencephalogram (EEG) as...
fMRI-based retinotopic mapping was used to assess systematic variations in activated cortical surface area, amplitude, and coherence across sessions. Seven healthy subjects were scanned at 7 T three separate sessions with intervals of 51.4 ± 5.4 days (Session 1 Session 2) 167.9 24.4 2 3). We found a reduction between Sessions for 3 2/3 coherence. The results do not support head motion as major cause the observed effect seen 1, suggesting that cognitive effects underlying change. phase...
Impairment in cognitive function is a recognized outcome of traumatic brain injury (TBI). However, the degree impairment has variable relationship with TBI severity and time post injury. The underlying pathology often due to diffuse axonal that been found even mild TBI. In this study, we examine state white matter putative connectivity patients non-severe subacute phase, i.e., within 10 weeks determine its neuropsychological scores.We conducted case-control prospective study involving 11...
Abstract This fMRI study investigated the effects of vibratory stimulation on somatosensory areas during high-frequencies using a piezoelectric finger system an scan. Twelve healthy right-handed subjects were stimulated at 270 Hz-480 Hz and dataset was analysed to generate activated regions due stimulation. The identified thresholded Puncorrected<0.001 for multiple comparisons. average effect frequencies revealed significant activation in left thalamus, right inferior parietal gyrus,...
Abstract The relationship between resting effective connectivity (EC) among default mode network (DMN) regions and auditory working memory (AWM) performance is still poorly understood. In this work, resting-state functional magnetic resonance imaging (rsfMRI) was used to determine the optimum model posterior cingulate cortex (PCC) medial prefrontal (mPFC) in 40 healthy male volunteers. low normal groups of subjects. Correlation EC with AWM AWM-capacity also studied. participants were divided...
This study investigated the functional connectivity of neural networks when vibrotactile stimulation is applied to fingertips young adults. Twenty healthy, right-handed subjects were stimulated with whilst being scanned a 3.0 T magnetic resonance imaging scanner. The at 30 Hz – 240 using piezoelectric vibrator attached subjects' bilateral index fingers. data processed independent component analysis (ICA), while temporal configuration and spatial localisation investigated. activation...
