Background Graph theory and machine learning have been shown to be effective ways of classifying different stages Alzheimer’s disease (AD). Most previous studies only focused on inter-subject classification with single-mode neuroimaging data. However, whether this can truly reflect the changes in structure function brain region progression remains unverified. In current study, we aimed evaluate framework, which combines structural Magnetic Resonance Imaging (sMRI) resting-state functional...

Abstract The ability to perceive, understand, and react the feelings of others' pain is referred as empathy for which composed two components, affective‐perceptual cognitive‐evaluative empathy. Recent reviews on neural mechanisms empathetic showed anterior insula (AI) cortex a core circuit However, little known about modulation brain anatomy empathic responses by trait measures (trait empathy). Thus, we investigated whether individual variation in personality associated with structure...

Recent studies have suggested that the right inferior frontal gyrus (rIFG) may be involved in pain-related empathy. To verify role of rIFG, we performed a functional magnetic resonance imaging (fMRI) experiment to replicate previous research and further designed noninvasive repetitive transcranial stimulation (rTMS) probe causal rIFG empathy processing. We assigned 74 volunteers (37 females) three groups. Group 1 (n = 26) task which participants were required perceive pain others (task pain:...

Obsessive-compulsive disorder (OCD) is a common neuropsychiatric characterized by intrusive thoughts (obsessions) and repetitive behaviors (compulsions), few studies have assessed the whole-brain functional connectivity architecture of OCD with electroencephalogram (EEG) during different resting states. Graph theory network-based statistics (NBS) were employed to examine neural synchronization (FC) based on phase-locking value (PLV) patients healthy controls (HCs) eyes-closed (EC) eyes-open...

The contents of working memory (WM) can affect the subsequent visual search performance, resulting in either beneficial or cost effects, when target is included spatially dissociated from memorized contents, respectively. right dorsolateral prefrontal cortex (rDLPFC) and posterior parietal (rPPC) have been suggested to be associated with congruence/incongruence effects content target. Thus, present study, we investigated role DLPFC PPC controlling interaction between WM attention during a...

Working memory (WM) training is a prevalent intervention for multiple cognitive deficits, however, the transfer effects to other tasks from gains in WM induced by different techniques still remains controversial. Therefore, current study recruited three groups of young adults investigate transference, with N-back group (NBG) (n = 50) on dual n-back task, Memory Palace (MPG) method loci, and blank control (BCG) 48) receiving no training. Our results showed that both separately improved...

The experience in virtual reality (VR) is unique, that observers are a real-world location while browsing through scene. Previous studies have investigated the effect of environment on distance estimation. However, it unclear how influences estimation VR. Here, we measured using bisection (Experiment 1) and blind-walking (Experiments 2 3) method. Participants performed judgments VR, which rendered either indoor or outdoor scenes. Experiments were also carried out locations. In experiment,...
