To investigate the impact of chronic pain on brain dynamics at rest.Functional connectivity was examined in patients with fibromyalgia (FM) (n = 9) and healthy controls 11) by calculating partial correlations between low-frequency blood oxygen level-dependent fluctuations extracted from 15 regions.Patients FM had more positive negative within network than controls. Patients displayed enhanced functional anterior cingulate cortex (ACC) insula (INS) basal ganglia (p values .01 .05), secondary...

Alzheimer's disease (AD) is the most common age-related neurodegenerative disorder. In view of our rapidly aging population, there an urgent need to identify at early stage. A potential way do so by assessing functional connectivity (FC), i.e., statistical dependency between two or more brain regions, through novel analysis techniques.In present study, we assessed static and dynamic FC using different approaches. resting state (rs)fMRI dataset from neuroimaging initiative (ADNI) was used (n...

Despite considerable research on experience-dependent neuroplasticity in professional musicians, detailed understanding of an involvement the insula is only now beginning to emerge. We investigated effects musical training intrinsic insula-based connectivity classical musicians relative nonmusicians using resting-state functional MRI. Following a tripartite scheme subdivisions, coactivation profiles were analyzed for posterior, ventral anterior, and dorsal anterior both hemispheres. While...

Previous fMRI findings have shown that chronic pain patients display an altered activation and functional connectivity of the network. The aim present study was to analyze EEG dynamics in fibromyalgia (n = 20) pain-free controls 18) at rest.Spectral power density, source current intra- inter-hemispheric coherence were analyzed from 64 channels during 5-minutes eyes-closed rest.Results indicated displayed reduced density delta band (2-4 Hz) over right insula, superior middle temporal gyri as...

Understanding and classifying brain states as a function of sleep quality age has important implications for developing lifestyle-based interventions involving hygiene. Current studies use an algorithm that captures non-linear features complexity to differentiate awake electroencephalography (EEG) states, quality. Fifty-eight participants were assessed using the Pittsburgh Sleep Quality Inventory (PSQI) resting state EEG. Groups formed based on (younger adults n = 24, mean 24.7 years, SD...

Objective. Pain is a serious problem for many individuals with cerebral palsy (CP). and injury in early life may cause long-term changes somatosensory pain processing. Nevertheless, no information exists regarding the influence of age on reports touch sensitivity among persons CP or quality CP. Design. The present cross-sectional study investigated characteristics, sensitivity, 86 115 healthy volunteers. Participants were grouped by children (6–10 years), adolescents (11–17 young adults...

Recent work on functional magnetic resonance imaging large-scale brain networks under resting conditions demonstrated its potential to evaluate the integrity of function normal and pathological conditions. A similar approach is used in this study a group chronic back pain patients healthy controls determine impact long enduring over dynamics. Correlation were constructed from mutual partial correlations activity's time series selected ninety regions using well validated parcellation atlas....

Chronic pain is known as a complex disease due to its comorbidities with other symptoms and the lack of effective treatments. As consequence, chronic seems be under-diagnosed in more than 75% patients. At same time, advance brain imaging, popularization machine learning techniques development new diagnostic tools based on these technologies have shown that could an option supporting decision-making healthcare professionals. In this study, we computed functional connectivity using...

We present a novel method, Fractal Space-Curve Analysis (FSCA), which combines Space-Filling Curve (SFC) mapping for dimensionality reduction with fractal Detrended Fluctuation (DFA). The method is suitable multidimensional geometrically embedded data, especially neuroimaging data highly correlated temporally and spatially. conduct extensive feasibility studies on diverse, artificially generated known characteristics: the fractional Brownian motion, Cantor sets, Gaussian processes. compare...

Facial expression is one of the most relevant nonverbal behaviors in communication pain. However, little known about brain processing pain expressions comparison with other affective facial expressions. The present experiment aimed to examine effects intensity on ratings and dynamics by recording electroencephalography (EEG) from 20 female healthy volunteers 18-24 years age. Participants were asked rate characteristics 144 stimuli depicting anger 3 level intensities (high, mild, low), as...

Signals from brain functional magnetic resonance imaging (fMRI) can be efficiently represented by a sparse spatiotemporal point process, according to recently introduced heuristic signal processing scheme. This approach has already been validated for relevant conditions, demonstrating that it preserves and compresses surprisingly large fraction of the information. Here we investigated conditions necessary such an succeed, as well underlying reasons, using real fMRI data simulated dataset....

Abstract Introduction In clinical consultations, men with erectile dysfunction do not always express personal, sexual, and interpersonal concerns. Aim We explore whether the attenuated impact of may be explained by a regulation negative affect that causes activation attachment system. Methods The study sample consisted 69 diagnosed dysfunction, mean (SD) age 56 (10.83) years. Participants completed self-reported questionnaires to assess severity, style, sexual satisfaction, relationship...

Abstract Background Although cerebral palsy (CP) is usually defined as a group of permanent motor disorders due to non-progressive disturbances in the developing fetal or infant brain, recent research has shown that CP individuals are also characterized by altered somatosensory perception, increased pain and abnormal activation cortical areas. The present study was aimed examine hemispheric differences on brain processing with bilateral lateralized impairments compared healthy controls. Nine...

The objective of this study was to examine the benefits Snoezelen room for older people living in nursing homes. Participants were 84 with dementia from Barcelona (Spain) that randomly assigned or reminiscence sessions. Bi-weekly sessions held over a period 12 weeks. group displayed significant improvements depression and anxiety greater degree relaxation. slight also more likely display alertness offer constructive answers. could be implemented range dementia's stages, stressing its...

The center stage of neuro-imaging is currently occupied by studies functional correlations between brain regions. These define the networks, which are most frequently used framework to represent and interpret a variety experimental findings. In previous work we first demonstrated that relatively stronger BOLD activations contain information relevant understand connectivity subsequent confirmed large compression original signals can be obtained without significant loss information. this...

In this research, the relationship between attachment and psychopathology was studied in a sample of 40 adolescents young adults who have suffered from intrafamily maltreatment. Attachment assessed with Bartholomew's RQ, which distinguishes four styles depending on positive or negative image self others: secure, preoccupied, fearful dismissive attachment. Results show that insecure attachment, particularly subtype, is most prevalent one. Slightly more than half (52.5%) shows clinically...

Neurofeedback is a form of neuromodulation based on learning to modify some aspects cortical activity. Sensorimotor rhythm (SMR) oscillation one the most used frequency bands in neurofeedback. Several studies have shown that subjects can learn modulate SMR power control output devices, but little known about possible related changes brain networks. The aim this study was investigate enhanced performance and EEG spectral density at somatosensory cerebral areas due bidirectional...
