Music reduces pain in fibromyalgia (FM), a chronic disease, but the functional neural correlates of music-induced analgesia are still largely unknown. We recruited FM patients (n = 22) who listened to their preferred relaxing music and an auditory control (pink noise) for 5 minutes without external noise from fMRI image acquisition. Resting state was then acquired before after conditions. A significant increase amplitude low frequency fluctuations BOLD signal evident left angular gyrus...
Abstract While brain default mode network (DMN) activation in human subjects has been associated with mind wandering, meditation practice found to suppress it and increase psychological well-being. In addition DMN activity reduction, experienced meditators (EMs) during show an increased connectivity between the central executive (CEN). However, gradual change CEN configuration from pre-meditation, meditation, post-meditation is unknown. Here, we investigated by means of functional (FC)...
Heating of gradient coils and passive shim components is a common cause instability in the B0 field, especially when intensive sequences are used. The aim study was to set benchmark for typical drift encountered during MR spectroscopy (MRS) assess need real-time field-frequency locking on MRI scanners by comparing field data from large number sites. A standardized protocol developed 80 participating sites using 99 3T 3 major vendors. Phantom water signals were acquired before after an EPI...
Temporal lobe epilepsy (TLE) is a common form of medically intractable epilepsy. Although seizures originate in mesial temporal structures, there are widespread abnormalities gray and white matter beyond the lobes that negatively impact functional networks cognition. Previous studies have focused either on global networks, or correlates specific cognitive abilities. Here, we use two-pronged approach to evaluate link between whole-brain connectivity (FC) anomalies overall performance, how...
Background: Gesture Therapy is an upper limb virtual reality rehabilitation-based therapy for stroke survivors. It promotes motor rehabilitation by challenging patients with simple computer games representative of daily activities self-support. This has demonstrated clinical value, but the underlying functional neural reorganization changes associated this that are responsible behavioral improvements not yet known. Objective: We sought to quantify occurrence strategies underlie as they occur...
Abstract Purpose T 1 mapping is a widely used quantitative MRI technique, but its tissue‐specific values remain inconsistent across protocols, sites, and vendors. The ISMRM Reproducible Research Quantitative MR study groups jointly launched challenge to assess the reproducibility of well‐established inversion‐recovery using acquisition details from seminal paper on standardized phantom in human brains. Methods protocol Barral et al. (2010). Researchers collected data ISMRM/NIST and/or Data...
Up until now, neural mechanisms associated with psychological restoration process related to brain activity have not been identified. We explored the correlates of restorative environment exposure functional magnetic resonance imaging while participants viewed photographs low or high potential (LRP and HRP, respectively). Baseline measurements self-reported stress before viewing these two categories environments post-test were considered as behavioural evidence restoration. Activation middle...
Abstract Listening to self-chosen, pleasant and relaxing music reduces pain in fibromyalgia (FM), a chronic centralized condition. However, the neural correlates of this effect are fairly unknown. In our study, we wished investigate music-induced analgesia (MIA) FM patients. To do this, studied 20 patients matched healthy controls (HC) acquiring rs-fMRI with 3T MRI scanner, data before after two 5-min auditory conditions: noise. We performed resting state functional connectivity (rs-FC)...
Phantom limb (PL), a phenomenon experienced by most patients after amputation, has mostly served as paradigm to study experiences that appear be associated with neural plasticity within the CNS. However, subjective nature of PL had no definitive means reliable assessment other than using patients' direct reports, nor was there way mechanisms involved in conscious awareness this mental phenomenon. Here we obtained indirect responses for an objective evaluation functional magnetic resonance...

The phantom limb phenomenon has been used in amputee patients as a paradigm to study plasticity, mainly of the sensorimotor cortex. Nevertheless, most functional studies have done upper using magnetoencephalography and magnetic resonance image imaging (fMRI). In addition, actual experience sensation not widely neural mechanism human brain conscious knowledge perception like integration body patients. fMRI with lower amputation recently published, but none these an event-related design try...
Mentalizing is a fundamental aspect of social cognition that includes understanding the mental states others. This process involves participation well-defined set brain regions. However, it still unknown how different contextual situations, such as previous cooperative or non-cooperative interactions, can modulate activity related to inference others' states. Hence, this study investigated whether interaction neural mechanisms involved in way response inferred cooperators and non-cooperators...
Abstract Reading learning disability (RLD) is characterized by a specific difficulty in to read that not better explained an intellectual disability, lack of instruction, psychosocial adversity, or neurological disorder. According the domain-general hypothesis, working memory deficit primary problem. Working this population has recently been linked altered resting-state functional connectivity within default mode network (DMN), salience (SN), and frontoparietal (FPN) compared typically...
Excess theta electroencephalographic (EEG) activity has been described as an accurate predictor for cognitive decline at least 7 years before symptom presentation. To test whether this correlates with structural changes in the brains of healthy elderly individuals, we compared magnetic resonance images individuals excess [group a risk decline, group (RG); n=14] controls normal EEG (control group; n=14). Neuropsychological and epidemiological analyses showed significant differences only two...
Religiosity influences the alleviation of troubles through cooperative and empathic attitudes, but these involve a sense community offered in non-religious support groups healthcare institutions too, where individual’s spiritual wellbeing is based on responsibility solidarity. This case Alcoholic Anonymous program adopted by several care initiatives, which use Franciscan Prayer as fundamental text representing western epistemic meaning-making system to provide guidance for cooperation...
The increase of violence in Mexico and consequent suffering during the last decades is evident, but its effects over feelings moral judgments remain uncertain. We used journalistic news showing real-life situations to investigate facing experience four emotions which represent powerful impulses for social actions linked violence: Negative Compassion, Positive Schadenfreude, Indignation. evaluate brain activation by using functional magnetic resonance imaging (fMRI) three cognitive...
Visuospatial working memory refers to the short-term storage and manipulation of visuospatial information. To study neural bases these processes, 17 participants took part in a modified sequential Vernier task while they were being scanned using an event-related functional MRI protocol. During each trial, retained spatial position line during delay period later evaluate if it was presented aligned second line. This design allowed testing information from memory. encoding, there larger...
Different theoretical models have proposed cognitive and affective components in empathy moral judgments encompassing compassion. Furthermore, gender differences psychological neural functions involving empathic processing, as well compassionate experiences, been reported. However, the neurobiological function regarding integration underlying compassion gender-associated has not investigated. In this study, we aimed to examine interaction between emotional through functional connectivity...
Identifying faces is a process central for social interaction and relevant factor in eyewitness theory. False recognition critical mistake during an eyewitness's identification scenario because it can lead to wrongful conviction. Previous studies have described neural areas related false facial using the standard Deese/Roediger-McDermott (DRM) paradigm, triggering recognition. Nonetheless, misidentification of without trying elicit memories (unrelated recognition) police lineup could involve...
