Background and Purpose— Many ischemic strokes or transient attacks are labeled cryptogenic but may have undetected atrial fibrillation (AF). We sought to identify those most likely subclinical AF. Methods— prospectively studied patients with stroke attack aged ≥55 years in sinus rhythm, without known AF, enrolled the intervention arm of 30 Day Event Monitoring Belt for Recording Atrial Fibrillation After a Cerebral Ischemic (EMBRACE) trial. Participants underwent baseline 24-hour Holter ECG...
Adult attention-deficit/hyperactivity disorder (ADHD) is a serious and frequent psychiatric of multifactorial pathogenesis. Several lines evidence support the idea that ADHD is, in its core, dysfunctional brain connectivity within between several neurofunctional networks. The primary aim this study was to investigate associations functional resting state networks individual severity core symptoms (inattention, hyperactivity, impulsivity). Resting magnetic resonance imaging (rs-fMRI) data 38...
FUNCTIONAL magnetic resonance imaging (fMRI) and magnetoencephalography (MEG) were performed in six subjects during self-paced finger movement performance, tactile somatosensory stimulation binaural auditory using identical paradigms. Both functional modalities localized brain activity adjacent areas of anatomically correct cortex. The mean distances measured between fMRI the corresponding MEG dipoles 10.1 mm (motor), 10.7 (somatosensory), 13.5 (auditory right hemisphere) 14.3 left...
Focal lesions of the frontal, parietal and temporal lobe may interfere with tactile working memory attention. To characterise neural correlates intact vibrotactile attention, functional MRI was conducted in 12 healthy young adults. Participants performed a forced-choice frequency discrimination task, comparing cue stimulus fixed to their right thumb probe identical or higher frequency. investigate memory, time interval between 2 stimuli pseudo-randomized (either 8 s). selective distractor...
Impaired speech perception is one of the major sequelae aging. In addition to peripheral hearing loss, central deficits auditory processing are supposed contribute deterioration in older individuals. To test hypothesis that temporal compromised aging, evoked magnetic fields were recorded during stimulation with sequences 4 rapidly recurring sounds 28 healthy individuals aged 20 - 78 years.The decrement N1m amplitude rapid was not significantly different between and younger adults. The...
Introduction Aging influences the morphology of central nervous system. While several previous studies focused on morphometric changes supratentorial parts, investigations age-related cerebellar are rare. The literature concerning morphological in cerebellum is heterogenous depending (i) methods used (cerebellar analysis context a whole brain or specific for analysis), (ii) life span that was investigated, and (iii) analytic approach (i.e., using linear non-linear methods). Methods We fill...
This study presents data on the clinical characteristics and possible mechanisms of phantom eye syndrome in 112 patients after removal one eye. The prevalence pain was 26%, nonpainful sensations 29%, visual hallucinations 31%. Headaches preoperative were associated with presence experiences. These results suggest that is an important cofactor for development phenomena.
Abstract To identify robust and reproducible methods of cerebellar morphometry that can be used in future large-scale structural MRI studies, we investigated the replicability, repeatability, long-term reproducibility three fully automated software tools: FreeSurfer, CEREbellum Segmentation (CERES), automatic cerebellum anatomical parcellation using U-Net with locally constrained optimization (ACAPULCO). Replicability was defined as computational determined by comparing two analyses same...
Abstract Chronic pain is often associated with changes in brain structure and function, also cognitive deficits. It has been noted that these chronic pain-related alterations may resemble found healthy aging, thus represent accelerated or premature aging of the brain. Here, we test hypothesis patients noncancer demonstrate compared control subjects. The predicted age 59 (mean chronological ± SD: 53.0 9.0 years; 43 women) 60 pain-free controls (52.6 44 was determined using software brainageR...
