Introduction: Repetitive negative thinking (RNT) is a cognitive process focusing on self-relevant and experiences, leading to poor prognosis of major depressive disorder (MDD). We previously identified that connectivity between the precuneus/posterior cingulate cortex (PCC) right temporoparietal junction (rTPJ) was positively correlated with levels RNT. Objective: In this double-blind, randomized, sham-controlled, proof-of-concept trial, we employed real-time functional magnetic resonance...
Background:We have obtained previous evidence of limbic dysfunction in middle-aged, asymptomatic offspring late-onset Alzheimer's disease (LOAD) patients, and failure to recover from proactive semantic interference has been shown be a sensitive cognitive test other groups at risk for LOAD. Objective:To assess the effects specific deficits as they relate functional magnetic resonance imaging (fMRI) neocortical connectivity middle aged individuals with LOAD (O-LOAD) age-equivalent controls....
Increasing evidence suggests that responsiveness is associated with critical or near-critical cortical dynamics, which exhibit scale-free cascades of spatio-temporal activity. These cascades, 'avalanches', have been detected at multiple scales, from in vitro and vivo microcircuits to voltage imaging brain-wide functional magnetic resonance (fMRI) recordings. Criticality endows the cortex certain information-processing capacities postulated as necessary for conscious wakefulness, yet it...
Abstract Background Repetitive negative thinking (RNT), a cognitive process that encompasses past (rumination) and future (worry) directed thoughts focusing on experiences the self, is transdiagnostic construct especially relevant for major depressive disorder (MDD). Severe RNT often occurs in individuals with severe levels of MDD, which makes it challenging to disambiguate neural circuitry underlying from depression severity. Methods We used propensity score, i.e., conditional probability...
Individual differences in the ability to process language have long been discussed. Much of neural basis these, however, is yet unknown. Here we investigated relationship between long-range white matter connectivity brain, as revealed by diffusion tractography, and syntactically complex sentences participants' native well improvement thereof multiday training. We identified specific network motifs singular value decomposition that indeed related structural individual processing performance....
Failure to recover from proactive semantic interference (frPSI) has been shown be more sensitive than traditional cognitive measures in different populations with preclinical Alzheimer's disease. The authors sought characterize the structural and amyloid vivo correlates of frPSI cognitively normal offspring patients late-onset disease (O-LOAD), compared individuals without a family history neurodegenerative disorders (CS). evaluated LASSI-L, test tapping other types delayed recall on RAVLT,...
A large proportion of acute respiratory tract infections (ARTI) remain without etiologic diagnosis, reason why new pathogens are investigated continuously. Human bocavirus (HBoV) was discovered in 2005, as a member Parvoviridae family and proposed to cause ARTI.To know the prevalence HBoV among pediatric populations hospitalized for ARTI two provinces Argentina: Santa Fe Tucuman; describe epidemiological clinical aspects associated its detection.We studied nasopharyn-geal aspirates patients...
It is commonly accepted that in most patients with schizophrenia external factors act on genetic predisposition to produce active psychotic symptoms. In fact, we showed have an abnormal brain activation and peripheral autonomic response psychological stress. We sought characterize the connectivity networks of such schizophrenia. studied pattern relation mental arithmetic stress paradigm 21 healthy subjects aged 18 50 years, using 3T-fMRI. A period 6 minutes resting state acquisition (PRE)...
Abstract Individual differences in the ability to deal with language have long been discussed. The neural basis of these, however, is yet unknown. Here we investigated relationship between long-range white matter connectivity brain, as revealed by diffusion tractography, and process syntactically complex sentences participants’ native well improvement thereof multi-day training. We identified specific network motifs that indeed related tractography individual processing performance. First,...
Abstract Background Depression (MDD) is associated with an unusually large amount of individual disability and societal costs as well unsatisfactory outcomes well-established therapies, including psychotropic drugs different types psychotherapy. Based on increasing interest in modulation brain circuits involved specific symptoms depression, we chose to target a single measurable replicable construct repetitive negative thinking (RNT), transdiagnostic clinical manifestation that cuts across...
