Although it is being successfully implemented for exploration of the genome, discovery science has eluded functional neuroimaging community. The core challenge remains development common paradigms interrogating myriad systems in brain without constraints a priori hypotheses. Resting-state MRI (R-fMRI) constitutes candidate approach capable addressing this challenge. Imaging during rest reveals large-amplitude spontaneous low-frequency (<0.1 Hz) fluctuations fMRI signal that are temporally...
Several brain areas show signal decreases during many different cognitive tasks in functional imaging studies, including the posterior cingulate cortex (PCC) and a medial frontal region incorporating portions of gyrus ventral anterior (MFG/vACC). It has been suggested that these are components default mode network is engaged rest disengaged tasks. This study investigated connectivity between PCC MFG/vACC working memory task at by examining temporal correlations magnetic resonance levels...
Abstract Functional connectivity among brain regions has been investigated via an analysis of correlations between regional signal fluctuations recorded in magnetic resonance (MR) images obtained a steady state. In comparison with studies functional that utilize task manipulations, the state data is less susceptible to confounds arising when functionally unrelated respond similar ways changes task. A new approach identifying interregional makes use two independent sets. Regions interest...
Does the speech motor control system use invariant vocal tract shape targets when producing vowels and semivowels? A 4-part theoretical treatment favoring models whose only are regions in auditory perceptual space over that posit constriction is presented. Auditory target hypothesized to arise during development as an emergent property of neural map formation system. Furthermore, movements planned trajectories space. These then mapped into articulator through a mapping allows equivalent...
Abstract Neurofeedback has begun to attract the attention and scrutiny of scientific medical mainstream. Here, neurofeedback researchers present a consensus-derived checklist that aims improve reporting experimental design standards in field.
Abstract Resting‐state functional magnetic resonance image (rs‐fMRI) is increasingly used to study brain networks. Nevertheless, variability in these networks due factors such as sex and aging not fully understood. This explored differences normal age trajectories of resting‐state (RSNs) using a novel voxel‐wise measure connectivity, the intrinsic connectivity distribution (ICD). Males females showed differential patterns changing large‐scale RSNs during from early adulthood late middle‐age....
Anxiety is a core human emotion but can become pathologically dysregulated. We used functional magnetic resonance imaging (fMRI) neurofeedback (NF) to noninvasively alter patterns of brain connectivity, as measured by resting-state fMRI, and reduce contamination anxiety. Activity region the orbitofrontal cortex associated with anxiety was in real time provided subjects significant subclinical NF signal, permitting them learn modulate target region. altered network connectivity regions...
Functional magnetic resonance imaging and repetitive transcranial stimulation (rTMS) were used to explore the pathophysiology of auditory/verbal hallucinations (AVHs). Sixteen patients with schizophrenia-spectrum disorder studied continuous or near AVHs. For intermittent (N = 8), blood oxygenation level–dependent (BOLD) activation maps comparing hallucination nonhallucination periods generated. 8) correlations between BOLD signal time course in Wernicke's area, other regions map functional...
The neural basis of human mental function is characterized by interactions between brain regions. Temporal correlations in MR signals areas may provide one method for investigating these interactions. This approach was used to examine functional connectivity the motion processing system brain. Correlations MT/V5 and other regions were examined a resting state (without visual stimulation) an active produced viewing moving concentric circles. A network consistent with known anatomy correlated...
Background Neuroimaging studies have revealed that disturbances in network organization of key brain regions may underlie cognitive and emotional dysfunction posttraumatic stress disorder (PTSD). Examining both structure function the same population further our understanding alterations PTSD. Methods We used tensor-based morphometry intrinsic connectivity distribution to identify altered volume functional unmedicated individuals with PTSD ( n = 21) healthy comparison participants 18). These...
