While conservatism bias refers to the human need for more evidence for decision‐making than rational thinking expects, the jumping to conclusions (JTC) bias refers to the need for less evidence among individuals with schizophrenia/delusion compared to healthy people. Although the hippocampus‐midbrain‐striatal aberrant salience system and the salience, default mode (DMN), and frontoparietal...

We examined the neural underpinnings of the effects of mindfulness on anxiety in anorexia nervosa using functional magnetic resonance imaging in 21 anorexia patients. We used a functional magnetic resonance imaging task designed to induce weight-related anxiety and asked participants to regulate their anxiety either using or not using an acceptance strategy. Our results showed reduced activity...

Experienced Qigong meditators who regularly perform the exercises "Thinking of Nothing" and "Qigong" were studied with multichannel EEG source imaging during their meditations. The intracerebral localization of brain electric activity during the two meditation conditions was compared using sLORETA functional EEG tomography. Differences between conditions were assessed using t statistics...

IntroductionDifferent meditation practices reportedly affect brain electric activity.ObjectivesTo assess common characteristics in brain electric activity during the state of meditation across different meditation traditions.AimsDo meditation traditions share commonalities in EEG spectral power changes from task-free resting to meditation?MethodsData from 71 experienced meditators of five...

IntroductionThe measure of complex dimensionality assesses the number of independent processes that generate an observed time series.ObjectivesTo investigate whether meditation exercises are associated with fewer or more independently active brain processes, and whether different meditation traditions show different results.AimsDoes brain electric complex dimensionality differ between the state...

Many meditation exercises aim at increased awareness of ongoing experiences through sustained attention and at detachment, i.e., non-engaging observation of these ongoing experiences by the intent not to analyze, judge or expect anything. Long-term meditation practice is believed to generalize the ability of increased awareness and greater detachment into everyday life. We hypothesized that...

Abstract: Neural activity is known to oscillate within discrete frequency bands and the synchronization between these rhythms is hypothesized to underlie information integration in the brain. Since strict synchronization is only possible for harmonic frequencies, a recent theory proposes that the interaction between different brain rhythms is facilitated by transient harmonic frequency...

Abstract: Background and hypothesis: While the conservatism bias refers to the human need for more evidence for decision-making than rational thinking expects, people with schizophrenia and delusion require less evidence, known as the jumping to conclusions (JTC) bias. The midbrain-striatal aberrant salience of schizophrenia is postulated to form delusion; however, the association between...
