Abstract Transcranial magnetic stimulation (TMS)–evoked electroencephalography (EEG) potentials (TEPs) provide unique insights into cortical excitability and connectivity.

Background Having social support improves one's health outcomes and self-esteem, buffers the negative impact of stressors. Previous studies have explored association between brain activity, but evidence from task-dependent functional connectivity is still limited. Aims We aimed to explore how gradually decreasing levels influence across several major neural networks. Method designed a task recruited 72 young adults real-life groups. Of four members in each group, one healthy participant (18 participants total) completed magnetic resonance imaging (fMRI) scan. The fMRI included three phases with varying support: high-support phase, fair phase low-support phase. Functional changes according were examined by generalised psychophysiological interaction analysis. Results results analysis demonstrated that losing expected showed increased among salience network, default mood network frontoparietal nodes during compared During only Conclusions indicate loss was perceived as threat signal induced widespread within observation significant suggests even small close ones leads function.

Abstract INTRODUCTION Subjective cognitive decline (SCD) is linked to memory complaints and disruptions in certain brain regions identified by molecular imaging resting‐state functional magnetic resonance studies. However, it remains unclear how these interact contribute both subjective potential objective issues SCD. METHODS To address this gap, task‐based studies are essential. The Mnemonic Similarity Task assessed high‐fidelity retrieval meanwhile MRI data measured group differences activation connectivity (FC) (calculated generalized psychophysiological Interaction) between SCD individuals normal controls. RESULTS Worse was associated with hypoactivation the hippocampus, hyperactivation control network (CN), reduced FC hippocampus CN. angular gyrus (AG) partially drives disconnection. DISCUSSION This study confirms deficits highlights AG's failure integrate, addressing a gap literature that has primarily focused on Highlights Objective detected older adults Dysfunctional neural activations within networks impair accuracy. Reduced deficits. SCD‐related disruption of integrative function partly explains such Future may benefit from inspections obstruction process.

This review provides an overview of the most prominent neurocognitive effects cognitive bias modification (CBM), cue-exposure therapy and mindfulness interventions for targeting addictive responses. It highlights key insights that have stemmed from neuroscience brain imaging research combines these with behavioural science in building a conceptual model integrating response-focused CBM or interventions. furthers our understanding whether how strategies may i) facilitate add to induced decreasing cue-induced craving, ii) further weaken link between craving Specifically, awareness/monitoring facilitate, decentering to, effects. Combined awareness acceptance also diminish craving-addiction link. The presented this specific theoretical framework deepen can be combined greatest effect. is important both suggesting roadmap future research, development clinical
