Major Depressive Disorder (MDD) poses a significant public health challenge due to its high prevalence and the substantial burden it places on individuals and healthcare systems. Real-time functional magnetic resonance imaging neurofeedback (rtfMRI-NF) shows promise as a treatment for this disorder, although its mechanisms of action remain unclear. This study investigated whole-brain response patterns during rtfMRI-NF training to explain interindividual variability in clinical efficacy in MDD.

Background: Although lenvatinib is effective for unresectable thyroid carcinoma, it may cause adverse events owing to rapid tumor shrinkage or necrosis. Pneumothorax during lenvatinib therapy is rare. However, once it occurs, it can become a refractory and fatal complication.

Background: Mindfulness training has been shown to promote positive mental health outcomes and related changes in neural networks such as the default mode network, which has a central node in the posterior cingulate cortex (PCC). Previous work from our group reported on the impact of a novel, neurofeedback augmented mindfulness training (NAMT) task on regulation of PCC hemodynamic activity in typically developing adolescents. The present pilot study aimed to expand on this finding by examining the pre-post changes of the NAMT task on resting-state functional connectivity of the PCC.

Article Synopsis
  • Meditation can boost well-being, but beginners often struggle with recognizing and stopping their thoughts during practice, which can limit its benefits.
  • A study with 40 novice meditators explored whether personalized neurofeedback could help them better disengage from their thoughts while meditating.
  • The experimental group that received feedback showed improved mental control during meditation, resulting in better emotional well-being and mindfulness during a week of self-guided practice.

Background: Repetitive negative thinking (RNT) in major depressive disorder (MDD) involves persistent focus on negative self-related experiences. Resting-state fMRI shows that the functional connectivity (FC) between the insula and the superior temporal sulcus is critical to RNT intensity. This study examines how insular FC patterns differ between resting-state and RNT-induction in MDD and healthy participants (HC).
