The gray matter volume of bilateral inferior temporal gyrus in mediating the association between psychological stress and sleep quality among Chinese college students

Li Zhang et al.

Summary: This study found a negative correlation between psychological stress and sleep quality, with this association partially mediated by the region of the bilateral inferior temporal gyrus. The results highlight the essential role of the brain region related to emotional processing in improving sleep quality, emphasizing the strong link between sleep quality and psychological stress.

Disrupted fronto-parietal network and default-mode network gamma interactions distinguishing suicidal ideation and suicide attempt in depression

Zhongpeng Dai et al.

Summary: This study investigated the relationship between negative emotion processing deficits and suicide risk in patients with Major Depressive Disorder. The findings suggest that gamma oscillations play a critical role in the progression from suicidal ideation to suicide attempt. The inter-network gamma connectivity between the fronto-parietal control network (FPN) and default mode network (DMN) may be the key neuropathological interaction underlying this progression.

Resting-state functional connectivity of the amygdala in major depressive disorder with suicidal ideation

Weicheng Li et al.

Summary: This study found distinct patterns of brain functional connectivity between depressive patients with suicidal ideation and without. The suicidal ideation group exhibited different amygdala resting-state functional connectivity patterns, with specific connections associated with cognitive functions.

Neural Correlates Associated With Suicide and Nonsuicidal Self-injury in Youth

Randy P. Auerbach et al.

Summary: Currently, there is no definitive neural marker that accurately reflects suicidal thoughts and behaviors as well as non-suicidal self-injury, and research on youth in this field is more limited compared to adults. Through neural imaging studies, it has been found that suicidal behaviors and non-suicidal self-injury in adolescents may be associated with neural alterations. Future longitudinal studies will help identify new targets for treating youth with STBs and NSSI.

Alteration of single-subject gray matter networks in major depressed patients with suicidality

Huiru Li et al.

Summary: Previous studies have shown regional brain alterations and functional connectivity in depressed suicidal patients. This study aimed to explore the GM of depressed suicidal brains from the single-subject structural network level. Results showed decreased segregation and weaker integration in the GM network of suicidal patients.

Dysfunction of default mode network is associated with active suicidal ideation in youths and young adults with depression: Findings from the T-RAD study

Cherise R. Chin Fatt et al.

Summary: The study investigated the relationship between suicidal ideation and resting-state functional connectivity in youths and young adults, finding that stronger connectivity of the default mode network (DMN) with the striatum was associated with higher suicidal ideation, while weaker connectivity of the limbic network with the hippocampus, DMN, dorsal attention network, and executive control network was associated with higher suicidal ideation.

Low dose oral ketamine treatment in chronic suicidality: An open-label pilot study

Adem T. Can et al.

Summary: Oral ketamine treatment for chronic suicidality showed a significant reduction in suicidal ideation after 6 weeks, with 69% of participants achieving clinical improvement within the first 6 weeks. This suggests that oral administration could be a feasible and tolerable alternative treatment option for chronic suicidality, with results consistent with IV ketamine trials.

Effective Connectivity between Major Nodes of the Limbic System, Salience and Frontoparietal Networks Differentiates Schizophrenia and Mood Disorders from Healthy Controls

Sevdalina Kandilarova et al.

Summary: This study investigated the differences in connectomes between psychiatric patients and healthy controls, revealing that dysfunction in the self-regulation of the salience network may underpin major mental disorders. Key connectome features differentiate mood disorders from schizophrenia, and can serve as potential imaging biomarkers.

Pharmaco-Magnetic Resonance as a Tool for Monitoring the Medication-Related Effects in the Brain May Provide Potential Biomarkers for Psychotic Disorders

Katrin Aryutova et al.

Summary: The complex interaction between the dopamine and glutamate neurotransmitter systems provides the long-needed etiological concept for schizophrenia. These systems play a role in the origin of positive and negative symptoms in the mesolimbic and mesocortical systems. Pharmaco-magnetic resonance imaging can translate this knowledge into effective therapeutic results.

Ketamine decreases neuronally released glutamate via retrograde stimulation of presynaptic adenosine A1 receptors

Vesna Lazarevic et al.

Summary: Ketamine reduces glutamate release by antagonizing NMDA receptors and neuronally derived glutamate, which can be blocked by AMPA receptor and adenosine A1 receptor antagonism, contributing to its antidepressant actions.

Dissociating default mode network resting state markers of suicide from familial risk factors for depression

Henry W. Chase et al.

Summary: The neural signatures of suicide risk, as well as depression, are likely influenced by a combination of specific and non-specific factors. In this study, differences in resting state connectivity and neural activity were observed between individuals with a family history of major depressive disorder and those with a personal history of suicidal thoughts and behaviors. These findings emphasize the relevance of default mode network (DMN) functional connectivity for mood disorders and underscore the importance of differentiating biological factors related to mental disorders versus suicidal thoughts and behaviors.
