Summary: Resilience refers to the ability to adapt successfully following stressful life events, and several key psychological factors have been consistently linked to it in functional MRI studies. These factors include emotion regulation, reward responsivity, and cognitive control. Additionally, emerging areas of study such as social cognition, active coping, and fear extinction may further facilitate resilience. The ongoing issues in neuroimaging study design need to be addressed to improve treatments for post-traumatic stress syndromes.

Summary: This study aimed to establish the role of the basal ganglia in fatigue in multiple sclerosis (MS) using functional connectivity measures. The results suggest that decreased local functional connectivity within the basal ganglia plays a key role in cognitive fatigue in MS. Increased global functional connectivity between the basal ganglia and the cortex may serve as a compensatory mechanism to reduce the impact of fatigue in MS.

Summary: This study aimed to test the effects of different tractography-based approaches for the reconstruction of subthalamic nucleus (STN) functional territories. Four parcellation pipelines were compared, and it was found that each parcellation provided consistent results in terms of location of the identified parcels, but with variations in size and shape. It is suggested that fine-tuning of tractography-based parcellation may lead to higher reproducibility and aid the development of an optimized surgical targeting protocol.

Summary: Brain atrophy has been observed in perinatally HIV-infected patients despite treatment, indicating potential neurological consequences of the infection. This study aimed to evaluate cortical thickness and subcortical gray matter volumes in PHIV patients and found thinner cortices and lower subcortical GM volumes in certain brain regions compared to HIV-negative controls. While no differences were found in neuropsychological performance or psychopathological symptoms, neuroimaging revealed structural alterations in PHIV patients. More research is needed to understand the impact of HIV on brain structure and identify potential risk and protective factors in these patients.

Summary: This study investigates the relationship between magnetic susceptibility changes and other microstructural and functional alterations in subcortical nuclei of Wilson's disease patients. It also explores the diagnostic utility of these MRI-related metrics. Results show that Wilson's disease patients exhibit increased susceptibility, widespread atrophy, and microstructural impairments in the basal ganglia. The study concludes that microstructural impairment of the basal ganglia and brain atrophy are useful neuroimaging biomarkers for assessing neurological impairment in Wilson's disease.

Summary: Safety learning creates associations between conditional stimuli and the absence of threat. Studies have shown that human safety learning is related to fear inhibition, positive affect, and memory processes. Animal models have also identified distinctions between acquisition and expression in safety learning. Therefore, the neurobiology of safety learning should be conceptualized along an acquisition-expression model.

Summary: Recent research has shown that sleep can inhibit the development of intrusive memory after trauma, possibly through consolidating and integrating memories. However, the neural mechanisms behind this effect are still unknown. In this study, researchers used fMRI recordings to examine the neural correlates of sleep on traumatic memory development in healthy participants. They found that sleep reduced the number of intrusive traumatic memories compared to wakefulness. Additionally, targeted memory reactivation during sleep showed a descriptive reduction in intrusions. These findings suggest the beneficial effects of sleep on traumatic memory and provide insights into potential neural predictors.

Summary: By analyzing simultaneous recordings of scalp EEG and unit activity, we found that the average firing activity of two medial temporal lobe areas can be estimated from EEG spectral features. Changes in firing activity in both areas and states can be predicted from scalp EEG frequency modulations.

Summary: The literature of neuroimaging meta-analysis, particularly the activation likelihood estimation (ALE) approach, has been thriving for over a decade. A meta-evaluation of these meta-analyses was performed to evaluate their design and reporting standards. The study found that the use of cluster-level family-wise error (FWE) correction method has become dominant, and there has been slight improvement in reporting on data redundancy elimination and providing input data. However, there is still room for improvement in terms of data and code availability statements and data submission to BrainMap.

Summary: Heightened maternal stress during pregnancy is associated with atypical brain development and an elevated risk for psychopathology in offspring. Supportive environments during early postnatal life may promote brain development and reverse atypical developmental trajectories induced by prenatal stress. Factors such as parental caregiving quality, environmental enrichment, social support, and socioeconomic status can moderate the effects of prenatal stress on infant brain and neurocognitive outcomes.

Summary: Healthy brain dynamics are characterized by a complex system that is far from thermodynamic equilibrium. However, Alzheimer's disease (AD) disrupts the time-reversal symmetry of brain activity, moving it towards equilibrium dynamics. Through the analysis of brain data from AD patients and healthy control subjects, it was found that AD is associated with a decrease in temporal irreversibility at global, local, and network levels, affecting multiple frequency bands. Specifically, frontal and temporoparietal regions were most affected at the local level, while limbic, frontoparietal, default mode, and salience networks were most compromised at the network level. Temporal reversibility was related to cognitive decline in AD and gray matter volume in healthy control subjects.

Summary: This study found that most participants showed little change in their depression and anxiety symptoms during the first year of the COVID-19 pandemic. However, there were divergent responses among some participants, with some showing improvements and others experiencing worsening symptoms during national lockdowns. Younger age, a history of mental health diagnosis, non-binary or self-defined gender, and unemployed or student status were significant predictors of membership in the high symptom groups.

Summary: In this study, the authors investigate the complex spatiotemporal dynamics in large-scale brain models. They show that destabilization of a synchronized oscillatory state can lead to the emergence of traveling waves and high-dimensional chaos. This work establishes a general route towards understanding spatiotemporal oscillations in the brain.

Summary: To address the lack of interventions for neurodegenerative diseases, this study combined deep learning with a model of whole-brain functional connectivity in Alzheimer's disease (AD) and behavioral variant frontotemporal dementia (bvFTD) patients. Disease-specific atrophy maps were used to modulate local parameters, revealing stable dynamics in the hippocampus and insula as indicators of brain atrophy in AD and bvFTD, respectively. By using variational autoencoders, the evolution of different pathologies and their severity were visualized in a low-dimensional latent space. Perturbing the model identified key regions specific to AD and bvFTD, allowing transitions from pathological to healthy brain states. Overall, this study provides new insights into disease progression and control in neurodegeneration through external stimulation and uncovers the underlying dynamic mechanisms driving functional alterations.

Summary: The AHEAD feasibility trial assessed the feasibility and acceptability of a group drumming programme in improving executive function, depression and anxiety symptoms, and social support among adolescents with HIV in rural South Africa. The trial included 68 adolescents who were randomly assigned to either receive weekly drumming sessions or no intervention. The results showed that the intervention was feasible and acceptable, with high rates of enrolment and retention. Although there were positive effects on depressed mood and some qualitative benefits, there were no significant effects on executive function or socio-emotional scales.

Summary: This service evaluation study describes a case series of five participants experiencing PTSD following recent traumas. Participants completed a shortened 6-week form of Internet-delivered Cognitive Therapy for PTSD (iCT-PTSD), which used fewer treatment modules and primarily focused on psychoeducation about PTSD, and two key treatment components, 'reclaiming your life' and trigger discrimination. Results showed that the intervention was associated with large reductions in symptoms of PTSD, depression, and anxiety at the 6-week timepoint, which were maintained at 3-month follow-up.

Summary: Previous studies on error processing have primarily focused on the posterior medial frontal cortex, but the role of other brain regions has been underestimated. This study used activation likelihood estimation meta-analyses to explore brain activity related to committing errors and responding successfully in interference tasks. It was found that the salience network and the temporoparietal junction were commonly involved in both correct and incorrect responses, indicating their general involvement in coping with situations that require increased cognitive control. Error-specific convergence was observed in the dorsal posterior cingulate cortex, posterior thalamus, and left superior frontal gyrus, while successful responding showed stronger convergence in the dorsal attention network and lateral prefrontal regions. Underrecruitment of these regions in error trials may reflect failures in activating the appropriate stimulus-response contingencies necessary for successful response execution.
