Participants encountered the same conditions during an expression phase to investigate how the brain encodes predictive and unpredictive threat cues observed in others. Participants in Experiment 1 (n = 20, 14 female, 6 male) and Experiment 2 (n = 23, 9 female, 1 non-binary, 13 male) successfully learned threat contingencies, showing heightened threat expectations for predictive cues and unpredictable condition-onsets. Behavioral findings converged with neural (fMRI, Experiment 2) responses in the anterior insula during the expression phase. Reflecting the dynamic process of learning, amygdala activation in response to predictive threat cues displayed a linear decrease across trials. Interestingly, BOLD responses to others' pain that was predictable, were enhanced within the amygdala, insula and hippocampus, compared to unpredictable conditions.

This is partly due to differential cortico-striato-thalamo-cortical networks (CSTC) engagement across stimulation in relevant anatomical regions. This study compared the structural and functional connectivity profiles of three relevant anatomical-regions that have also served as target for DBS in different centers for trOCD: the nucleus accumbens/anterior-limb of the internal-capsule (NAc/ALIC), the medial forebrain bundle (MFB), and the anteromedial subthalamic nucleus (amSTN). We analysed in a retrospective, observational, single-center cohort the structural connectivity on patient-specific space, using structural and diffusion MRI data from 22 trOCD patients treated with NAc/ALIC DBS at the University Hospital Cologne. For this end, Whole-brain probabilistic-tractography using single-shell-three-tissue constrained-spherical-deconvolution was applied to reconstruct patient-specific structural connectivity matrices. From whole-brain tractograms, target-specific streamline subsets were selected using ROI-based inclusion criteria using 2 mm radius spheric stereotactic ROIs representing clinically relevant trOCD-DBS target regions. Afterwards, Structural connectivity matrices were extracted using Spherical-deconvolution informed filtering of tractograms (SIFT) streamline count, fractional anisotropy (FA), and mean diffusivity (MD) across 13 cortico-subcortical regions implicated in OCD pathophysiology. Thereafter, we characterized each target's connectivity to key OCD functional networks derived from meta-analytic functional connectivity maps. NAc/ALIC demonstrated stronger structural fronto-limbic connectivity: medial-orbitofrontal cortex, anterior-cingulate, insula, and accumbens (p < 0.0001), associated with the affect (AN), salience (SN), default-mode (DMN), and reward-motivation (RMN) networks anatomical hubs. The MFB predominantly connected with reward-related regions: pallidum and rostral-middle-frontal cortex (p < 0.0001). The amSTN showed to be mainly connected to SN and the cognitive/motor control network (CMCN): precentral and paracentral gyri (p < 0.0001). These exploratory findings suggest that clinically relevant trOCD-DBS targets may engage distinct but partially overlapping tractography derived structural networks and meta-analytic functional networks. The observed connectivity profiles may help generate hypotheses about symptom-specific networks for future DBS planning. Overall, these results support the proof-of-concept value of patient-specific probabilistic tractography in trOCD.

A complementary approach is to examine case-control contrasts to identify SUD-specific neural architecture while mitigating effects of task-design variability. We conducted a systematic literature search and an activation likelihood estimation (ALE) meta-analysis to identify convergence effects in the contrast drug > control cues between SUD and control groups. ALE results were supplemented by assessing behavioural domains, meta-analytic connectivity profiles, robustness to publication bias, and study-level modulators using penalised logistic regression. The ALE analysis revealed one reliable convergence cluster in the ventral anterior cingulate cortex (vACC), associated with reward, reasoning, and social cognition. Penalised logistic regression indicated that contributions to this cluster were less likely in alcohol DCR-studies and were sensitive to matching conditions for human content. vACC DCR effects contrasted with neutral control cues were invariant across abstinence periods, whereas vACC DCR contrasted with natural reward cues declined with longer abstinence. This meta-analysis replicates context-sensitive SUD-specific DCR convergence in vACC regions intersecting reward pathways and the default-mode network, while reliable striatal convergence was not observed.

While these dimensions have been extensively studied in isolation, their joint contribution to SI and MDD remains unclear. This study integrates multi-modal data to elucidate these synergistic effects and develop robust models for individual-level risk stratification. Leveraging longitudinal multi-modal data from 13,085 UK Biobank participants, we integrated genomic, proteomic, and social connection profiles. We developed interpretable risk scores using a rigorous supervised machine learning framework encompassing diverse linear and ensemble classifiers. Permutation importance was employed to quantify feature contributions and derive transparent, weighted risk metrics across diverse classifiers. These scores were validated through association, interaction, and mediation analyses. Social connection-based risk scores significantly differentiated cases and controls across the two suicidal ideation phenotypes at 2017 and 2023 with cross-sectional analyses (AUCs: 0.70 - 0.73), outperforming proteomic-only models. Functional dimensions of social connection emerged as the most informative predictors. Longitudinal analyses revealed that social risk scores at baseline predicted suicidal ideation onset six years later, independent of demographic covariates. Interaction analyses demonstrated that polygenic risk for suicide attempt significantly interacted with both social and proteomic risk features in relation to depression. Structural equation models further confirmed that social disconnection acts as a key mediator linking genetic predisposition to MDD and SI. Social disconnection is a critical risk factor mediating the impact of genetic vulnerability on psychiatric outcomes.
