Multimodal Evidence for Hippocampal Engagement and Modulation by Functional Connectivity-Guided Parietal TMS
Zhuoran Li, Nicholas T. Trapp, Joel Bruss…·Jing Jiang
This study uses TMS combined with iEEG and fMRI to show that parietal TMS guided by hippocampal connectivity engages and modulates hippocampal activity, with effects related to individual FC strength and theta oscillations.

Volumetric Differences of Thalamic Nuclei are Associated with Post-Trauma Psychopathology
Nick Steele, Ahmed Tafsirul Hussain, C. Lexi Baird…·Rajendra A. Morey
The paper examines thalamic volume differences in trauma-exposed individuals with PTSD, MDD, and controls, finding specific volume reductions and associations with symptom severity and childhood trauma.

Densely sampled stimulus-response map of human cortex with single pulse TMS-EEG and its relation to whole brain neuroimaging measures
Yinming Sun, Molly V. Lucas, Christopher C. Cline…·Manish Saggar
The paper maps stimulus-response patterns in the human cortex using TMS-EEG and relates them to whole-brain neuroimaging measures from a single densely-sampled individual.

Distinct neurochemical influences on fMRI response polarity in the striatum
Domenic H. Cerri, Daniel L. Albaugh, Lindsay R. Walton…·Yen‐Yu Ian Shih
This study identifies neurochemical influences on fMRI response polarity in the striatum, showing opioidergic transmission contributes to negative signals while dopaminergic transmission is associated with positive signals.

Multimodal Imaging-Based Classification of PTSD Using Data-Driven Computational Approaches: A Multisite Big Data Study from the ENIGMA-PGC PTSD Consortium
Xi Zhu, Yoojean Kim, Orren Ravid…·Alan N. Simmons
This paper classifies PTSD vs. controls using MRI data from multiple sites, finding better performance when distinguishing PTSD from trauma-unexposed controls than trauma-exposed controls, and showing DVAE improves generalizability.

Smaller total and subregional cerebellar volumes in posttraumatic stress disorder: a mega-analysis by the ENIGMA-PGC PTSD workgroup
Ashley A. Huggins, C. Lexi Baird, Melvin Briggs…·John Harrison Krystal
This study finds smaller total and subregional cerebellar volumes in PTSD compared to controls using a large dataset and advanced parcellation methods.

A Comparison of Methods to Harmonize Cortical Thickness Measurements Across Scanners and Sites
Delin Sun, Gopalkumar Rakesh, Courtney C. Haswell…·Rajendra A. Morey
This paper compares four methods for harmonizing cortical thickness data across multiple sites and finds that ComBat-GAM is most effective in detecting case-control differences and age-related cortical thinning.

A translational approach to measuring the neural systems underlying approach-avoidance conflict in humans
Camarin E. Rolle, Ken Amemori, Noriah D. Johnson…·Amit Etkin
The paper introduces and validates a novel human task for studying approach-avoidance conflict, identifies associated neural patterns, and links them to trait anxiety.

Genetic factors influencing a neurobiological substrate for psychiatric disorders
Till F. M. Andlauer, Thomas W. Mühleisen, Felix Hoffstaedter…·Sven Cichon
The paper investigates genetic factors influencing a neurobiological substrate for psychiatric disorders and finds that a common genetic variant is associated with the substrate but not directly with disease risk.

A computational knowledge engine for human neuroscience
Elizabeth Beam, Christopher Potts, Russell Alan Poldrack, Amit Etkin
This paper develops a data-driven ontology for human brain structure-function mapping using computational methods applied to nearly 20,000 neuroimaging articles, revealing novel domain patterns and improved replicability.
