Hippocampal subfield-specific imaging in depression: the translational power of ultra-high field MRI.
Review in Translational psychiatry, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Major depressive disorder is a highly prevalent psychiatric condition characterized by diverse symptom profiles and variable treatment responses. The hippocampus has long been implicated in its pathophysiology, yet most human neuroimaging studies have treated it as a unitary structure, overlooking the distinct cytoarchitecture and connectivity of its subfields. Preclinical research demonstrates that subfields such as cornu ammonis 1 (CA1) and the dentate gyrus (DG) are differentially involved in stress susceptibility and antidepressant response. However, limited spatial resolution of conventional human neuroimaging has constrained in vivo characterization of these subfields and testing of translational hypotheses in humans. While advances in high resolution 3 tesla (T) imaging have improved subfield delineation, ultra-high field (UHF) MRI (7 T and above) extends these capabilities by combining whole-brain coverage with greater sensitivity to structural, functional and microstructural contrasts. This review synthesizes emerging applications of UHF MRI in depression, highlighting its advantages over conventional imaging approaches and early evidence for subfield-specific alterations. While most studies to date have focused on volumetric analyses, preliminary literature suggests structural and microstructural abnormalities in CA1 and DG, paralleling preclinical findings and implicating these subfields in network-level dysfunction and plasticity-related mechanisms. Future research should move beyond volumetric analyses to adopt more diverse MRI protocols capable of probing how subfield-specific architecture contributes to whole-brain networks and relates to clinical heterogeneity. UHF MRI offers a powerful platform to test mechanistic hypotheses derived from animal models, identify subfield-specific biomarkers, and ultimately guide personalized interventions targeting hippocampal circuits most relevant to individual symptom profiles.
