Neural correlates of acute task-related stress in humans: a systematic review and coordinate-based ALE meta-analysis.
Synthesis in Brain imaging and behavior, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Stress is a major risk factor for psychiatric disorders, yet the whole-brain neural signature of acute task-related stress remains incompletely defined, particularly for stress-related decreases in activation. We conducted a PROSPERO-registered systematic review and activation likelihood estimation (ALE) meta-analysis of English-language, peer-reviewed human task-based functional MRI (fMRI) studies published between January 2000 and November 2025. Eligible studies reported whole-brain stereotactic coordinates for stress versus matched non-stress control conditions. Stress > control and control > stress contrasts were analysed separately in GingerALE 3.0.2 using random-effects ALE with cluster-level family-wise error correction. Eighty-nine studies met inclusion criteria. The stress > control analysis included 85 experiments from 84 studies (2,810 participants; 1,350 foci), whereas the control > stress analysis included 25 experiments from 25 studies (922 participants; 263 foci). Stress > control showed convergent activation in a bilateral network including the anterior insula and inferior frontal operculum, dorsal anterior cingulate and supplementary motor area, thalamus, striatum, lateral frontal and parietal cortex, and left amygdala/parahippocampal gyrus. Control > stress yielded a single right parahippocampal-amygdala cluster. Thus, across heterogeneous acute stress-related challenges, the task-based fMRI literature was characterized more by reproducible activation increases across salience, arousal, and action-readiness systems than by consistent deactivation. These findings provide an updated trans-paradigm coordinate-based reference map for stress neurobiology, while acknowledging that the pooled convergence may partly reflect neural responses to salience or task demand that are shared across paradigms.
