Multi-focal ultrasound neuromodulation to the dorsal anterior cingulate cortex disrupts behavioural and neural pain processing.
Trial report in Nature communications, 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
Transcranial ultrasound stimulation (TUS) is a promising non-invasive neuromodulation technique for pain-related deep brain regions. This study aimed to investigate neural mechanisms underlying TUS effects on pain processing using neuroimaging. Thirty-two healthy participants underwent two double-blind, randomised sessions (active or sham). A tonic cold stimulus was applied during multifocal TUS applied to the dorsal anterior cingulate cortex (dACC), and during functional magnetic resonance imaging (fMRI) and magnetic resonance spectroscopy (MRS). While no significant main effect on pain intensity was observed, active TUS showed a significantly greater reduction in pain ratings between 28- and 55-minutes post-stimulation, suggesting a delayed analgesic effect. Active TUS altered sensory encoding, disrupting the relationship between temperature and pain intensity. There was increased functional connectivity between the dACC and the supplementary motor area, pre-motor cortex, mid-ACC and supramarginal gyrus, and altered salience network connectivity. Overall, these findings suggest dACC-TUS has multidimensional effects across behavioural and neural aspects of pain processing, supporting its potential therapeutic value.
