Distinct fNIRS Inter-Brain Coupling Patterns for Cooperation versus Competition in a Tennis Game.
Article in Social cognitive and affective neuroscience, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Cooperation and competition represent two fundamental modes of social interaction, yet their underlying neural mechanisms remain incompletely understood. Functional near-infrared spectroscopy hyperscanning, enabling simultaneous measurement of hemodynamic activity across individuals, offers unique insights into the neural substrates underlying naturalistic interactions. Using this technique, we investigated cross-channel inter-brain coupling (IBC) between interacting individuals during cooperative and competitive play in a motion-sensing tennis game. Compared to resting-state and solo gameplay with observation, both conditions elicit significantly enhanced not only IBC between the dyads' sensorimotor regions, but also cross-regional coupling between one participant's sensorimotor cortex and the other's dorsolateral prefrontal cortex (DLPFC) as well as temporoparietal junction, suggesting the contribution of high-order cognition networks to the observed IBC. Notably, competitive interactions produce stronger cross-regional IBC between DLPFC and sensorimotor regions than cooperative ones, implying an intensified demand for cognitive control during competition. Conversely, cooperation enhances neural coupling between team-mates within their prefrontal cortices, which could reflect shared goal representations. Behavioural cooperation performance is negatively correlated with the DLPFC-sensorimotor IBC. These spatially distinct patterns of condition-dependent neural coupling advance our understanding of the neural underpinnings of naturalistic social interactions.
