Neurocognitive Dynamics of Translating Information From a Spatial Map Into Action.
Article in Psychophysiology, 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
How do we translate information from a spatial map to action in our immediate surroundings? Despite the widespread use of various tools for orientation, from paper maps to GPS, this fundamental question remains unanswered in our understanding of human spatial navigation. To investigate this, we implemented a perspective-taking task in immersive virtual reality combined with mobile EEG, aiming to disentangle the neurocognitive processes involved. Thirty-eight young adults were presented with a virtual 2D map in which we manipulated both the perspective shift and the physical angle of rotation required to align with a target, as well as the congruency between these two variables. Behaviourally, angular error during pointing increased slightly and linearly with perspective shift. However, the relationship between rotation angle and accuracy revealed a non-linear pattern, with better performance around the antero-posterior bodily axis. Regarding congruency, angular error increased for incongruent trials, but only when the perspective-taking angle exceeded 90°. At the neural level, activity in the retrosplenial complex (RSC) revealed a sequential organization with alpha-band modulation during perspective shift, followed by beta-band activity reflecting preparation for the required physical rotation. In addition, incongruency between perspective-taking and physical rotation increased beta activity in the left temporo-parietal junction (lTPJ). Overall, these findings demonstrate the value of immersive virtual environments to investigate the neural correlates of real-world navigation and the complexity of perspective-taking mechanisms.
