Evolution of object identity information in sensorimotor cortex throughout grasp.
Article in Nature communications, 2026. 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
Reaching for and grasping an object seems a continuous process, yet somatosensory signals undergo dramatic state changes near the time of object contact. Tactile afferents start conveying contact forces, while on-going proprioceptive signals are altered as hand shape stops changing. How cortex maintains object identity in the presence of changing, multi-modal signals remains unknown. We quantified object-specific information in neurons of the primary motor cortex (M1) and somatosensory areas 3a, 3b/1, and 2 in male macaque monkeys. Surprisingly, despite the decrease in activity in each area immediately after contact, object identity information increased across sensorimotor cortex, particularly in purely cutaneous areas 3b/1, but also in multi-modal area 2. Uniquely among sensorimotor areas, object-specific information was present in M1 and 3a throughout grasp, although identity was encoded differently before and after contact. These shifts highlight the profound change in the complex coding of object identity in the sensorimotor cortex during grasp.
