Regional specialization of movement encoding across the primate sensorimotor cortex.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
The process by which the cerebral cortex generates movements to achieve different tasks remains poorly understood. Here, we leveraged the rich repertoire of well-controlled primate locomotor behaviors to study how task-specific movements are encoded across the dorsal premotor cortex (PMd), primary motor cortex (M1), and primary somatosensory cortex (S1) under naturalistic conditions. Neural population activity was confined within low-dimensional manifolds and partitioned into task-dependent and task-independent subspaces. However, the prevalence of these subspaces differed between cortical regions. PMd primarily operated within its task-dependent subspace, while S1, and to a lesser extent M1, largely evolved within their task-independent subspaces. The temporal structure of movement was encoded in the task-independent subspaces, which also dominated the PMd-to-M1 communication as the movement plans were translated into motor commands. Our results suggest that the brain utilizes different cortical regions to serialize the motor control by first performing task-specific computations in PMd to then generate task-independent commands in M1.
