Abstract

fetched live from OpenAlex

The ability to mentally simulate motor actions was studied in 25 patients with stroke. The duration of imagined and executed movements of the arm and leg was compared. Both executed and imagined movements took longer with the affected limbs than with the unaffected limbs. For both tasks, the duration of movements with the unaffected limbs was longer in the imagined than in the executed conditions, indicating a lack of temporal congruence on that side. Because the temporal uncoupling was found in the limbs contralateral to the intact hemisphere, we propose that this reflects a general slowing in motor imagery that is an indirect consequence of the lesion, rather than a deficit in movement representation within the unaffected hemisphere per se.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
