The recalibration of corrective responses to sustained perturbations (e.g., constant force) altering one's movement contributes to this flexibility. We asked whether the recalibration of corrective actions involve cerebral structures using stroke as a disease model. We characterized changes in muscle activity in stroke survivors and control subjects before, during, and after walking on a split-belt treadmill moving the legs at different speeds. The recalibration of corrective muscle activity was comparable between stroke survivors and control subjects, which was unexpected given the known deficits in feedback responses poststroke. Also, the intact recalibration in stroke survivors contrasted their limited ability to adjust their muscle activity during steady-state split-belt walking. Our results suggest that the recalibration and execution of motor commands are partially dissociable cerebral lesions interfere with the execution, but not the recalibration, of motor commands on novel movement demands. Copyright © 2020 de Kam et al.Mary Shelley's Frankenstein has captured the public imagination ever since it was first published over 200 years ago. While the narrative reflected 19th-century anxieties about the emerging scientific revolution, it also suggested some clear moral lessons that remain relevant today. In a sense, Frankenstein was a work of bioethics written a century and a half before the discipline came to exist. This paper revisits the lessons of Frankenstein regarding the creation and manipulation of life in the light of recent developments in stem cell and neurobiological research. It argues that these lessons are becoming more relevant than ever. © Author(s) (or their employer(s)) 2020. No commercial re-use. See rights and permissions.
