Abstract

To overcome the limitations of invasive neuromodulation systems, we introduce a wireless magnetomechanical approach for remote, minimally‐invasive deep brain stimulation (DBS) without chronically implanted hardware. This method leverages biocompatible magnetite nanodiscs (MNDs) with ground vortex magnetization, which undergo in‐plane transitions under low‐frequency alternating magnetic fields, generating localized piconewton‐scale torques. These torques engage endogenous mechanosensory pathways to modulate neural activity, enabling reversible stimulation without genetic modifications. Calcium‐imaging validated rapid neuromodulatory effects of MNDs in vitro and ex vivo, motivating the application of magnetomechanical DBS to the subthalamic nucleus in mice. We demonstrated remote control of motor behavior in wild‐type mice and significant restoration of motor function in a severe hemiparkinsonian model. Demonstrating efficacy at multiple experimental scales, this work establishes a clinically compatible, electrode‐free neuromodulation technology combining nanoscale engineering with mechanosensory signaling, paving the way toward a minimally‐invasive DBS approach suitable for outpatient use and for patients ineligible for conventional DBS.

Code

No file of the authors' code could be read here: it is described below, and read at its source.

Tracing map

Proposed by the machine: these links were found in the paper and verified at the source, without human review. The map will receive a Zenodo DOI once one of the paper's authors has validated it with their ORCID.

What the map holds:

• 3 repositories of the authors' code, each at its verified commit, with its license and how the link was found in the paper;
• 0 scripts, each with its path and the digest of its content;
• no match between paragraphs and code yet;
• neither the text of the paper nor the code itself.

Its JSON (tracing-map.json) is deposited on Zenodo with its DOI once the map is validated.

Data

No dataset and no data link were found in the paper.
