The present invention provides a positioning device (1) for positioning a transcranial magnetic stimulation coil (15). The positioning device (1) comprises a support element (4) adapted for implantation at a cranial stimulation site of an animal, and at least one protrusion (6) connected to the support element (4) for extending transdermally when the support element (4) is implanted. The at least one protrusion (6) is adapted for mechanically connecting with the transcranial magnetic stimulation coil (15) for administering transcranial magnetic stimulation at said cranial stimulation site of said animal. In a further aspect, the invention provides in a kit of parts comprising such positioning device (1) and a transcranial magnetic stimulation coil (15). Such kit of parts may further comprise a stimulation pulse source (21) for supplying a pulsed electrical signal to the transcranial magnetic stimulation coil (15).
