A neurological treatment apparatus includes a first endovascular device comprising a plurality of first electrodes extending along a first length in a distal portion of the first device, the distal portion of the first device being configured for endoluminal navigation into cerebral vasculature, and a second endovascular device comprising a plurality of second electrodes extending along a second length in a distal portion of the second device, configured for endoluminal navigation into the cerebral vasculature, such that electrostimulative current may be passed between the first and second electrodes.
