Cumulative effect on regional cerebral blood flow (rCBF) by concomitant caudal zona incerta (cZi) and pedunculopontine (PPN) stimulation

Projections of statistical parametric maps showing areas of significant rCBF increases compared to baseline induced by deep brain stimulation of the cZi alone, of the PPN alone, and of combined PPN and cZi. The figure shows the cumulative effect on rCBF by concomitant PPN and cZi stimulation. The areas are superimposed on axial and coronal sections of the averaged T1 MRI in Montreal Neurological Institute space available in SPM. The colorstripe indicates t values.
