Brain activation under right ventricular stimulation.

Coordinates are relative to bregma in the right-left (x), superior-inferior (y), and anterior-posterior (z) directions (mm). Voxels in each cluster are expressed as the number of voxels exceeding the threshold of P<0.05 corrected for multiple comparisons using the false discovery rate in the second-level analysis (Group) and P<0.005 uncorrected for multiple comparisons in the first-level analyses of rats 13–24. Blanks indicate that no voxels exceeded the significance threshold in the right somatosensory cortex.
