Signal time courses of BOLD fMRI measurements in rodents often show a damped oscillation which may superimpose with the expected hemodynamic response. In order to explore and characterize these oscillations, we performed EPI-BOLD measurements with high temporal resolution upon electrical paw stimulation. 55 % of the measurements showed oscillations with a frequency of 0.2 Hz. We could verify that these oscillations were induced by stimulation but did not affect the BOLD response. Consequently, hemodynamic response function models for statistical analysis are valid independently from the occurrence of oscillations.
