We report preliminary results of simultaneous recordings of BOLD fMRI and electrophysiological responses from conscious rabbits during whisker stimulation at frequencies of 10 75Hz. Our data demonstrate strong correlations of BOLD fMRI responses with neuronal activity. This work suggests a useful model system to study the neurophysiological base of fMRI responses.
