Interest in the fMRI of the human olfactory system has increased in recent years. The aim of this study is to build a cost effective MR olfactometer suitable for clinical and laboratory environments. An apparatus was built to determine the temporal resolution and the delay time of the custom-built olfactometer. Six healthy subjects participated in testing the olfactometer with six odorant stimuli. The olfactometer has a very short delay time, less than 1 second. Activations were found in the piriform cortex, insular cortex and DLPFC.
