Abstract: The sense of smell is a complex chemosensory processing in human and
animals that allows them to connect with the environment as one of their chief
sensory systems. In the field of functional brain imaging, many studies have
focused on locating brain regions that are involved during olfactory
processing. Despite wealth of literature about brain network in different
olfactory tasks, there is a paucity of data regarding task design. Moreover,
considering importance of olfactory tasks for patients with variety of
neurological diseases, special contemplations should be addressed for patients.
In this article, we review current olfaction tasks for behavioral studies and
functional neuroimaging assessments, as well as technical principles regarding
utilization of these tasks in functional magnetic resonance imaging studies.
