Olfaction plays an important role to detect environmental risk, taste the food, and performs various additional roles crucial to the nutrition, mood and memory. But it has been overlooked compared with other sensory organs, such as vision or hearing function. Recently, a variety of studies associated with olfactory system are in progress from periphery to central area. This review shows the brief summary of the recent ongoing study on olfaction.

Kallman syndrome is characterised by hypogonadotrophic hypogonadism and anosmia. T1 weighted MR coronal images show the bilateral absence or hypoplasia of olfactory bulbs, tracts, and sulci. We report the MR findings of Kallmann syndrome and revew the literature.

Congenital anosmia is usually described as a familial disorder in association with various sexual and other developmental abnormalities. Congenital anosmia occurring as an isolated defect in a single family member is extremely rare. That is said to exist when a patient has no recall of smell sensation dating from early childhood. We report two cases of isolated agenesis of the olfactory bulbs and tracts unrelated to pathological, syndromic diseases. We outline the investigations which should be undertaken in such cases.

Objective: To report the case of a woman who underwent smell training for post-infectious olfactory dysfunction presumably from COVID-19. Methods: Design: Case Report. Setting: Tertiary Private Training Hospital. Patient: One. Result: A 41-year-old woman who developed olfactory dysfunction attributed to COVID-19 underwent smell training. At baseline, her responses were mostly “no smell,” and those reported as “can smell a bit” were rated as distorted. After three months, she could now smell items that she previously could not smell, but these smells were still distorted. At the time of this writing, she was on her 4th month of smell training. Conclusion Although we cannot rule out spontaneous resolution of anosmia in our patient, we would like to think that smell training contributed to her recovery of smell.

Olfactory processing involves a large number of central olfactory structures, interconnected with each other in complex fashion, and incorporating both feed forward and feed back interaction. Thus understanding how these structures in odor acquisition, perception, and memory perform functional roles is a central question in olfactory disorders that can only be addressed using a combination of approaches, including neuroimaging, neurophysiology and behavioral analyses. Recent whole-brain imaging studies have shown that multiple diverse neural structures become activated during tasks involving olfactory stimulation. This article reviews the current understanding of anatomy, sensory physiology of central olfactory structures. Especially the sensory physiology of main olfactory bulb, pyriform cortex, and orbitofrontal cortex will be emphasized here.
