Mapping Brain Activation to Odorants in Patients with Smell Loss by Functional MRI J Comput Assist Tomogr 22:96-103, Levy,L.M.,et al, 1998 See this aricle in Pubmed Article Abstract Brain activation to each stimulus was lower in each section in patients compared with normal subjects and reached statistical significance for mean activation for each odor and in six of nine individual sections studied.Activation of patients was found in regions of medial and posterior temporal cortex.These results demonstrate quantitative CNS changes in smell function in response to olfactory stimuli in patients with hyposmia,demonstrate a novel,objective method by which these patients can be identified,and provide maps of the CNS changes associated with their smell loss.
