These results indicate that, during surgery, monitoring of corticomuscular MEPs (which are related to I waves) is a much more sensitive method for the detection of immediate motor cortical damage than monitoring of corticospinal MEPs (D wave).
We devided these ten odors into 3 types. Type I: These odors were the first that failed to be recognized. Residual percentage (number of patients who can recognize this odor/number of all patients) was 15-35%. When, at the first examination, these odors could be recognized at whatever high threshold, the smelling sense for this odor was recovered after the treatment.Of the patients who could not recognize these ten odors, only 3-12% recovered completely, and about 60% did not recover at all. These were a-PEA, PHE, EXA, CAM. We suggest that these 4 odors are appropriate for the primary olfactory area.Type II: These odors do not fail to be recognized until the disturbance becomes serious. Residual percentage was 21-54%.After the treatment, the sense of smell recovered remarkably.Of the patients who at the first examination could not recognize these odors, 30% recovered completely and about 50% did not recover at all. These were CYC, VAL, UND, SCA. We suggest that these 4 odors have to do with the primary and the accessory olfactory area.Type III: These odors were recognized even when disturbance becomes serious. Residual percentage was 52-86%.Of the patients who could not, at the first examination, recognize these odors, 12-13% recovered completely, but about 40% did not recover at all. These were ACE, DIA.We suggest that for these 2 odors, the accessory olfactory areas play a very important role.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
