OBJECTIVE
To investigate the olfactory origin of the event-related potential (OEP) by evaluating OEP and standardized psychophysical measures in patients with congenital anosmia.
METHODS
Olfactory function was evaluated by OEP and standardized psychophysical measures including smell identification
Olfactory function was evaluated by olfactory event-related potentials and standardized psychophysical measures including the Smell Identification Test and odor detection threshold tests for 3 chemosensory stimulants in 9 subjects with isolated congenital anosmia and 9 age- and gender-matched
OBJECTIVE
To explore the brain activation mapping following odor presentation with event -related functional magnetic resonance imaging.
METHODS
Ten healthy young volunteers with normal sense of smell and 5 anosmia patients, all right-handed, underwent routine otorhinolaryngological examination and
Experimental anosmia induced by 1% ZnSO4 solution triggered some structural and functional changes in olfactory epithelium of strain C57BL/6 mice. It was stimulated by various odors: isoamyl acetate, butyl acetate and some substances present in mice urine. It was registered that the rate of
Recent studies from the University of Arizona indicate that normal subjects, both college students and the elderly, can register the presence of low-intensity odors in the electroencephalogram (EEG) in the absence of conscious awareness of the odors. The experimental paradigm involves subjects
Olfactory sensitivity to two odorants, isoamyl acetate and androstenone, was assessed in 19 male schizophrenic patients and 10 control subjects. Tests were performed during a drug-free period and 2-3 weeks after initiation of neuroleptic drug therapy. Olfactory sensitivity in schizophrenic patients
