  4. 3. Olfactory sensitivity of human subjects for six predator odorants

    University essay from Institutionen för fysik, kemi och biologi; Tekniska högskolan

    Author : Amir Sarrafchi; [2012]
    Keywords : Human olfactory sensitivity; predator odor; sulfur-containing odorant; sex difference;

    Abstract : The purpose of the present study was to determine olfactory detection thresholds in human subjects for a set of six sulfur-containing odorants which are known to be components of mammalian predator odors. Using a threealternative ascending staircase procedure, the olfactory sensitivity of 12 healthy adult human subjects, 6 males and 6 females was assessed with 2-propylthietane, 2,2-dimethylthietane, 3-mercapto-3-methylbutan-1-ol, 3-mercapto-3- methylbutyl formate, 3-methyl-1-butanethiol, and methyl-2-phenylethyl sulfide.
