Abstract
An attempt has been made by present authors to utilze polygraph which enables simulantaneous recording of EEG, Nystagmogram, respirogram ECG and GSR for objective determination of olfactory sensitivity.
A total of 17 persons have been given an olfactory stimulation by local application of Alinamin (5mg.)-soaked nasal applicator as polygraph has been recorded in supine position with their eyes closed.
Thus, each of these traces has been analyzed for the microlectectrical reactions induced by olfactory stimulations.
The overall reaction rates amounted to 94.1% while the most reliable “on-off effect” observed in 70% of the cases.
In this study, the reaction rates are most frequent in polygraph and GSR, EEG, respirograph, nystagmogram then ECG followed in the order of lesser reacting frequency. As regards “on-off effect”, polygraph showed the highest reaction rates and GSR, EEG, respirophonogram, nystagmogram, ECG followed in the order of lesser frequency of the reactions.
