Change of Chemosensory Event-Related Potentials on Olfactory Stimulation as a Function of Odorant Concentrations

Change of chemosensory event-related potentials on olfactory stimulation as a function of odorant concentrations is discussed. According to the ascending method, from undetectable level to clearly detectable level, the dependency of shortening of the peak latency on the concentration of odorant was recognized as a rapid decrease of amplitude from the threshold level when results of our ascending trial were averaged. However, a much higher concentration of odorant did not always evoke a positive response and a shorter peak latency.
