P values for trend were derived from a general linear model; statistical significance was evaluated at P \ 0.-0.44.56 mL). This effect was not observed for the high nicotine concentration (effect side of stimulation: F = 0.05, P = 0.83).Discussion The objective on the experiments reported here was to investigate the interactions in between two chemical stimuli, menthol and nicotine, both of which activate the olfactory and trigeminal system. Far more especially, we wanted to understand regardless of whether menthol at distinctive levels modulates the perception in the burning and stinging sensations induced by nicotine stimuli. So that you can separate the modulatory effects from the direct sensory effects made by these two compounds, we chose to administer nicotine stimuli phasically, that's, short stimuli repeated every 1.5 min, as well as the modulatory menthol stimuli tonically. This also helped participants to clearly discriminate involving the intensity on the unique sensations they had to estimate.
