Neurobehavioral performance in human volunteers during inhalation exposure to the unpleasant local irritant cyclohexylamine

► Human volunteers were exposed in a whole-body 4 h inhalation study. ► We use 3 workplace relevant levels of cyclohexylamine in a within-subject design. ► Chemosensory (objective, subjective) effects increased with cyclohexylamine levels. ► No exposure related deficits occurred in attention, response shifting, inhibition. ► No neurobehavioral deficits despite strong unpleasant chemosensory exposure
