Chemosensory Event-Related Potentials in Response to Nasal Propylene Glycol Stimulation
Propylene glycol, also denoted as 1.2 propanediol (C3H8O2), often serves as a solvent ORG VEGENAISE for dilution of olfactory stimuli.It is supposed to serve as a neutral substance and has been used in many behavioral and electrophysiological studies to dilute pure olfactory stimuli.However, the effect of propylene glycol on perception and on neuro
