Olfaction is possibly the most important way we interact with the environment contributing to our body’s physiological responses and likely responsible for 75% gustation, or our sense of taste. Less intensely than the Olfactory Nerve is stimulated, about 70% of odor molecules also stimulate the Trigeminal Nerve, giving us a more in-depth ability to determine dangers and pleasures through chemosensory stimulation from these molecules.
