With a light odor, sensory neurons fire rapidly when exposed and return to normal when the odor is removed. PG neurons exhibit the same phenomenon. However, with a strong odor, PG neurons fire rapidly upon exposure and return to normal when the odor is removed. Sensory cells, on the other hand, upon exposure to the odor begin to fire but then stop, even with the odor present.

Mitral neurons exhibit the same phenomenon.
