Endosulfan Exposure Disrupts Pheromonal Systems in the Red-Spotted Newt: A Mechanism for Subtle Effects of Environmental Chemicals

A device called an electro-olfactogram, which measures electric impulses generated within cells, enabled the researchers to determine whether the cells recognized any of 65 sprayed odorants.

For 64 of the odorants, the electro-olfactogram detected similar responses from both infected and uninfected nasal cells.
