Figure 2.

Toluene dose-dependently alters the activity of a wide range of ion channels. Color bar indicates relative range of concentrations of toluene with odor threshold and huffing concentration indicated. Position of ion channel along the x-direction indicates relative sensitivity of individual ion channels to toluene while position along the y-direction indicates inhibition (below dotted line) or potentiation (above dotted line). Toluene has no appreciable effect on ion channels that overlay the dotted line. Underline indicates data collected in the author's laboratory.
