Figure 1

Simultaneously recorded discharge rates of a pair of ON and OFF ORNs from a single sensillum exposed to the odor of lemon oil at constant concentration of 20%. The ON ORN (green) displayed smaller impulse amplitudes than the OFF ORN (blue). Inset The waveform sensitive template mechanism (spike2) was used to identify and sort action potentials from ON and OFF ORNs.
