Figure 2. Response patterns of the associated olfactory sensory neurons housed in three types of sensilla in male antennae of H. assulta.

For each type (or subtype) of sensilla, the left panels (A,C,E,G,I,K) show examples of the electrophysiological recordings. Black bars at the top of each panel show that duration of the stimuli. The right panels (B,D,F,H,J,L) report the spike frequencies (Mean ± SEM) which were calculated by counting the number of spikes during the first 200 ms of the response. Columns with the same letters are not significantly different at P < 0.05. Paraffin oil was used as control.
