Journal Compilation © Federation of European Neuroscience Societies and Blackwell Publishing Ltd</p> Electron and light microscopic photographs of the sensillum type are shown in (A) and (B) , respectively. (C) Spontaneous activity of the ORNs housed in the sensillum reveals differences in spike amplitude between A and B neurons. Distribution of spike amplitudes of the two neurons is shown in (D). In response to a 0.5 s odour stimulation, the ORNs exhibited two modes of responses, excitatory when they were stimulated with 2-butoxyethanol (2BE) and indole (E and F), and inhibitory when they were stimulated with propionic acid (G). Filled and open circles indicate large and small action potentials from the A and B neurons, respectively
