Presumably, these neurons reside in the same sensillum, although some cases of recordings from more than one sensillum cannot be excluded. Neurons may also occasionally be damaged by the penetrating electrode and therefore never be recorded or counted as not responding.
a, b and c represent neurons of different spike amplitude, from the highest to the lowest amplitude (see Fig. 2). NR/- indicates a non-responding neuron or that no neuron was found in this position (i.e. no spikes with this relative amplitude). The table does not include all neurons, since some contacts yielded just a single neuron.
