Fig. 6. Typical taste receptor responses to chemostimulation of the medial sensillum at 1 s after initial contact. Traces are for a 500 ms period, and for each diet all traces are from the same larva. The letters S, M1 and M2 indicate the different types of cells we identified based on the characteristics described in the methods. None of the recordings in this data set included an example of an L cell.
