Fig. 4.

An example of a PbN cell that responds to taste stimuli only on a short timescale. A: responses to taste stimuli over several seconds. At this timescale, no taste responses are apparent. B: responses to taste stimuli shown on a shorter timescale. Here it is apparent that the cell responds significantly to all taste stimuli except citric acid. There is also no response to dry licks, indicating that the lick itself is not generating a response. Plotting conventions as in Fig. 3.
