+\paragraph{Code and data accessibility}
+The P-unit model parameters and spectral analysis algorithms are available at \secret{\url{https://github.com/bendalab/punitmodel/tree/v1}}. The electrophysiological data of all the P-units and Ampullary cells analyzed here, the analysis scripts, and the scripts simulating the P-unit model responses are accessible at \secret{\url{https://doi.org/10.12751/g-node.4w8ebq}}.
 
 \paragraph{Baseline analysis}\label{baselinemethods}
 The baseline firing rate $r$ was calculated as the number of spikes divided by the duration of the baseline recording (median 32\,s). The coefficient of variation (CV) of the interspike intervals (ISI) is their standard deviation relative to their mean: $\rm{CV}_{\rm base} = \sqrt{\langle (ISI- \langle ISI \rangle) ^2 \rangle} / \langle ISI \rangle$. If the baseline was recorded several times in a recording, the measures from the longest recording were taken.
