\lipsum[1-1]
Neuronal processing is inherently non-linear, mechanisms such as the spiking threshold, or recitication during synaptic transmission are central to neuronal computations. Here we address the consequences of nonlinear interactions between two sinewave stimuli in the context of an electrosensory cocktail party in weakly electric fish. In a previous field study, it was observed that an extremely weak intruder signal was detected despite the presence of a much stronger female signal. Modelling studies showed that, in some scenarios, the presence of the strong female signal leads to an improved intruder detection. This was associated with nonlinearities in neuronal processing. Theoretical work has shown that the presence of two independent periodic signals can lead to non-linear interactions. We here extend on this by applying the analysis of the second-order susceptibility to experimentally recorded primary electroreceptor afferents of the active (P-units) and the passive (ampullary cells) electrosensory system. Our combined experimental and modelling approach shows that nonlinear interactions can be found in these cells and depends on the level of intrinsic noise. We can further show that simple white-noise stimulation can be used to quickly access the second-order susceptibility of a system even when the system is driven by the amplitude modulation of a carrier such as the electric organ discharge of weakly electric fish. This method can thus be easily applied to describe nonlinear processing in any sensory modality whether they are driven by direct stimuli or amplitude modulations.

\section*{Author summary}
\lipsum[1-1]
Weakly electric fish use their self-generated electric field to detect a wide range of behaviorally relevant stimuli. Intriguingly, they show detection performances of stimuli that are (i) extremely weak and (ii) occur in the background of strong foreground signals, reminiscent of what is often described as the cocktail party problem. Such performances are achieved by boosting the signal detection through nonlinear mechanisms. We here analyze nonlinear encoding in two different populations of primary electrosensory afferences of the weakly electric fish. We derive the rules under which nonlinear effects can be observed in both electrosensory subsystems. In a combined experimental and modelling approach we generalize the approach of nonlinear susceptibility to systems that respond to amplitude modulations of a carrier signal.
