 %General understanding of the effects of changes in current properties on neuronal firing may help to fill the need to understand the impacts of ion channel mutations on neuronal firing. 
-However the effect of a given channelopathy on different neuronal types across the brain is often unclear and not feasible to experimentally obtain. Different neuron types have different ion current compositions \textcolor{red}{(cite Berens and Allan Institute)} and therefore likely respond differently to changes in the properties of one current.

+  The expression level of an affected gene can correlate with firing behaviour in the simplest case \citep{Layer2021} \textcolor{red}{(cite other Papers?)}, however if a gating property is altered substantially this can have complex consequences.
 
 For instance, altering relative current amplitudes can dramatically influence the firing behaviour and dynamics of neurons \citep{rutecki_neuronal_1992, pospischil_minimal_2008,Kispersky2012, golowasch_failure_2002, barreiro_-current_2012, Noebels2017, Layer2021}, however other current parameters impact neuronal firing as well. In extreme cases, a mutation can have opposite effects on different neuron types. For example, the R1629H SCN1A mutation is associated which increased firing in interneurons, but decreases pyramidal neuron excitability \citep{Hedrich14874}\textcolor{red}{(and the other paper?)}.  %not sure which paper you mean Lukas
