(I imagine the Results section like a dance with swords -- sometimes you are engaging your partner with the pointy end and sometimes you are gliding along side them).
While the introduction starts generally and narrows down to the specific hypothesis, the discussion starts with the interpretation of the results, then moves outwards to contextualize these findings in the general field.
The Discussion section is sort of an odd beast because it is here where you speculate, but must avoid rambling, guessing, or making logical leaps beyond what is reasonably supported for your data.
If you have unexpected findings, try to interpret them in terms of method, interpretation, even a restructured hypothesis; in extreme cases, you may have to rewrite your introduction. Previous reports of smooth tonotopic maps may have resulted from techniques that average the responses over multiple neurons.
Electrophysiological studies that reported precise tonotopy used electrode penetrations that were spaced by more than 200 μm and used multi-unit activity to determine frequency tuning Although this concern has not been thoroughly ruled out, it seems unlikely because, in at least one study, GABAergic interneuorns were loaded just as efficiently as neighboring pyramidal neurons using similar methodology This model could partially explain our results, including the heterogeneous micro-architecture and the decrease of signal and noise correlations with distance.
