The goal of this effort has been to argue against the notion that oscillations and field potentials are epiphenomenal. What emerged is a conceptual, theoretical, and empirical analysis on what various electrophysiology entities mean and do for us. [1/n]

To get our analysis going, we introduce two distinctions. First, we delineate measurements and processes. Second, we separate causal and inferential relevance. We take these axes and analyse the relations between field potentials, electric fields, neurobiological processes, etc.

As we evaluate each arrow in the figure, we pay special attention to the causal effects of e-fields, which are the processes that field potentials are a measurement of. We review evidence for the coupling of such e-fields back to neural processes.

Next, we turn to oscillations specifically. There can be oscillations in processes and measurements, and one may happen without the other. We spell out criteria for inferring oscillations-in-process, and we argue oscillatory e-fields have special causal roles.

Finally, we outline a view in which oscillations in processes across levels of organization orchestrate neuronal computation via three processing syntaxes. We explain and consider empirical results in favor of each mode.

On the whole, we view our contribution to be one of clarification. If two scientists have starkly different conceptions in mind when they discuss oscillations in their writing or conversation, this will hamper empirical progress.
