there is a linear relationship between motor neuron firing and wingbeat frequency. this is important for my experiments because it explains how I can change WBF through MN manipulations.
Importantly, higher wingbeat frequency does not recruit more or different motor units. it is purely the frequency of the MN population firing for different power production. the mechanism: DLMns adjust myoplasmic calcium levels to control wing power
just focus on the gray dots! This is one animal worth of data. As MN firing frequency increases so does wingbeat frequency. and this is tightly correlated within an animal. The exact MN firing frequency → wingbeat frequency is not the same for each animal.
