Senior Project Week 7- Simulation

This week, we did more stimulation. This time, I took better notes in my notebook in order to better input the data into my analysis code (specifically, the gain on the iso-80 and the valhalla). We also used different methods to get rid of the background noise picked up by the recording electrode, such as purposefully flipping the polarity of the graph for every other average captured. Our conclusions from this week revealed to us that the narrowing of the nerve chord as you approach the posterior end might be a serious problem for our experiment. There is a certain distance needed to differentiate the actual measured compound action potential response from the general stimulation artifact. However, with that distance, if we stimulate from the head, where there are more nerves (due to the ganglion), and measure at the tail end, the nerve fibers begin to branch away from the main ventral nerve chord as you progress posteriorly, leaving only a few at the area of recording towards the tail end.
