A biomedical engineer poked some sensors into a single neuron (nerve cell) in a giant squid to
measure its electrical activity. The voltage signals coming out of the neuron are graphed below.
a) What is the approximate frequency of this signal in this time window? Show your
calculations.
b) How would the graph look different if the frequency was increased? Decreased?
