Visit this site (http://openstaxcollege.org/l/neurolab)to see a virtual neurophysiology lab, and to observeelectrophysiological processes in the nervous system,where scientists directly measure the electrical signalsproduced by neurons. Often, the action potentials occur sorapidly that watching a screen to see them occur is nothelpful. A speaker is powered by the signals recorded froma neuron and it “pops” each time the neuron fires an actionpotential. These action potentials are firing so fast that itsounds like static on the radio. Electrophysiologists canrecognize the patterns within that static to understand whatis happening. Why is the leech model used for measuringthe electrical activity of neurons instead of using humans?
