155:. Once students have collected data, they use analysis tools to measure the amplitude and frequency, plus a wide range of other values from the electrical signals. The analysis process allows students to make general comparisons with the data. They can compare their results to published normal values, or the values before and after a subject performed a specified task. They can also compare results with other students in the lab. The software is available in English, French, Spanish, Italian, Japanese and Chinese.

and had a unit of electrical measurement named in his honor (the Volt). These early researchers studied "animal electricity" and were among the first to realize that applying an electrical signal to an isolated animal muscle caused it to twitch. The Biopac
Student Lab uses procedures similar to Count
