Electrical Measurement of Muscle Activity
This video provides a demonstration of how nerve-muscle connectivity is measured.
Neuroscientist Thomas Jessel explains that motor neurons form functional connections with specific target muscles and can activate the muscles in a coordinated manner. He then demonstrates how scientists can measure muscles flexing and extending by recording electrical signals in the muscles.
This animation is a clip from a 2008 Holiday Lecture Series, Making Your Mind: Molecules, Motion, and Memory.
