Question

When large populations of neurons are relatively synchronously activated, have an open field organization, and received similar inputs (e.g., excitatory), then a field potential is generated. This is called a local field potential when recorded in the brain tissue, and a far field potential when recorded at some distance away. One example of a far field potential is a(n)

Answer 1

The correct answer is A median motor response with the recording electrode over abductor pollicis brevis.

The electric field is the region around an electric charge in which it will manifest its properties. It is similar to the concept of gravity studied in Gravitation. Gravity is the interaction between one body of mass and another, but it does not need to have contact between the bodies, it is enough that one body is within the gravitational field of another.

If another electric charge q is placed in place of that point, an electric force F will appear, as has already been studied in the Coulomb Law summary.

The direction of the electrical force will coincide with the direction of the field when the charge q is positive and the opposite direction when the electrical charge is negative.
