Abstract

To move your hand, your corticospinal tract fires—like the stepping on the car’s gas pedal. However, when your hand is at rest and not moving, besides not pressing on the gas pedal, think of a parking brake which is in the “on” position and keeping your hand at rest. The basal ganglion is the parking brake. When it comes time to move your hand, milliseconds before the movement, you need to turn the brake “off.” The following schematics focus on how we turn the brake on or off. Lesions in the basal ganglia can disrupt the break and can lead to tremors.
