Neuronal signaling. To support the general function of the nervous system, neurons have evolved unique capabilities for intracellular signaling (communication within the cell) and intercellular signaling (communication between cells).
Because of this, gyroscopes are useful for measuring or maintaining orientation. Invention History. The gyroscope was invented in 1852 by the French experimental physicist Leon Foucault (1819-1868) as part of a two-pronged investigation of the rotation of the earth.
(jÄ«â²rÉ-skÅpâ²) An instrument consisting of a disk or wheel that spins rapidly about an axis like a top. The spinning motion keeps the axis fixed even if the base is turned in any direction, making the gyroscope an accurate navigational instrument and an effective stabilizing device in ships and airplanes.
