The nucleus locus coeruleus (LC) is a group of neurons situated close to the floor of the fourth ventricle at the upper border of the pons. The cells of the rat LC are homogeneous by certain criteria. Virtually all the cells contain noradrenaline and its synthesizing enzymes (Dahlström and Fuxe, 1964; Pickel et al., 1979), and, in the anesthetized animal, they all discharge action potentials at a rather regular and slow rate (0.5 to 2 Hz) (Korf et al., 1974).
