Generators of synchronous activity of the locus coeruleus during development.
The locus coeruleus is thought to play an important role in the development of the central nervous system through a coordinated release of noradrenaline. The influence of the locus coeruleus on its diverse targets is strongly synchronized by the existence of electrical and chemical coupling between neurones, afferent supply of the nucleus from restricted sources and diffuse innervation of target areas. Extensive coupling between neonatal locus coeruleus neurones produces rhythmic synchronized electrical activity and distributes afferent synaptic activity throughout the entire nucleus. The strength of electrical coupling declines with age but appears to persist to a limited extent in the adult.
