Locus Caeruleus and Ergonomi.

The locus caeruleus, which has a tubular anatomical shape in the pons, affects almost the entire central nervous system despite its small size. Locus caeruleus which was first noticed about two centuries ago is the source of noradrenaline and is dark blue due to the neuromelanin pigment contained in its cells. This is why it is called coeruleus (sky blue) in Latin. This group of cells located bilaterally in the pons contains approximately 45.000-50.000 cells. In recent years we have much more information about the locus caeruleus due to developing technology and optogenetic studies, functional magnetic resonance imaging techniques. It is known that this anatomical device plays a key role in user characteristics such as attention, use, and stress. Because oculomotor functions reflect mental fruits, it has been the focus of attention especially for engineers working in the field of ergonomics. In this review study, it is aimed to reveal the anatomical structure, physiological characteristics and clinical importance of the locus caeruleus. [ABSTRACT FROM AUTHOR]
