What is the coeruleus locus?
Locus coeruleus is an area of the brain that acts to regulate the level of activity in the brain. He is closely involved in the waking and sleeping cycle and also plays a number of other roles. The name of this structure literally means "blue spots", a reference to a bluish color, which is in fresh brain tissue due to the presence of cells that contain higher concentrations of melanin. The coeruleus locus is relatively small, but has a long range. Despite the fact that it is a small nubbin in the brain, its neurons are associated with many areas of the brain, formed with areas responsible for sensory processing and many other activities. You could think of the coeruleus locus as a very long spider prepared in the middle of the brain, while the legs touch key areas.
Noradrenalinproduction is moderated by the coeruleus locus. This structure decides how much noradrenaline to produce and when, which determines how alert and wake the brain. ForDuction of noradrenaline occurs in response to a sensory entry by which the coeruleus locus is sorted to determine the correct level of response. For example, when someone looks at the dog, the brain recognizes the animal as probably harmless and remains low at the low level of excitation. The charging wolf, on the other hand, would trigger an increase in noradrenaline, a high state of alertness and a stress reaction.
stress and panic reactions are an important part of what the coeruleus locus controls, but this structure is also involved in creating memories, processing emotions, motivation and attention. By relieving the level of alertness, the brain can cause it to be slow or more active, giving it more energy to focus or overload in response to stress. Coeruleus locus neurons are constantly active, processing and sown through information to identify relevant pieces that are used to regulate the "speed" of the brain, and so in.
The effects of the coeruleus locus can be observed when scanning the brain that measures brain activity. WhenThe flood of noradrenaline is released, the brain lights up, often in several areas when it kicks to a high gear. When people are slow or resting and the production of noradrenaline is low, the brain is appropriately inactive, with a lower level of noradrenaline to excite it, keep it in a less warning state.
