Noradrenergic Cell Group A6
Noradrenergic cell group A6 is a group of cells fluorescent for noradrenaline that are identical with the locus ceruleus The locus coeruleus () (LC), also spelled locus caeruleus or locus ceruleus, is a nucleus in the pons of the brainstem involved with physiological responses to stress and panic.

Noradrenergic Cell Groups
Noradrenergic cell groups refers to collections of neurons in the central nervous system that have been demonstrated by histochemical fluorescence to contain the neurotransmitter norepinephrine (noradrenalin).

Locus Ceruleus
The locus coeruleus () (LC), also spelled locus caeruleus or locus ceruleus, is a nucleus in the pons of the brainstem involved with physiological responses to stress and panic. It is a part of the reticular activating system. The locus coeruleus, which in Latin means "blue spot", is the principal site for brain synthesis of norepinephrine (noradrenaline). The locus coeruleus and the areas of the body affected by the norepinephrine it produces are described collectively as the locus coeruleus-noradrenergic system or LC-NA system. Norepinephrine may also be released directly into the blood from the adrenal medulla. Anatomy The locus coeruleus (LC) is located in the posterior area of the rostral pons in the lateral floor of the fourth ventricle. It is composed of mostly medium-size neurons. Melanin granules inside the neurons of the LC contribute to its blue colour. Thus, it is also known as the nucleus pigmentosus pontis, meaning "heavily pigmented nucleus of the pons." Th ...

Nissl Stain
Franz Alexander Nissl (9 September 1860, in Frankenthal – 11 August 1919, in Munich) was a German psychiatrist and medical researcher. He was a noted neuropathologist. Early life Nissl was born in Frankenthal to Theodor Nissl and Maria Haas. Theodor taught Latin in a Catholic school and wanted Franz to become a priest. However Franz entered the Ludwig Maximilian University of Munich to study medicine. Later, he specialized in Psychiatry. One of Nissl's university professors was Bernhard von Gudden. His assistant, Sigbert Josef Maria Ganser suggested that Nissl write an essay on the pathology of the cells of the cortex of the brain. When the medical faculty offered a competition for a prize in neurology in 1884, Nissl undertook the brain-cortex study. He used alcohol as a fixative and developed a staining technique that allowed the demonstration of several new nerve-cell constituents. Nissl won the prize, and wrote his doctoral dissertation on the same topic in 1885. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
