What is "neuraxis"

Neuraxis \Neu*rax"is\, n. [Neuro- + axis.] (Anat.) See Axis cylinder, under Axis.

n. (context anatomy English) The axis of the central nervous system; i.e. the spinal cord, rhombencephalon, mesencephalon and diencephalon.

Neuraxis is a Canadian technical death metal band formed in Montreal in 1994 by Steven Henry, Yan Thiel, Michel Brisebois and Felipe Ángel Quinzanos. They have released six studio albums: Imagery (1997), A Passage into Forlorn (2001), Truth Beyond... (2002), Trilateral Progression (2005), The Thin Line Between (2008), and Asylon (2011).

In 2007, the band participated in the Domination Tour alongside Rotting Christ, Incantation and Malevolent Creation. After touring, the band released a live album entitled Live Progression. Neuraxis participated in the Montreal Assault Tour with Despised Icon, Beneath the Massacre, Carnifex and Plasmarifle to promote their album The Thin Line Between.

The band released their sixth studio album, Asylon, on February 15, 2011.

The neuraxis or sometimes neuroaxis is the axis of the central nervous system. It denotes the direction in which the central nervous system lies. During embryological development, the neuraxis is bent by various flexures, contributing to the mature structure of the brain and spinal cord.

Embryonic development can help in understanding the structure of the adult brain because it establishes a framework on which more complex structures can be built. First, the neural tube establishes the anterior–posterior dimension of the nervous system, which is called the neuraxis. The embryonic nervous system in mammals can be said to have a standard arrangement. Humans (and other primates, to some degree) make this complicated by standing up and walking on two legs. The anterior–posterior dimension of the neuraxis overlays the superior–inferior dimension of the body. However, there is a major curve between the brain stem and forebrain, which is called the cephalic flexure. Because of this, the neuraxis starts in an inferior position—the end of the spinal cord—and ends in an anterior position, the front of the cerebrum. This may be confusing, and can be illustrated when looking at a four-legged animal standing up on two legs. Without the flexure in the brain stem, and at the top of the neck, that animal would be looking straight up instead of straight in front.
