The cerebellar vermis (Latin for worm) is located in the medial, cortico-nuclear zone of the cerebellum, residing in the posterior fossa of the cranium. The primary fissure in the vermis curves ventrolaterally to the superior surface of the cerebellum, dividing it into anterior and posterior lobes. Functionally, the vermis is associated with bodily posture and locomotion. The vermis is included within the spinocerebellum and receives somatic sensory input from the head and proximal body parts via ascending spinal pathways.
The cerebellum develops in a rostro-caudal manner, with rostral regions in the midline giving rise to the vermis, and caudal regions developing into the cerebellar hemispheres. By 4 months of prenatal development, the vermis becomes fully foliated, while development of the hemispheres lags by 30–60 days. Postnatally, proliferation and organization of the cellular components of the cerebellum continues, with completion of the foliation pattern by 7 months of life and final migration, proliferation, and arborization of cerebellar neurons by 20 months.
Vermis is the fourth full-length album by New Zealand death metal band Ulcerate. It was released on September 13, 2013 in Germany and Benelux, September 16 in the UK and internationally, and September 17 in North America. It is the first album by Ulcerate to be released through Relapse Records.
While the band has been noted for its use of dissonance, drummer Jamie Saint Merat countered that "[d]issonance for dissonance’s sake is extremely fatiguing". Given this, Merat said that Vermis uses melody in a "weird and unsettling" way to create "a tangible amount of tension and release". Merat further noted that the band made a conscious decision with Vermis to bring back "a level of unpredictability we've always had in the past" due to the feeling that the previous album, The Destroyers of All, "came out a little too fluid on the whole".
According to Merat, Vermis uses the metaphor of invertebrate animal species to explore "the over-arching theme of spinelessness [and] oppression". Merat explained that different forms of oppression are explored on the album, including:
I run my hands along the rail
Like I'm banging on a dead nail
I pull your mask around your face
And pack your castle in a big case
You're not a sage
But you know you're always on a big stage
I'm gonna live forever
I'm gonna live forever
I'm gonna live forever
I'm gonna live forever
He was just a guy with his plan
Pitchin' rubbers with his rain-tan
I took a date from the two day dance
I kissed my girl in pretty blue pants
Got to shake your hand
You know I've always been a big fan
I'm gonna live forever
I'm gonna live forever
I'm gonna live forever
I'm gonna live forever
On holiday when she was away, I was always
Never gonna, ever gonna
I'm gonna live forever
I'm gonna live forever
I'm gonna live forever
I'm gonna live forever
Stop right there, I got a dare
You pull your plan and dig your heal
Spin your castle on a bent wheel
Pull your mask around your face
And throw your hands into a big space
I'm not just gonna stand like I'm
Waiting for the big hand
