Centromedian nucleus
In the anatomy of the brain, the centromedian nucleus, also known as the centrum medianum, (CM or Cm-Pf) is a part of the intralaminar nucleus (ILN) of the thalamus. There are two centromedian nuclei arranged bilaterally.
In humans, it contains about 2000 neurons per cubic millimetre and has a volume of about 310 cubic millimetres with 664,000 neurons in total.
Input and output
It sends nerve fibres to the subthalamic nucleus and putamen. It receives nerve fibres from the cerebral cortex, vestibular nuclei, globus pallidus, superior colliculus, reticular formation, and spinothalamic tract.
Function
Its physiological role involves attention and arousal, including control of the level of cortical activity. Some frequencies of extracellular electrical stimulation of the centromedian nucleus can cause absence seizures (temporary loss of consciousness) although electrical stimulation can be of therapeutic use in intractable epilepsy and Tourette's syndrome. General anaesthetics specifically suppress activity in the ILN, including the centromedian nucleus. Complete bilateral lesions of the centromedian nucleus can lead to states normally associated with brain death such as coma, death, persistent vegetative state, forms of mutism and severe delirium. Unilateral lesions can lead to unilateral thalamic neglect.

They say: "This day will come so please don't be afraid."
But since this child's a man now,
We'll be away, away, away.
You've spent too long away, away, away.
We only sleep to pass away the days.
I've learnt to leave my body;
To find peace away, away, away.
You've gone too far away, away, away.
A childhood friend is now unknown to me.
Thieves in the stars are godlike.
While they're away, away, away.
Home, a smothered star.
The womb's way too far.
All fingerprints astray, astray, astray.
Where wide-eyed gods are thought to be unseen.
Some slip out of their conscience to find truth.
Away, away, away.
A gathered source of waves, of waves, of waves.
Abandoned body, mobility of "think".
Aesthetic proof beyond nimbus,
Come find me away, away, away.
Home, a smothered star.
The womb's too far.
Something's wrong,
It's very wrong.
It all becomes unharmed.
Seared stretch of soil and scab.
A bored time of simple man.
We need something more.
Something more.
Time stands still in children's hands.
It all changed 'cause Bruce Lee's dead.
We need something more.
Something more.
Coffee-fuelled robots with plans.
Dollars, dimes, supply and demand.
We need something more.
Something more.
Home, a smothered star.
The womb's way too far.
World way out there.
You're sort of strange.
Fruit for the brain.
Hope of true source.
But it's so far.
