Neuroimaging includes the use of various techniques to either directly or indirectly image the structure, function/pharmacology of the brain. It is a relatively new discipline within medicine and neuroscience/psychology. Physicians who specialize in the performance and interpretation of neuroimaging in the clinical setting are neuroradiologists.
Neuroimaging falls into two broad categories:
Functional imaging enables, for example, the processing of information by centers in the brain to be visualized directly. Such processing causes the involved area of the brain to increase metabolism and "light up" on the scan. One of the more controversial uses of neuroimaging has been research into "Thought identification" or mind-reading.
In 1918 the American neurosurgeon Walter Dandy introduced the technique of ventriculography. X-ray images of the ventricular system within the brain were obtained by injection of filtered air directly into one or both lateral ventricles of the brain. Dandy also observed that air introduced into the subarachnoid space via lumbar spinal puncture could enter the cerebral ventricles and also demonstrate the cerebrospinal fluid compartments around the base of the brain and over its surface. This technique was called pneumoencephalography.
No sun for the grey children
Waiting to catch the strange
Airy notions of that place
Now they evolutions
Means their brain mutations
The wider is the comprehension
The deeper and stronger is the illusion
They're no more material
Since they're invisible
High pressure inside me
Erasure, I'm empty
With their talk, they fill me
Now I walk, so brainy
Who's in my head, hiding themselves
It hurts me so, it's a brainscan
Who's it instead, instead myself
I hate it so, it's a brain scan
Creeping in your double mind
There's nothing they can't find
You've lost all your energy
Not able to set you free
They will own you just like me
Just like me, just like me...
High pressure inside me
Erasure, I'm empty
With their talk, they fill me
Now I walk, so brainy
Some times I feel
Their cold presence
Checking my mind, it's a brain scan
Sometimes my soul
Can't reach a sense
This head is mine, it's a brain scan
Don't ask'em to give a break
You can't even close the gate
Passing through both hemispheres
Searching in all memories
Knowing what's inside of me
Side of me, side of me....
Perceptive entity
Emotive synergy
Hyper-detection
Suck out the reason
Is there something I could feel
Translucid language
Reflect the new age
Words are a limitation
Locking me out of my skull
Something without physical
Disturbing my frequency
Terminate identity
