One of the defining properties of a neurotransmitter is that is must be synthesized in the neuron. The brain does not synthesize methamphetamine. Methamphetamine is introduced exogenously and exerts its effects on a neurotranmitter system called the 'adrenergic system'. Methamphetamine also has a direct effect on dopamine transmission. The drug, like its parent structure (amphetamine) causes a release of dopamine through reuptake transporters (DATs), which have been modulated to reverse their normal function as a consequence of binding this drug. This rush of dopamine is what gives rise to many of the euphoric (hedonic) as well as addictive properties of this drug. So infact it is acting as an indirect neurotransmitter, but is not an endogenous (normally produced and supplied in the body) molecule.
Dopamine is the pleasure-producing neurotransmitter in the brain.

The dorsal cavity of the body contains the brain and spinal cord, which are considered the Central Nervous System. The same neurons that make up the brain also make up the spinal cord. The only difference is that the neurons in the brain :like a pony tail of hair" only differentiate as a result of their job; as a transmitter or a receptor,

You are said to be brain dead and are not vaible.
NO! Only the spinal column, which is an extension of the brain, but not considered part of the brain.
No definitive and unequivocal evidence has been produced to prove either that that the radiation from mobile phones causes any measurable damage or to prove that it does not. There have been some studies that indicate cell phone radiation may cause alteration to brain tissue, but they have not been conclusive. However, a cell phone is a powerful radio transmitter and radio wave intensity increases at the square of the distance as you approach the transmitter, so holding the transmitter against your head exposes you to the strongest radiation.
Acquired brain injury (ABI) is characterised as a brain injury which has occurred after birth, and is not the cause of any genetic or congenital disorder. A "mild" ABI could be considered as a brain injury which does not have a profound impact on the brain functioning or the sufferers behaviour, or could be considered as temporary.

The range of dopamine in the brain that is considered 'normal' is from 70mcg to 350mcg.
