  Brain Imaging
The practice of brain imaging is improving steadily thanks to the rapidly advancing technologies available to today’s neuroscientists and to the field of medicine in general.
Brain imaging allows for a glimpse into the internal functions, properties and capacities of the living brain, all of which could only be assumed or hypothesized until the last few decades.
Another advantage is the capacity to determine which areas are adversely influenced by brain disorders, thus providing doctors with the relevant information needed to properly and effectively treat the disorders.

Brain Imaging Studies Investigate Pain Reduction By Hypnosis
Processing of the pain signal through the lower parts of the pain network looked the same in the brain images for both hypnotized and non-hypnotized trials, but activity in the top level of the network, which would be responsible for "feeling" the pain, was reduced under hypnosis.
Electroencephalography -- Electroencephalography is the neurophysiologic measurement of the electrical activity of the brain by recording from electrodes placed on the scalp or, in special cases, on the cortex.

The positron emitting radioisotopes used are produced by a cyclotron and chemicals are labelled with these radioactive atoms.
Functional MRI (fMRI) relies on the paramagnetic properties of oxygenated and deoxygenated hemoglobin to see images of changing blood flow in the brain associated with neural activity.
PET, however, retains the significant advantage of being able to identify specific brain receptors associated with particular neurotransmitters through its ability to image radiolabelled receptor ligands.
