occipital lobe is concerned with vision so its not that
neurotransimitter do not have anything to do with wt gain
myelin sheath deal with nerve impulse conduction....
its the temporal lobe, that deals with organising sensory information... people have temporal lobe epilepsy.
A positive emission tomography (PET) scan is used to produce a detailed, three-dimensional picture of the inside of the body. The images clearly show the part of the body that is being investigated and can also highlight how effectively certain functions of the body are working.
What are PET scans used for?
PET scans are most commonly used to help diagnose a range of different cancers and work out the best ways of treating them. The information provided by a PET scan can show how far a cancer has spread or how well it is responding to treatment.
PET scans are occasionally used to help plan complex heart surgery, such as a heart transplant. They are also used to help diagnose a number of conditions that affect the normal workings of the brain (neurological conditions), such as dementia.
