The examination is reflected in the form of graphic curves on computer screen or as a record. After the examination, the physician shall analyse the record of the electroencephalogram.
Usually, during the examination, the specialist asks the patient to relax in the chair. Registering electrodes are attached to the head of the patient. After the initial registration of brain activity, the examination is performed with various stimuli, for instance, the specialist may ask the patient to breathe deep and fast for three minutes. Stimulation can also be performed with a bright light, etc.
