title: [Human excited electroencephalogram model and its location in brain].
abstract: The aim of this study was to identify the characteristics of human excited electroencephalogram and the excited location in brain. The subjects were excited by taking a fixed quantity of caffeine. Electroencephalographic signals were collected using with 128 channels Phoenix Digital EEG and compared before and after the subjects drank coffee. The results showed obvious differences and compared with the ones before being excited electroencephalogram. After being excited we found that the lower frequency composition was restrained in the region below 10 Hz, the high frequency composition was increased significantly,and a wave crest of 38 Hz was produced in every acquisition point with the height around 200. Then the excited region was located in brain with the software of ASA 3 Course (designed by ANT company of Germany) and found that the excited location was focused on the area of the middle abdomen in the pons' side near bulbar when a person was exciting.
