EEG brain image during mobile phone research
Mobile telephone research. Electroencephalogram (EEG) maps of a person's brain normally (upper frame) and when they have a mobile telephone by their left ear (lower frame). Cancer and changes in the levels of hormones may be caused by the effect of microwaves absorbed in the telephone user's head. The EEGs show the electrical activity in the brain,measured in microvolts-squared. The 2 EEGs at left show the total activity. The activ- ity is colour-coded from red (high) through yellow to blue (low). The position of the electrodes measuring the activity are shown as a code,such as "C3". At right is a table which shows the difference in readings from pairs of electrodes
