Keyword: EEG
EEG - an electroencephalogram is a test to record electrical activity (since neurons communicate through electrical impulses) in the brain. Small metal discs, electrodes, are placed on the scalp and send signals to a computer nearby. Typical electrical activity in the brain makes a recognizable pattern, so by studying the patterns detected, we can identify any abnormal activity. We can also study how the brain responds to external stimuli, such as sounds. While it lacks some of the detail of other imaging techniques such as MRI, it remains very valuable as it’s very mobile and can detect changes over time down to a millisecond-range. The equipment is also silent (unlike, say, MRI) and the hardware is much less expensive than other approaches. It is used extensively in research.
