How EEG Works: A Quick Overview
Understanding the Mechanics
EEG works by placing electrodes on the scalp to measure electrical activity generated by neurons. These readings are then transformed into waveforms that scientists analyze to understand brain function. EEG is especially useful for detecting abnormalities in brain activity, such as seizures and other neurological conditions.
Types of Brain Waves
EEG measures several types of brain waves, categorized based on their frequency:
- Delta Waves (0.5–4 Hz): Associated with deep sleep.
- Theta Waves (4–8 Hz): Linked to creativity and relaxation.
- Alpha Waves (8–12 Hz): Present during states of calmness but alertness.
- Beta Waves (12–30 Hz): Associated with active thinking and problem-solving.
- Gamma Waves (30+ Hz): Involved in processing light stimuli and consciousness.
Chart: Brain Waves and Their Functions
| Frequency (Hz) | Wave Type | Associated Functions |
|---|---|---|
| 0.5–4 | Delta | Deep sleep, restorative processes |
| 4–8 | Theta | Creativity, meditation, relaxation |
| 8–12 | Alpha | Calm, alert cognitive function |
| 12–30 | Beta | Active thinking, focus, problem-solving |
| 30+ | Gamma | High-level information processing |
