Study Notes
Brain Waves Overview
- Alpha waves: Low-amplitude, slow, synchronous waves indicating a calm state.
- Characteristic of an awake but relaxed brain; often referred to as an idling brain.
Beta Waves
- Rhythmic and more irregular in nature.
- Associated with an awake and alert mental state, indicating active cognitive processes.
Theta Waves
- More irregular compared to alpha waves; suggestive of light sleep or relaxation.
- Common in children; presence in adults may indicate abnormal brain function.
Delta Waves
- High amplitude waves occur when the reticular activating system is damped, signifying deep sleep.
Measurement of Brain Waves
- Brain waves are measured using an electroencephalogram (EEG), a key tool for analyzing electrical activity in the brain.
Factors Affecting Brain Waves
- Brain wave patterns can change due to age, sensory stimuli, brain diseases, and the chemical state of the body.
