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.
