This document provides an introduction to brainwaves and brainwave entrainment. It describes the five main brainwave patterns (gamma, beta, alpha, theta, delta), their associated frequencies in Hertz, the mental and neural states and processes associated with each pattern. Each brainwave pattern is involved in different cognitive processes and states of consciousness, from high-frequency gamma waves during deep focus to low-frequency delta waves during deep sleep or meditation.

2.  Lesson Objective:
 Describe the nature and function of
brainwaves including patterns, related
processes and states.
• Gamma
• Beta
• Alpha
• Theta
• Delta

3. • The brain is powered by electromagnetic energy.
Whether we are mentally active, resting or asleep,
the brain always has electrical activity.
• We can view and analyze the traces of electrical
activity that represent the brainwaves.
• Like all waves, brain waves have a frequency,
which are measured in cycles per second or Hertz
(Hz); the lower the Hz, the slower the wave.

4. Measuring Frequency:
• Compare the two brainwave
patterns; Figures A and B.
• Pattern A is a much more rapid
pattern, with the waveform
completing its cycle 28 times in a
given timeframe.
A
• Pattern B is much slower, with
the waveform cycling only 7
times during the same time
interval.
• If the timeframe given is 1 B
second, then figure A would be
28 cycles per second, or 28 Hz.
Figure B would be 7 cycles per
second, or 7 Hz.

 Short bursts have been used to increase cognitive
functions.
