Understanding Brain Waves: Frequencies and Behaviors

 
What is a Brain Wave?
 
Wave Review
 
Waves carry energy through space
Examples
 of waves:
Ocean waves
Sound waves
Light waves
Waves may be characterized by their 
frequencies
How many full waves occur per second

More on Frequency
 
Higher
 frequencies result in 
more energy
 being transferred over time
Lower frequencies 
result in 
less energy 
being transferred over time
Example
: electromagnetic (EM) waves
EM waves with higher frequencies (UV, x-ray, gamma) carry more energy, and can harm
us if we are exposed to them for long periods of time
EM waves with lower frequencies (radio, infrared, light) carry less energy, and are safe for
human contact
 
Example: Electromagnetic Spectrum
 
How do our 
brains
 use energy?
 
Our nervous system also uses waves to transfer energy throughout the
body
We call these 
brain waves
Brain waves are classified by their 
frequencies
, and each type is
associated with a different level of human behavior
 
Types of Brain Waves: Delta
 
Delta waves
 are brain waves with frequencies between ~0.2 Hz – 3 Hz
These waves are associated with a 
deep, restful state
Example of associated behavior: 
deep sleep
 
Types of Brain Waves: Theta
 
Theta waves 
are brain waves with frequencies between ~4 Hz – 8 Hz
These waves are associated with a 
deeply relaxed, meditative state
Examples of associated behavior: 
napping/light sleep, deep meditation
 
Types of Brain Waves: Alpha
 
Alpha waves
 are brain waves with frequencies between ~9 Hz – 13 Hz
These waves are associated with a 
calm, lucid state
Examples of associated behaviors: 
light meditation, daze/daydreaming
 
Types of Brain Waves: Beta
 
Beta waves
 are brain waves with frequencies between ~14 Hz – 30 Hz
These waves are associated with a 
normal, awake state
Examples of associated behaviors: 
working, actively listening, reading
 
Types of Brain Waves: Gamma
 
Gamma waves
 are brain waves with frequencies greater than 30 Hz
These waves are associated with a 
concentrated state
Examples of associated behaviors: 
intense focus, working on a difficult problem

Brain waves are electromagnetic signals produced by the brain, categorized by frequencies into Delta, Theta, Alpha, and Beta waves, each associated with different states of consciousness and behaviors. These waves play a crucial role in our brain's energy utilization and overall functioning.
