Types Of Brainwaves
- Beta waves (15 to 40 cycles per second) are generated during a highly engaged or aroused state of mind, like talking, debating or making a speech.
- Alpha waves (a frequency of 9 to 14 cycles per second) are slower, with the brain in rest mode, happening when a person is reflecting, sitting down and resting, or walking in the park.
- The Theta waves are generated during an even slower state of mind (5 to 8 cycles per second) usually when a person is daydreaming or is on a long freeway drive.
- Delta waves (1.5 to 4 cycles per second) are the slowest, happening when we are in deep sleep.

The 90 Minute Dream Cycle
One dream cycle is usually 90 minutes, where delta waves slowly increase frequency to morph into theta waves, which is the REM state of dreams. The awakening cycle in the morning, when the transition takes place from theta to alpha and finally beta (when we hit the snooze button!)

Eureka Moments In Theta And Alpha States
Many people in the ‘theta’ state happen to get good ideas, as do people who are mentally relaxed due to being in the alpha state.
The repetitive task becomes automatic and disengages itself from the mind, leading to a free flow of ideas.

Our Brainwaves
The human brain is a highly complex electrochemical organ, generating as much as 10 watts of electricity.
This electrical activity is displayed in the form of four types of brainwaves: Beta, Alpha, Theta and Delta which correspond with focus, rest, creativity...

5 Categories of Brain Waves
- Gamma State: (30 - 100Hz) The state of hyperactivity and active learning.
- Beta State: (13 - 30Hz) It is associated with the alert mind state where we function for most of the day.
- Alpha State: (9 - 13Hz) Brain waves start to slow down out of thinking min...
Different types of brain waves
Specific frequencies are thought to be involved in specific cognitive tasks.
- During deep sleep, the predominant brain activity occurs with frequencies between 1 and 4 Hertz (delta waves.) Delta waves are associated with learning and motivation.

Stages 1 To 4
- When people are relaxed and ready to fall asleep, their EEG will show mostly alpha waves. When people fall asleep, they enter into stage 1 sleep, which lasts just a few minutes. In stage 1, the EEG shows mostly theta waves. Heart rate, breathing rate, and body temperature drop, and muscles r...
