Intro to Brainwaves

I just felt like I want to talk about our brainwaves.
Brainwaves are tiny oscillated electrical voltages in the brain; each wave is just a few millionths of a volt.
Your brain is a frequency generator, every thought has a frequency and we can measure a thought , In an experiment they connected bio-feedback systems with someone's brain and they showed him a picture and measured the response of his brain to this picture, then they removed the pic and asked him to imagine the pic in his mind, when he did they found the SAME feedback from his brain as if he's seeing it.
Another experiment that they connect bio-feedback systems to athletes and asked them to run their events in their mind, Incredibly, the same muscles fired, in the same sequence as if they're really racing in the field.
So every state of mind or body has a frequency.
Scientists made lots of researches and categorized them into 4 main states (Beta, Alpha, Theta and Delta). These brainwave changes through the day and your actions.

Beta

Alertness
Concentration
Cognition

Beta waves ranges from 13-40 HZ
Beta state correlates with peak concentration, heightened alertness, eye-hand coordination and visual acuity.
When your brain is in Beta activity you're wide awake, alert. Your mind is sharp, focused.
You're able to do any work that require your full attention.
People who have ADD/ADHD are treated with stuff to move their brains to Beta state.

Alpha

The Zone
Calmness
Visualization
Creativity
Flow

Alpha waves range from between 7-12 HZ
When you're truly calm and awake then you're in "The Zone", your awareness expands and flows with creative energy.
Fear and anxieties that may existed in predominantly Beta state will dissolve into courageous clarity in Alpha state.
This brainwave states help you to tap your creativity, solve difficult problems, discover new approaches and practice creative visualization.
Alpha offers you mental clarity with the tranquility essential with your health and well-being.
In the lower range of Alpha (7-8 HZ) you can access the wealth of creativity that lies just below your conscious awareness.
The range of (7.5 - 8.5 HZ) is known as the Schumann Resonance which is the resonant frequency of the earth's electromagnetic field.
When your brain resonates with at this point you've placed your mind in true harmony with life.
This state also known as Super Learning and creative problem solving state.

Theta

Deep Meditation
Intuition
Memory
Mysticism
Hallucinating, Dreaming

Theta waves range between (4 - 8 HZ).
Theta is the realm of the smoldering subconscious and the semi-conscious gateway to the mysterious unconscious.
It is the state we're in while dreaming and right as we awaken from a dream.
It is full of vivid imagery, rejected psychic material, flashes of insight and inspiration of genius.
Also Theta has been identified as the area of long-term learning and memory. Theta meditation enhances learning capacity, reduces stress and awaken intuition and other extra sensory perception skills (we'll talk about the ESP later).
A deep meditation in Theta brings you inspiration, long forgotten memories, flashes of dreamlike imagery and heightened receptivity.
Theta sits in the threshold of your subconscious/unconscious mind.
Brainwaves in this range engage the places where you hold memories and underlying emotions, we can store secrets which feel unprepared to fix, in this subconscious/unconscious realm.
Theta is ideal for super-learning, reprogramming your subconscious mind, dream recollection and hypnosis.
Drugs and Alcohol may drive your mind to Theta brainwave but due to their destructive effects on health and mind, we use audio brainwave entertainment to reach this state.

Delta

Healing
Deep Sleep
Detached Awareness

Delta waves range from (0-4 HZ)
These are long, slow, rising and falling waveforms.
Delta is the slowest of all four brainwave freq ranges.
It's associated with deep sleep, and certain frequencies in the Delta range trigger the release of Human Growth Hormone, which can be beneficial for healing and regeneration.
This is why deep sleep is essential to the physical healing process.
Delta is the brainwave signal of the unconscious. if you want to access your unconscious activity you may need to meditate so deeply.

Next time I'll write about the special state (Alpha) and why it is so special
