CYCLES PER SECOND (HERTZ) and Correspondences to MENTAL STATES, PHYSIOLOGY, COLORS, NOTES & PLANETS
These frequencies are of all types; light, sound, electrical, etc.
Brainwave Ranges – In talking about brainwaves, they are typically broken up into ranges, each range being associated with different mental states. The five common brainwave ranges are listed below (although I really simplify what they’re associated with here – for more specific mental states these ranges are associated with, consult the brainwave frequency list itself.)
Delta Range – 0.5 to 4 HZ (associated with deep sleep)
Theta Range – 4 HZ to 8 HZ (seen in dreaming sleep, and other mental states where the mind is wandering, like daydreaming and imagining)
"A person .. driving on a freeway & discovers .. they can’t recall the last five miles, is often in a theta state–induced by the process of freeway driving .. [It’s] .. a state where tasks become so automatic .. you can mentally disengage from them."
"[Our dominant brainwave] edges down toward theta when we go into trance."
Alpha Range – 8 to 13 HZ (relaxed but awake)
" [There is] .. more alpha wave functioning when we listen (but it edges up into beta when we do extremely active listening, as in the cocktail-party effect when we consciously narrow attention to one voice amidst a babble.)"
Beta Range – 13 HZ to 30 (??) HZ (normal awake state/aware)
There is an abundance of betawave functioning when we speak ..
Gamma Range – 30 (??) HZ to 60 (??) HZ (associated with consciousness – the brain stops producing gamma waves when we’re put under for anaesthesia, for example)
"Gamma rhythms appear to be involved in higher mental activity, including perception and consciousness. It seems to be associated with consciousness, eg it disappears with general anaesthesia .. Synchronous activity at about 40Hz appears to be involved in binding sensory inputs into the single, unitary object we perceive." [INT]
Note that there’s a LOT of disagreement over where Beta range ends and Gamma range begins. (hence the question marks)
0.1-1 Organ/muscle resonances [SS]
0.1-3 Delta range, according to [NEU+CRI] – deep sleep, lucid dreaming, increased immune functions, hypnosis [NEU]; Decreased awareness of the physical world. Access to unconscious information. Dominant brainwave in infants under one year old. This range normally decreases when we focus, but this doesn’t happen when a person with ADD – delta waves actually increase when they try and focus. [CRI]; "Monroe focus 21" [MB2 via DW];
0.16 – 10 – Neuralgias [AT]
0.18 – 10 – Mod. therapy [AT]
0.20 – 0.26 – Dental pain [AT]
0.20 – 10 – Post-traumatics [AT]
0.28 – 2.15 – Alcohol addiction [AT]
0.28 – 10 – Arthritis [AT]
0.30 – 0.15 – Depression [AT]
0.30 – 10 – Cervobrachial syndrome [AT]
0.37 – 2.15 – Drug addiction [AT]
0.40 – 10 – Confusion [AT]
0.45 – 10 – Muscle pain [AT]
Below 0.5 – Epsilon range, extraordinary states of consciousness, high states of meditation, ecstatic states of consciousness, high-level inspiration states, spiritual insight, out-of-body experiences, Yogic states of suspended animation. [CNR]
0.5 – very relaxing, against headache [MB], for lower back pain [AS] ; Thyroid, reproductive, excretory stimulant, whole brain toner [SS]
0.5-1.5 Pain relief [SS + CMP] ; endorphins, better hypnosis [SS]
0.5-3 Delta range, according to [RA]
0.5-4 Delta range, according to [SS,PWM+AWI]. Deep dreamless sleep, trance, suspended animation [SS]; Anti-aging. Reduces amount of cortisol, a hormone associated with stress & aging. Increases the levels of DHEA (anti-aging) & melatonin (decreases aging process.) [BAR]; Associated with unconscious mind & sleep state – in conjunction with other frequencies in a waking state, "Delta acts as a form of radar – seeking out information – reaching out to understand on the deepest unconscious level things that we can’t understand through thought process." Provides intuition, empathetic attunement & instinctual insight. [AWI]; Conducive to miracle type healing, divine knowledge, inner being & personal growth, rebirth, trauma recovery, "one with the universe" experiences (samadhi), near death experience, characterized by "unknowing", merely a blissful "being" state such as deep sleep or coma.
