The white matter can be considered the part of the brain that connects all parts with each other. Alpha is a common state for the brain and occurs whenever a person is alert it is a marker for alertness and sleep , but not actively processing information. They are strongest over the occipital back of the head cortex and also over frontal cortex. Alpha has been linked to extroversion introverts show less , creativity creative subjects show alpha when listening and coming to a solution for creative problems , and mental work.
When your alpha is within normal ranges we tend to also experience good moods, see the world truthfully, and have a sense of calmness. You can increase alpha by closing your eyes or deep breathing or decrease alpha by thinking or calculating. Alpha-Theta training can create an increase in sensation, abstract thinking and self-control. In our car scenario, Alpha would represent neutral or idle. Alpha allows us to shift easily from one task to another. It has a frequency of 14 and greater Hz.
It reflects desynchronized active brain tissue. It is usually seen on both sides in symmetrical distribution and is most evident frontally. It may be absent or reduced in areas of cortical damage. It is generally regarded as a normal rhythm and is the dominant rhythm in those who are alert or anxious or who have their eyes open. It is the state that most of brain is in when we have our eyes open and are listening and thinking during analytical problem solving, judgment, decision making, processing information about the world around us.
Beta would represent overdrive or hyperdrive in our car scenario. The beta band has a relatively large range, and has been divided into low, midrange and high. May be focused on one electrode. Effects of Training: can induce alertness, but may also produce agitation.
Gamma is measured between 30 and 44 Hz and is the only frequency group found in every part of the brain. Some scientists claim that human tissue, including the brain, may be affected nonthermally. Regrettably, many exposure parameters, such as frequency, orientation, modulation, power density and duration, make it difficult to directly compare experiments and draw specific conclusions at nonthermal levels.
Also, it is important to remember that, perhaps expectedly, interpretations of findings in this area of investigation are shrouded in controversy, particularly because special interests may influence some of the research. The publication of findings does not necessarily scientifically validate a study. At lower levels of exposure, evidence for specific effects that may occur as a result of direct neural interactions with radio frequency fields is sparse.
In addition, many of the studies that claim provocative results have yet to be replicated by independent laboratories. Other studies describe potential associations. For example, a recent report suggests that the low-intensity electromagnetic field of geomagnetic storms--disturbances in the earths magnetic field caused by gusts of solar wind--may have a subtle but measurable influence on suicide incidence in women.
In recent years, cell phones, which transmit and receive at radio frequencies, have become ubiquitous. Researchers have investigated whether these low-intensity radio waves influence the central nervous system and cognitive performance.
A few studies concluded that cell phone exposure enhanced certain aspects of cognitive performance as measured by reaction time and accuracy; others showed no difference, and a few, including a very recent investigation, showed that such exposure had detrimental effects in specific contexts such as attention span.
Replication of either the negative or positive effects of exposure on cognition is sorely lacking in the scientific literature and more work is required to verify and reconcile differences between studies reporting either contradictory or no effects. Unfortunately, at least some of these studies fail to meet many of the criteria for good research, thus weakening their scientific value further. Therefore, more well-controlled studies are required to validate conclusions as to whether exposure to cell phones influences cognition, especially in the long term.
Nevertheless, most of the reported effects are small as long as the radiation intensity is within the reasonable nonthermal range and its duration does not exceed common exposure for users. A review of 22 studies found a significant link between more prolonged exposure to binaural beat tapes and reduced anxiety. It also found that practitioners did not need to mask the beats with white noise for the treatment to have an effect.
Some researchers have even suggested that 10 minutes of exposure to a 6 Hz frequency could induce a brain state similar to that during meditation. Although there is little evidence of any adverse side effects of using binaural beat therapy, a literature review of studies identified conflicting data, so further research is necessary.
As with any self-help tool, it is important for a person to speak with a healthcare professional to determine whether binaural beats therapy is right for them. The quality of the available research is mixed. Many of the studies confirming the benefits of binaural beats therapy involved small cohorts and used subjective measurements, such as questionnaires. There are few recent, high quality studies supporting binary beat therapy as an effective treatment for anxiety. However, people can practice binary beat therapy at home with no training.
Therefore, those who find that it reduces their anxiety can use it to support ongoing anxiety treatment. It is important to note that there is a lack of research on the long term side effects of the therapy.
People may wish to start with shorter sessions of binaural beat therapy and increase their exposure gradually. Aromatherapy is a type of alternative medicine that uses essential oils to improve a person's health or mood. Find out about the oils and how they…. Acupuncture is an alternative therapy that involves inserting thin needles into targeted areas of the body. Anxiety is a common problem, but what causes it, and how can we manage it?
Here, find some practical tips for managing and treating anxiety. Melatonin is a hormone that helps to regulate daily body rhythms. EEG monitoring of Alfred Einstein showed he produced consistent alpha-band activity while solving complex mathematical tasks. Studies suggest that while upper or mid-range alpha may assist with these kinds of activities, its lower range may be counterproductive for highly attentive, focused critical thinking or technical, detail orientated work.
Alpha stimulation has a long and successful history of clinical applications for stress, anxiety, drug and alcohol addiction, depression, ADHD, autism, PTSD thought to block alpha activity , peak performance and headache relief.
At, or close to Alpha frequencies also have a long association in sports psychology and personal development for enhanced visualisation, meditation, internal goal setting processes and 'flow states'. As a point of interest, sports professionals have been observed producing a surge of alpha in their left hemisphere just prior to a successful move or strategy - and a corresponding surge of beta when they fail.
Likewise, Einstein was also observed to drop out of alpha-band activity into beta whenever he realised an error in his calculations. Alpha stimulation has also been shown to assist with emotional stability, reductions in cortisol a major stress hormone , serotonin production and significant improvements in heart rate variability HRV.
Alpha frequencies are included in nearly all SmartSound protocols. Memory consolidation; creativity, imagery and visualization; free-flowing lucid thought; spatial navigation tasks; inspiration and intuition; REM; processing of new episodic information; emotional processing and heightened suggestibility. Theta production begins at around 2 years of age. These sleep inducing, low-frequency brainwaves have been associated with deep relaxation, creativity, memory consolidation, emotional processing, vivid imagery, extrasensory perception, intuitive insights, REM states and a great deal of other subconscious activity and phenomena.
Hypnotherapists in particular, consider theta - which is associated with the highly suggestible 'hypnagogic trance' - to be the optimal state for accessing the right hemisphere and changing unwanted subconscious behaviours and programs, the reception of information beyond normal waking consciousness, and the gateway for learning and memory. Deeply suppressed emotional material and childhood memories appear to be most readily accessed and released in theta, under expert guidance.
Dominant in very deep meditation, prayer, hypnotic trance and REM states, theta is also associated with enhanced immune function and neurochemicals including vasopressin and catecholamine. Nonetheless, it's perfectly normal in young children from where it facilitates their rapid learning abilities and vivid, creative imaginations.
It's during their highly suggestible 'theta years' that a child's fundamental, life-shaping beliefs, experiences and assumptions about the world are 'programmed' into their subconscious.
