Promoting Gamma Wave Production with Meditation They concluded that this prolonged use of BWE to stimulate gamma brainwaves could act as an effective treatment for Alzheimer’s.Įven though the methods of stimulating gamma brainwaves to treat serious diseases like Alzheimer’s are still in the developing stages, scientists and researchers have proven that increasing gamma brainwaves helps individuals with their emotional states and their cognitive abilities. In response, scientists increased the mice’s exposure to the LED lights over a week and noticed that both amyloid plaques and traces of the amyloid protein decreased drastically. They found that the amyloid plaque was reduced by nearly half, though the results were short lived – they were only present over a 24 hour period. In one experiment on mice, researchers used exposure to LED lights (a form of brainwave entrainment) to facilitate gamma brain waves. Though it is not completely understood, gamma waves seem to be able to activate the immune system to attack plaques on its own. These plaques are dangerous and can quickly advance the symptoms of the disease. Gamma Waves & Preventing Alzheimer’s DiseaseĪlzheimer’s Disease results after a protein (beta-amyloid) builds up like a plaque between neurons. Researchers in this experiment backed up the previously mentioned theory that asserted that attention activities (such as meditation) activated gamma brainwave activity in individuals, confirming meditation’s positive influence. Many in the science community suggest that gamma activity also dictates a lot about memory- but primarily short and long term. Other studies have shown that gamma brainwaves are also closely associated with data processing and attention, because gamma frequencies are linked to the sensory process. Researchers found that those whose brains emitted gamma waves early in the experiment were better at both handling their emotions and refocusing their minds. They then categorized the types of waves they observed and related them to each subject’s ability to regulate both their attention and emotions. They recorded an electroencephalogram (EEG) of 15 different subjects who then experienced a variety of emotions. Researchers conducted a study to monitor the role of gamma brainwaves in situations that evoked emotional response. Controlling cognition is a valuable practice that individuals can use to maintain emotional stability. Nobel prize winning scientist, Sir Francis Crick believes that the 40 Hz frequency may be the key to the act of cognition. It is also said that those with high gamma brain wave activity have the highest IQ scores and are often high academic achievers, athletes and also talented musicians. Gamma are also the highest frequency waves with the smallest amplitude, and are associated with feelings of satisfaction as well as improved cognitive functioning- think memory retention, data processing and basic focus.īecause gamma waves are so high frequency, the quick motion creates a sweep of the brain that helps link information and improve cognition. Gamma brain waves have a frequency anywhere from 25 Hz to 100 Hz, though 40 Hz is typical and of considerable importance in brainwave entrainment, as we'll get to later. Very little was known about the mysterious nature of brainwaves until the mid 1960s, which is when scientists began to develop and use digital electroencephalogy, a tool that helped researchers record and measure the rhythms of the brain. These brain waves have varying frequencies based on the state of the individual. The cumulative nature of this activity is what is defined as a brain wave. The brain is comprised of billions of cells called neurons that communicate with other neurons via electrical signals. Judging by the litany of jokes about becoming a neurosurgeon, most people accept that the brain is dizzyingly complex, so it is helpful to understand the brain’s basic processing method a little more fully to grasp the significance of brain waves. The importance of brainwaves are of paramount interest in this field of study. Though the inner workings of the mind are both widely researched and speculated on, information about how the brain functions and how it affects emotions is ongoing.
