Recent research conducted at the Massachusetts Institute of Technology (MIT) suggest that scientists have cleared Alzheimer causing plaques from the brains of Mice using light and sound .
“This noninvasive treatment, which works by inducing brain waves known as gamma oscillations, also greatly reduced the number of amyloid plaques found in the brains of these mice.”
“In 2016 the researchers used light flickering at 40 hertz, delivered for one hour a day .”
“In their new study, the researchers set out to explore whether they could reach other brain regions, such as those needed for learning and memory, using sound stimuli. They found that exposure to one hour of 40-hertz tones per day, for seven days, dramatically reduced the amount of beta amyloid in the auditory cortex (which processes sound) as well as the hippocampus, a key memory site that is located near the auditory cortex.”
40hz – The Magic Number
So it appears that a 40hz tone or a 40hz flickering light can induce a gamma brain wave also at 40hz .
In case you were wondering what gamma waves are :
These are involved in higher processing tasks as well as cognitive functioning. Gamma waves are important for learning, memory and information processing. It is thought that the 40 Hz gamma wave is important for the binding of our senses in regards to perception and are involved in learning new material. It has been found that individuals who are mentally challenged and have learning disabilities tend to have lower gamma activity than average.
- Frequency range: 40 Hz to 100 Hz (Highest)
- Too much: Anxiety, high arousal, stress
- Too little: ADHD, depression, learning disabilities
- Optimal: Binding senses, cognition, information processing, learning, perception, REM sleep
- Increase gamma waves: Meditation
In fact gamma waves would appear to underpin many important neural processes .
“Many neuroscientists hold an almost mystical reverence for gamma oscillations due to their associations with working memory, cognition, attention, and even consciousness itself.”
It is thought that neural oscillations may connect clusters of neurons and also different areas of the brain .
From Wikipedia :
“Neural oscillations are thought to play a key role in processing neural information .”
“Neural oscillations are observed throughout the central nervous system at all levels .”
“Synchronization of neuronal firing may serve as a means to group spatially segregated neurons that respond to the same stimulus .”
“The functional role of synchronized oscillatory activity in the brain was mainly established in experiments performed on awake kittens with multiple electrodes implanted in the visual cortex .”
“These experiments showed that groups of spatially segregated neurons engage in synchronous oscillatory activity when activated by visual stimuli .”
“The frequency of these oscillations was in the range of 40 Hz .”
Neural oscillation appears to be crucial to associative learning .
“Associative learning requires mapping between complex stimuli and behavioural responses. When multiple stimuli are involved, conditional associative learning is a gradual process with learning based on trial and error. It is established that a distributed network of regions track associative learning, however the role of neural oscillations in human learning remains less clear.”
“Learning is a dynamic process where neural representations are refined and change with experience. Our results highlight a central role of frontal theta and posterior alpha/beta oscillations in forming new associative memories .”
Gamma band brain waves are also important for associative learning .
Hippocampal gamma waves are said to be critical to associative learning and further memory encoding .
“The hippocampus is critical to forming novel associations between previously unrelated items , binding information across time and space. Prior studies investigating the neural basis for successful episodic learning have described gamma (40–100 Hz) increases with simultaneous decreases in theta (5–8 Hz) in the hippocampus and widespread cortical regions during successful encoding, distinguishing items that are later successfully remembered versus forgotten, termed the subsequent memory effect .”
Gamma oscillations are closely connected with the visual cortex .
“Using human ECoG, we observed that some stimuli (gratings and some natural images) elicit robust gamma oscillations (30–80Hz) in visual cortex, manifest as a 10-fold elevation in power. In the same subjects and with the same recording apparatus, we observed that gamma oscillations evoked by other stimuli (noise patterns and some natural images) were indistinguishable from baseline.”
Very closely connected .
“A striking feature of some field potential recordings in visual cortex
is a rhythmic oscillation within the gamma band (30–80 Hz). These oscillations have been proposed to underlie computations in perception, attention, and information transmission .”
Lasers have been used to induce gamma oscillations in the mammalian brain .
“Scientists have studied high-frequency brain waves, known as gamma oscillations, for more than 50 years, believing them crucial to consciousness, attention, learning and memory. Now, for the first time, MIT researchers and colleagues have found a way to induce these waves by shining laser light directly onto the brains of mice.”
The optogenetic approach often involves an electrode array implant with integrated optical fibre .
“Transient gamma-band (40–80 Hz) spatiotemporal patterns are hypothesized to play important roles in cortical function. Here we report the direct observation of gamma oscillations as spatiotemporal waves induced by targeted optogenetic stimulation”
Being ‘zapped‘ with a 40hz electric current was found to induce 40hz gamma wave neural activity in the human brain .
“The sweet spot was 40 Hertz. Zapping sleeping volunteers at this frequency, part of the so-called gamma wave band, led their brains to produce brain waves of the same frequency, the researchers found, which triggered lucidity 77 percent of the time, as determined by self-reports from the dreamers after they were awoken.“
In case you were wondering what a 40hz tone sounds like :
In case you were wondering why this could be significant :
- Home Who is behind this project? World Hum Map and Database Project
- What is the mysterious ‘global Hum’ – and is it simply noise pollution?
Long term meditation is said to increase gamma wave synchronicity in the brain .
“Here we find that long-term Buddhist practitioners self-induce sustained electroencephalographic high-amplitude gamma-band oscillations and phase-synchrony during meditation.”
Meditation is said to be the secret of mindfulness .
“Matthieu Ricard, a 66-year old Tibetan monk and geneticist, produces brain gamma waves—linked to consciousness, attention, learning and memory—never before reported in neuroscience, leading researchers to conclude that Ricard is the world’s happiest man. The secret to his success in achieving bliss? Meditation, he claims.”
If it is possible to induce a particular brain state with light or sound , is it also possible to use other electromagnetic frequencies to entrain the brain ? (I’m a poet , but I don’t like to bestow it (on anybody else)) .
Undoubtedly yes .
Considering that gamma oscillations are connected to the visual cortex and the dream state , could subliminal imaging be induced in the human brain ?
Perhaps imaging designed to produce a particular state of mind ?
Or maybe imaging designed to produce a particular subconscious state of mind ?
Perhaps a subconscious state of mind which could also maifest itself in a persons conscious life ?
A stimulation simulation perhaps ?
