The Measurement of Brain Waves
This is a device that was designed to compare the various EEG frequencies the amplitude of alpha waves and simultaneously increase the beta waves. A different age dynamics is seen for frequency of alpha rhythms. to 83%) but there was no evidence of a genetic correlation between alpha peak frequency and any because high amplitude alpha rhythms can be considered as the result of. Four simple periodic rhythms recorded in the EEG are alpha, beta, delta, and theta. These rhythms are identified by frequency (Hz or cycles/sec) and amplitude .
Goal of the project: In this project you will record the EEG with your eyes closed and in a state of relaxation and compare the records with the EEG when your eyes are open and attentive, when your eyes are closed and you are hyperventilating. You will also compare the EEG records when your eyes are open and attentive to when you are computing a mathematical problem.
You will work in pairs. One partner will have electrodes placed on their heads according the pattern illustrated in the diagram you will be given. The other partner will be the recorder.
The first task is to calibrate the equipment by selecting the calibrate button. After calibration, there will be four 30 second recording sessions divided into two 15 second components. The first component of the recording session will always be the same. Subjects will lie quietly with their eyes closed and relaxing as much as possible.
After 15 seconds of recording the recorder will instruct to subject to do the following. Keep your eyes closed and continue to relax but breathe very deeply. Instruct the subject to take the number 2 and double it, double again, double again, divide by three, multiply by 15, divide by seven, multiply by twelve. Instructions to the Recorder: But this is why most meditating people have serious problems with meditation. Meditation itself as a state of mind, according to e.

And can we use these waves in our daily life to stimulate our brain or to increase limits of our brain? Lee December 23,4: Ophelia December 21,1: Abdu January 8,5: Reply Link Cindy September 18,1: I sleep with it every night.
I was starting to become suicidal. I have a long history of depression and ADHD, so nothing seemed out of the ordinary.
It started to become worse. Then I switched to gamma, I kept getting sick, as in dizzy spells. I would start vomiting if I listen to gamma. Question is, is this at all normal? If not why is this happening?
Changes in EEG amplitude (Alpha and Beta waves) with Thermal environment
Reply Link Liina January 15,2: I would think that DELTA waves are the important ones during sleep, as this state is the rejuvenating, restorative one, where your body regenerates. I have had sleeping problems myself, and have realised that listening to anything while sleeping makes me feel worse. I use silicone earplugs to block out noise, and a black fabric over my eyes to block out all light, and listen to something very relaxing on Youtube BEFORE going to sleep.
You could try ASMR videos, they often make people sleepy… or some sleep meditation videos. And remember to get at least some light exercise whenever you can, it makes you more sleepy and lifts the mood cliche but true.
And maybe check with your doctor as well. All the best, take care. Liina xx Just to clarify: Reply Link Lucinda June 15,6: Cindy, what I did was exercise at least 1 hour walking, weight lifting, swim then listen to these waves before I went to sleep until I become really tired then shut it off. Mostly importantly, stay off caffeine and alcohol!!! Switch to decaf teas and homemade smoothies. Force it first thing in the morning. Also, research foods and vitamins that lift and promote good moods.
Stay away from people that cause you to feel down. Reply Link Robert August 23,3: I think the brain waves you listen to are going to dramatically affect you the following day. I think much more so than light sleeping pills.
The reason I believe is that the brain waves you expose yourself to at night are going to process in your subconscious and become prevalent in you following day. I believe the sleep we receive essentially primes us for the following day. I believe the excess Theta or Theta dominant brain waves are causing your excess depression.
I imagine they are causing your next day reality to be very gloomy and withdrawn. As for the Gamma brain waves, they may not have a direct, stable and well understood function such as a low beta brain wave for example. Although there are speculations and possible explanations for gamma brain waves, I believe it is possible that they may have a unique and special purpose of their own, but not the type to be specified as a major brain wave to be trained upon yourself.
I would recommend not going so intense with any brain wave training, as it may interfere with who you naturally are. Let me explain my summary of what that may be in my assessment: Delta Be careful, if that affects your day you much, you may feel like a sluggish and even like a non-functional vegetable. In a sense it could be likened to seeing the world from beneath the water.
Everything in the world may not seem bright and happy for what it is. Alpha Alpha may be like a bridge between the inner world and lower brain waves and the faster brain waves externally engaging the world and action.
They may allow one to process the movements and energies of the external world by not being so in motion and busy oneself and the Alpha waves may also be in a position to contemplate deeper thoughts and other alternatives that would require teaming up Theta waves with Beta waves for example.
Again, our brains use a lot of waves and like a manual transmission car our brains probably select what they need. Beta More activity, more action, more running yourself at high speeds. With all the waves keep in mind the brain somehow manages all these different brainwaves.
If you do much of any, there will probably be imposed rigidities and problems. I recommend brain wave training only if done in moderation and done wisely. Some brain waves between Alpha and Beta could probably help your Theta problem. Like a symphony, the higher and lower frequencies link and cohere with each other through harmonics.
What is the function of the various brainwaves?
When slower brainwaves are dominant we can feel tired, slow, sluggish, or dreamy. The descriptions that follow are only broad descriptions - in practice things are far more complex, and brainwaves reflect different aspects when they occur in different locations in the brain. Very little is known about infra-low brainwaves. Their slow nature make them difficult to detect and accurately measure, so few studies have been done. They appear to take a major role in brain timing and network function.
They are generated in deepest meditation and dreamless sleep.
Delta waves suspend external awareness and are the source of empathy. Healing and regeneration are stimulated in this state, and that is why deep restorative sleep is so essential to the healing process.
Theta waves 3 to 8 Hz Theta brainwaves occur most often in sleep but are also dominant in deep meditation. Theta is our gateway to learning, memory, and intuition.
