Question by Merry_Jo: Where can I buy a machine or tools that can read our brainwave?
I like to have one that can show the graphic and the reading in number.
How much does it cost?
Can you direct me to the link, please? Thank you.

Sam’s Club. Probably over a hunert dollars.

Question by Tispy: How do sine waves and triangle waves affect the brain?
I’ve been listening to brain wave music and I’m wondering if these wave labels are grouped into something else I might know like Gamma, Theta, delta, alpha, beta?
Anyways, I’m curious, thanks.

ALPHA waves are of that type, see the link below.

Question by : Science. need your help!?
1) Describe the difference between wavelength and wave amplitude.
2) White light contains many colors. How is it that a shirt can appear to be blue when it is being lit with a white light?
3) List five regions of the invisible electromagnetic spectrum. For each region, state whether the electromagnetic waves are longer or shorter than that of visible light.
4) Describe how radio waves can be used to form an image of a human brain.
5) what properties do light waves and the the waves in a fishpond share?
6)Suppose a series of waves passes under a dock. A) what is the frequency of waves if 14 crests pas the dock in 7 s? B) ” ” 30 crests pass the dock in 5 s? C) ” ” one half passes the dock in 10 s?
7) Explain why it is not possible to increase a wave’s wavelength and frequency at the same time.
what are the contrasts and compares of infrared waves, visible light and x-rays?

Answer by Jim
1)
In electromagnetic radiation the amplitude is merely the beam intensity at its electric or its magnetic peak.
2)
If white light his a blue shirt you see blue because of the energy levels of the blue pigment in the shirt dye.
3)
Radio waves – much longer
infrared – longer
X-rays – much shorter
gamma ray – much shorter
ultraviolet – shorter
4)

5)
Indentifiable wavelength and frequency. Also, these waves constitute the motion of energy.
6)
14/7 = 2 Hz
30/5 = 6 Hz
0.5/10 = 0.05 Hz
7)
The wavelength and frequency are always inversely related by definition.
IR transfers heat. The waves are a tad longer than visible light.
Visible light is attenuated by the optic nerve so that we “see” them.
X-rays have extremely short wavelengths. They possess high energy. They can be used to image hidden objects and also detect atomic-level features in crystals.

Question by Ovulation Dinner Party: Neural activity within the brain can be observed and graphed using EEG. But are the frequencys\waves as on…?
paper the way brain activity functions?
I mean does our brain work in wave motion as is on paper from a EEG machine.
Sorry English is not my mother tongue.

Answer by LAlawMedMBA
No, brain activity is not very well represented by waves, especially in two dimensions. Brain activity is too complex to illustrate in full for graphical purposes, but it is both biochemical (in the form of neurotransmitters that send signals across synapses between neurons) and electrophysiological (in the form of saltatory conduction, primarily through sodium channels along neurons.

Q&A: Any comments on brainwave entrainment and resonance with terrestrial stationary waves?
by mrbichel
Question by Invisible_Flags: Any comments on brainwave entrainment and resonance with terrestrial stationary waves?
Like when a pair of similarly tuned piano forks are brought close together, when only one has been struck and set to oscillate, the other sympathetically vibrates. It has been proposed that the cortical rhythms can resonate with the earth’s electromagnetic stationary waves through a similar frequency-following response.
I’ve been reading a combination of Tesla’s works as well as some discussions on brainwave activity during meditative states and noticed a strong parallel similarity with the brain and the planet’s electromagnetic rhythms.
I am curious what others have to say, and any direction given to pursue this further. Thanks.

Rhythm detection is controlled by some areas of the brain such as the Cerebellum and a tiny structure called Suprachiasmatic Nucleus (SCN) which controls our body clock for many cyclical processes. While they influence parts of the brain in response to rhythms (through learning and practice of course), they dont influence the whole brain.
This means, soundwaves and rhythms are processed differently in the brain from electromagnetic waves, so treat them separately.
Not sure about brainwave activity during meditative stage but you must remember that brainwave activity as measured by EEG or electroencephalogram only measures brainwave activity that is summed up and averaged. It also only measures activity of the brain nearest to the scalp; not the deeper areas like the ones i mentioned that controlled rhythms. The measure of brainwave activity is an average, not a total measurement of activity.
But, some people have found therapeutic benefits (backed up with some research too) in Magnetic Resonance Imaging scans. The machine takes images by using huge powerful magnets to change the direction of electrons in our brain cells for a split second. Little is known of this effect, but so far it has not been proven to be damaging.
Also Electroconvulsive therapy and Deep Brain Stimulation, both of which involve using mild electric currents to run through parts of the brain, has shown some therapeutic benefits for some disorders, although very little is known on how it does so. Yet it is still used as a treatment!
You might want to look up more on Deep Brain Stimulation, and your theories about electricity and Tesla’s works to come up with your own explanation of electrical regulation in the brain =)
