Neurofeedback alerts the patient when beta waves are present.

Some years ago researchers found that we can control our mental alpha and beta waves by directing our thoughts.

For some time now, I have had what looks like a hippie headband that picks up my alpha and beta waves.

The other flickers at the frequency of brain waves associated with concentration, known as beta waves.

Then some beta waves appeared.

The muscles still tensed, the beta waves still whipping me along when all I wanted to do was rest, and wait for nightfall.

At three in the morning, another burst of theta and beta waves had crossed the EEG screen.

Beta waves correspond to normal conscious brain activity, ranging from calm and relaxed consciousness, to fight-or-flight panic.

Far away, Dussander recited pulse, blood pressure, respiration, alpha waves, beta waves, stroke count.

There is also something called sensory motor rhythm, or S.M.R., which is a similar frequency to beta waves.

In addition to alpha waves, there are also beta waves, representing a faster cycle, from 14 to 50 per second, and a smaller fluctuation in potential.

As he related his findings to Rachel, David's theta and beta waves vanished from the EEG screen.

Or hook up an encephalograph with a cathode ray tube that her mother could see, and teach her to modulate her beta waves.

Low amplitude beta waves with multiple and varying frequencies are often associated with active, busy, or anxious thinking and active concentration.

Mori performed an experiment at Tokyo's Nihon University designed to measure the effect of video games on human brain activity by examining beta waves.

Most of the research has focused on easily observed phenomena like alpha and beta waves, which have been respectively linked to activities including sleep and heightened alertness.

Over the motor cortex beta waves are associated with the muscle contractions that happen in isotonic movements and are suppressed prior to and during movement changes.

Mori's theory was criticized as unwarranted research by established neuroscientists and brain specialists, because he used unreliable measures and misinterpreted the fluctuation of beta waves.

So you could learn to turn Beta waves into Alpha waves and Alpha waves into Theta waves, etc.

In 1899, Rutherford discovered alpha and beta waves, Freud wrote "The Interpretation of Dreams" and the Philippines demanded independence from the United States.

A SESSION at Synchro-Energize attempts to increase calming, creative theta waves and reduce hyperactive beta waves.

It settled its tendrils firmly along the neuron channels of the man's brain and tapped the brain's obsession, using the feedback to power a counterobsession, stroking McCloud's beta waves.

Pre-sleep is the period of decreased perceptual awareness where brain activity is characterized by alpha waves which are more rhythmic, higher in amplitude and lower in frequency compared to beta waves.

Benzodiazepines In low doses, the anxiolytic action of benzodiazepines tends to decrease the percentage of alpha activity while increasing the prevalence of beta waves over 18 Hz [ 8].

We've got alpha waves, beta waves, delta waves, theta waves; different variations at different times, depending on whether eyes are open or closed, whether the subject is awake, meditating or asleep.

"Beta rhythm," she said, pointing to the scope in the center of the board.

The beta rhythm occurs in the prefrontal regions and has been associated with increased cognitive activity.

This is called the beta rhythm.

It was concluded that PTNs in the motor cortex directly influence the generation of Beta rhythms.

After investigation of the components in EEG, motor imagery related mu and beta rhythms were selected for the information sources of the system.

He first identified the alpha rhythm, which he called the Berger rhythm, and later identified the beta rhythm and sleep spindles.

He demonstrated that alterations in consciousness are associated with changes in the EEG and associated the beta rhythm with alertness.

In particular, some forms of BCI allow users to control a device by measuring the amplitude of oscillatory activity in specific frequency bands, including mu and beta rhythms.

Birbaumer's later research with Jonathan Wolpaw at New York State University has focused on developing technology that would allow users to choose the brain signals they found easiest to operate a BCI, including mu and beta rhythms.

In order to discriminate left and right hand movement imagery, three different feature extraction methods was developed using: Discrete Wavelet transform, Power Spectrum transform and Band Pass FIR filters for Mu and Beta rhythms.
