Alpha waves again gained interest in regards to an engineering approach to the science fiction challenge of psychokinesis, i.e. control of movement of a physical object using energy emanating from a human brain. In 1988, EEG alpha rhythm was used in a brain–computer interface experiment of control of a movement of a physical object, a robot.
Rob Dehlinger is a singer, trumpet player, and composer living in the San Francisco Bay Area.He is the frontman for “Robert Dehlinger’s Alpha Rhythm Kings”. As a live trumpeter and backup vocalist Rob has worked with many performers including Ledisi, Wanda Jackson, Dan Aykroyd, Meat Loaf, Michael Bolton, and Lena Prima.
This was the "posterior basic rhythm" (also called the "posterior dominant rhythm" or the "posterior alpha rhythm"), seen in the posterior regions of the head on both sides, higher in amplitude on the dominant side. It emerges with closing of the eyes and with relaxation, and attenuates with eye opening or mental exertion.
[114] [115] Alpha rhythm based BCI was the first BCI for control of a robot. [ 116 ] [ 117 ] 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.
Hans Berger (21 May 1873 – 1 June 1941) was a German psychiatrist. He is best known as the inventor of electroencephalography (EEG) in 1924, which is a method used for recording the electrical activity of the brain, commonly described in terms of brainwaves, and as the discoverer of the alpha wave rhythm which is a type of brainwave.
One second sample of an EEG alpha oscillations. This rhythm occurs at frequencies similar to the mu rhythm, although alpha oscillations are detected over a different part of the brain. The left motor cortex, or BA4, is highlighted in green on this left lateral view of the brain. This is the area over which mu rhythms are detected bilaterally.
[23] Furthermore, they suggest that the alpha rhythm could be the "natural resonance frequency of the visual cortex during the waking state, whereas the alpha activity that appears in the drowsiness period at sleep onset could be indexing the hypnagogic imagery self-generated by the sleeping brain, and a phasic event in the case of REM sleep."
Thalamocortical alpha frequency oscillations have been noted in the human occipital-parietal cortex. This activity could be originated by the pyramidal neurons in layer IV. [ 3 ] It has been shown that alpha rhythms seem to be related to the focus of one's attention: external focus on visual tasks diminishes alpha activity while internal focus ...
