It was rhythmic with an 8-9-Hz alpha rhythm
, and no abnormalities were found.
This is the target for the detection of alpha waves by EEG, which normally occur in awake humans with closed eyes, and in a case of a distress the activity of the alpha rhythm
Due to time limitation between sessions, we often asked a preselected person with known high amplitude alpha rhythm
Jennifer then starts to ask questions about her and Marty's future self, but the Doc thought this to be a bad idea and activates a "Sleep-inducing Alpha Rhythm
Generator", a hand-held electronic gadget that emitted light which instantaneously put Jennifer to sleep.
How the alpha rhythm
manages to affect learning is something we investigate with computer models," said PD Dr.
Based on the above description, the most interesting and hopefully revealing are delta and theta rhythms, which have already been correlated with different brain disorders, and alpha rhythm
, because it represents the awake state that is most easily measured without distractions (subject is relaxed without mental activity).
EER registration was carried out during the period awakening between seizures in the condition of passive awakening and in 54% of cases dominant activity was presented by slow alpha rhythm
7-8-9 GC, 21%-teta-rhythm 5-6 GC, 18%-alpha rhythm
10-12GC, in 7% of cases-by alpha-beta rhythm 12-14 GC.
However, the abnormal alpha rhythm
could reflect a state of alertness during nocturnal sleep that would determine the subjective feeling of nonrestorative sleep.
In the first module, "cortical functioning," performed assessments on the basis of alpha-wave characteristics, including, nature of alpha rhythm
, alpha-rhythm frequency, amplitude, topography, amplitude asymmetry, and changes in alpha waves in response to the provocative tests (see Table 1).
Kennedy argued that the EEG alpha rhythm
is not a result of cellular activity but rather is an artifact due to the gross physical properties of materials from which the recordings are made (i.
l l l l l l PAUL CARBERRY , taken to hospital after suffering a fall on Alpha Rhythm
at Kilbeggan on Saturday evening, will not resume until Saturday.
The alpha rhythm
is mainly generated in the visual cortex occuring in the frequency range of 8-13 Hz.
