Scientists measuring brain activity have found that in many regions, such as the sensory or motor cortex, activity sometimes
oscillates at different frequencies, forming wave - like patterns.
At any one time, brainwaves
oscillating at different frequencies and associated with different tasks sweep through the brain.
The constant activity of the brain is observed as brainwaves that
oscillate at different frequencies in different brain areas which keep a steady «beat».
Not exact matches
The results are striking: since the electromagnetic field steadily
oscillates at a very high
frequency, any noise or disturbance
at a
different frequency results in a zero net effect.
