Neural oscillations (brainwaves) are synchronized rhythmic or repetitive firing patterns of neurons in the brain. These patterns occur when neurons fire together, then become suppressed, then fire together again, and so forth. Oscillations are thought to be a natural timing mechanism in the brain for dynamic processing of cognitive functions occurring at multiple levels (e.g. dynamic processing of attention, perception, memory, motor control, etc.). Neurons can, and often do, oscillate at the rate of 1,000 to 2,000 times per second.
