摘要：

The mechanism for generation of the alpha rhythm is controversial. In the current study, analysis in the time and frequency domains revealed that the alpha rhythm recorded from the scalp overlying the human occipital cortex can be entrained to the second or third harmonic of low frequency light flashes. These results support the view that the alpha rhythm is generated by a nonlinear oscillator rather than a narrow-band transmission system acting as a filter. (C) 1999 Elsevier Science B.V.
