1. compare and contrast synchrony and alpha block.
2. does the beta rhythm become more pronounced in the " eyes open" state?
3. The amplitude measurements( stddev) are indicative of how much alpha activity is occurring in the subject. But the amplitude values for beta do not truly reflect the amount of mental activity occuring with the eyes open. Explain why?
4. Explain the delta and theta rhythm. is there an increase in delta and theta activity when the eyes are open?

Thank you very , very much.

Yes, the beta rhythm is characteristic of more alert states so there will be a shift in frequency away from the alpha rhythm (so the alpha rhythm will decrease). However, the amplitude of the beta rhythm may not increase when the eyes are open. The change in mental activity causes both positive and negative inputs to be generated at the same time. The negative inputs subtract from the positive inputs producing lower waveform amplitudes.
