<DIV>Hi, everyone</DIV>
<DIV> </DIV>
<DIV> I want to how does the STUDY module compute the ERSP using the default parameters. </DIV>
<DIV> Suppose at 3 Hz, the baseline power is a, and the power at 3 Hz, 200 ms is b. Then how does the ERSP value at 3 Hz, 200 ms is calculated?</DIV>
<DIV> Is one of the following formula correct ? (1) ERSP = 10*log10(b/a); (2) ERSP = (b-a)/a</DIV>
<DIV> </DIV>
<DIV> Thank you !</DIV>
