Temporal resolution of CWT

Dear all,

I have a general question concerning wavelet decomposition of an EEG-Signal sampled with a frequency of 250. We analysed the data with a Morlet wavelet (central frequency = 7) and when we regard the time-frequency/(scale) plot, results appear plausible. However I'm not sure what my temporal resolution is exactly. I have tried to find something in some recent works with a similar approach but was not able to find anything. Does anybody know some literature which could help me or can just tell me how to find out the resolution at the different scales?

Thanks in advance

David
