I am going to the 2007 American Epilepsy Society annual meeting in Philadelphia, PA next weekend and intend to present a poster half of which will deal with multi-taper spectral analysis. I am presenting it next Monday morning, from 8:00AM to 2:00PM (poster #3.165). I could also use some suggestions for a good place to get a cheese steak.
The novelty of this presentation is that I am using orthogonal Slepian tapers to determine both the amplitude and phase of a complex transfer function, where most of the previous research deals with amplitude spectra alone. The difficulty is that the various tapers have different phase-bias characteristics, so averaging them and then computing the phase and amplitude would not work. Nevertheless, if we first compute the power in different bands, per taper, and then average, the phase dispersion will not play an important role. The second part of the presentation will deal with causing the activity of an on-going, epileptic seizure to become temporarily phase-locked to applied electrical stimulation (entrainment). The technical abstract for the poster presentation is below.
