“…High-resolution scanning would allow identifying correlated activity of a smaller number of neurons across subjects, but it may reduce ISC as it also increases the effects of anatomical variability. It is thus important to investigate in designs that have greater statistical power but which are still applicable to exploratory approaches such as wavelet correlation (Lessa et al, 2011 ).…”

“…with no predefined fixation points) of complex scenes of moving stimuli with a longer duration that is closer to real life than precisely parameterised stimuli. Intersubject correlation (ISC) is one method alongside other recent developments in neuroscience such as independent component analysis (Bartels & Zeki, 2004 ; Wolf, Dziobek, & Heekeren, 2010 ), Wavelet correlation (Lessa et al, 2011 ), or event boundary analysis (Zacks et al, 2001 ; Zacks, Speer, Swallow, & Maley, 2010 ), which enable analyses of fMRI data recorded while presenting stimuli that fulfil these criteria (Hasson, Nir, Levy, Fuhrmann, & Malach, 2004 ).…”

“…Therefore, these areas can be identified by testing for correlated BOLD time-courses between subjects (“synchronization”). This approach has now been employed with a variety of stimuli and tasks (e.g., palm trees task, Seghier and Price, 2009; face processing, Lessa et al, 2011; story comprehension, Lerner et al, 2011; movie watching, Kauppi et al, 2010; representation of action-schemas, Hanson et al, 2009).…”

“…A few papers recently published have reported on the effectiveness of WT applied to the EEG signal for representing various aspects of non-stationary signals such as trends, discontinuities, and repeated patterns where other signal processing approaches fail or are not as effective (Adeli et al, 2003;Asaduzzaman et al, 2010;Guo et al, 2009;Lessa, 2011), but there are still some problems with classical EEG analysis and classification (Arab et al, 2010;Bauer et al, 2008;Oehler et al, 2009). It is important to emphasize the algorithm for classification of EEG signals based on WT and Patterns Recognize Techniques.…”
