...This selectivity itself seems to sharpen as a sentence unfolds....

...…in regions closer to auditory cortex are consistent with findings that sensory areasmaintain representations for both attended and ignored speech (Ding and Simon, 2012b), as well as with classic findings for modulation of simple sensory responses by attention (Hillyard et al., 1973; Woldorff et…...

...We speculate that this reflects contamination from onset responses which occur during the beginning of the sentence (Ding and Simon, 2012b) as a larger response during the first epoch is found across both electrode groups and frequency bands....
[...]
...Using converging analytic approaches we confirm that both low-frequency phase (Ding and Simon, 2012b; Kerlin et al., 2010) and high gamma power (Mesgarani and Chang, 2012) concurrently track the envelope of attended speech....

...This is in line with previous findings that both LF and HGp speech tracking responses are modulated by attention and are not simply a reflection of global acoustical input (Ding and Simon, 2012a, 2012b; Kerlin et al., 2010;Mesgarani and Chang, 2012)....

...These data suggest, as has been done before (Ding and Simon 2012a), that attended speech is not simply more strongly represented by the same neural generators, but rather that both speech streams are represented separately in the neural data....
[...]
...Previous research (Ding and Simon 2012a) has shown that attended and unattended speech can be extracted separately from neural data, implying that it is not just the case that attended speech is more strongly represented by the same neural generators....

...Using magnetoencephalography (MEG), which is a more global measure of cortical activity, Ding and Simon (2012a) showed that responses to a single-trial speech mixture could be decoded to give an estimate of the envelope of the input speech stream, and that this estimate typically had a greater…...

...Recent research in this area has focused on changes in cortical activity that track the dynamic changes in the speech stimulus (Kerlin et al. 2010; Ding and Simon 2012a; Koskinen et al. 2012; Mesgarani and Chang 2012; Power et al. 2012; Zion Golumbic et al. 2013)....

...This stimulus-reconstruction approach has been shown to be exquisitely sensitive to selective attention in a multispeaker environment (Ding and Simon 2012a, 2012b; Zion Golumbic et al. 2013)....

...The slow temporal modulations and coarse spectral modulations reflect the rhythm of speech and contain syllabic and phrasal level segmentation information (Greenberg 1999) and are particularly important for speech intelligibility (Shannon et al. 1995)....

...In quiet, these slow modulations, in concert with even a very coarse spectral modulation, accomplish high speech intelligibility (Shannon et al. 1995)....

...Experiments using dichotically presented tone sequences have demonstrated that the effect of attention on the M100 (N1) is observed for stimuli with some kinds of rhythm (typically fast) (Ahveninen et al. 2011; Hillyard et al. 1973; Power et al. 2011; Rif et al. 1991; Woldorff et al. 1993), but not others (Hari et al....
