Temporal coherence and attention in auditory scene analysis

Abstract: Humans and other animals can attend to one of multiple sounds, and follow it selectively over time. The neural underpinnings of this perceptual feat remain mysterious. Some studies have concluded that sounds are heard as separate streams when they activate well-separated populations of central auditory neurons, and that this process is largely pre-attentive. Here, we argue instead that stream formation depends primarily on temporal coherence between responses that encode various features of a sound source. Fur… Show more

“…Furthermore, changes in temporal and spectral signal features are other factors for an enhanced annoyance response found in laboratory and field studies [61][62][63]. These results are in compliance with neuro-biological and hearing research on the spectrotemporal filter mechanism of auditory attention [64][65][66][67]. If permanent changes of the temporal and frequency features occur the auditory system has difficulties to habituate and adapt-especially during nighttime.…”

“…To rise to the challenge of understanding speech perception, several theories have been proposed on the role of neural oscillations in speech perception (e.g. Ghitza, 2011;Ghitza & Greenberg, 2009;Giraud & Poeppel, 2012;Howard & Poeppel, 2010;Peelle, 2012;Poeppel, 2003;Shamma, Elhilali, & Micheyl, 2011). For instance, Giraud and Poeppel (2012) proposed that the spike train input to auditory cortex (which captures the energy fluctuations of the speech signal) influences neuronal excitability: the neurons in primary auditory cortex would adjust (reset) the phase of their excitability rhythm thereby allowing them to entrain to the rhythmic regularities of the speech signal.…”

“…We argue that high spectral resolution can support sound segregation and, as a result, selective attention can operate on the individually perceived auditory objects, enhancing the neural representation of the attended speech and suppressing the neural representation of unattended speech (Horton et al 2013;Kong et al 2014). The brain can do so by using temporal coherence to bind together acoustic features belonging to the same speech stream (Shamma et al 2011) or by predicting which moments contain more information about the attended speech than the competing speech (Schroeder et al 2008;Schroeder and Lakatos 2009;Zion-Golumbic et al 2013).…”
