“…Of the earlier components, the N1 seems to be the most closely related to conscious state [74,239,240,242,246,247,253]. While some have identified the middle-latency and associated auditory steady-state responses as potential markers [251], we know from other studies that these responses are themselves insufficient to infer consciousness [108]. However, the absence of these responses is taken to be a strong indicator of unconsciousness [252].…”

Cariani 2 and Alexander Gutschalk 1 1 Department of Neurology, Ruprecht-Karls-Universität Heidelberg, Heidelberg, Germany 2 Hearing Research Center, Boston University, Boston, MA, USA ARD, 0000-0001-8075-6374How and which aspects of neural activity give rise to subjective perceptual experience-i.e. conscious perception-is a fundamental question of neuroscience. To date, the vast majority of work concerning this question has come from vision, raising the issue of generalizability of prominent resulting theories. However, recent work has begun to shed light on the neural processes subserving conscious perception in other modalities, particularly audition. Here, we outline a roadmap for the future study of conscious auditory perception and its neural basis, paying particular attention to how conscious perception emerges (and of which elements or groups of elements) in complex auditory scenes. We begin by discussing the functional role of the auditory system, particularly as it pertains to conscious perception. Next, we ask: what are the phenomena that need to be explained by a theory of conscious auditory perception? After surveying the available literature for candidate neural correlates, we end by considering the implications that such results have for a general theory of conscious perception as well as prominent outstanding questions and what approaches/techniques can best be used to address them.This article is part of the themed issue 'Auditory and visual scene analysis'. IntroductionHow subjective perceptual experience-i.e. conscious perception-emerges from patterns of brain activity is a fundamental question of modern neuroscience. Although relationships between neural activity and conscious perception have been pondered since the beginning of the mind-brain sciences [1][2][3][4][5][6], many have viewed the problem as scientifically intractable. However, employing increasingly powerful methods [7], recent years have seen a dramatic increase in studies pursuing the so-called neural correlates of consciousness, or NCC [8], defined as the 'the minimal set of neural events jointly sufficient for a specific conscious experience' [9] (e.g. the phenomenal experience of hearing a sound). This definition, in contrast with others that distinguish between the NCC and the NCCC (neural correlates of the contents of consciousness), subsumes both the 'preconditions' and content-specific processes associated with specific conscious percepts [10], acknowledging that all conscious experiences have content (though varying in richness [11,12], an idea also underscored by early auditory selective-a...

“…No specific suggestion was proposed for the processes critical for perception. However, it was hypothesized that consciousness was identical with the spatiotemporal pattern of an electromagnetic field surrounding neuronal activity rather than the firing of particular neurons (Pockett, 1999).…”

“…There are many possible reasons for this variability, but the upshot of it is that I am quite happy to state here and now that my choice of a figure of 80 ms for the latency of simple sensation might well be wrong-or it might be right for some subjects and not others, or it might be right for some sensory systems and not others (e.g., for somatosensation but not for vision), or it might be right for some feature of conscious perception and not others (e.g., within the visual system for color or motion but not for metacontrast), or it might be right for any particular subject/sensation combination when the subject is paying attention to the stimulus and not when they're not-and so on. My personal working hypothesis at this stage is that conscious sensations/perceptions evolve over time, starting from about 60-80 ms poststimulus for a simple sensation (Pockett, 1999) and continuing up to at least 300 ms and possibly longer if one includes perceptions to do with comparison of the just-felt simple sensation to previous sensations and decisions on what to do or say about the whole business. In fact, it seems likely that much of the difficulty with interpretation of Libet's data follows from the fact that, like everyone else in the business so far, he failed to find a way of distinguishing clearly between simple sensation per se and the various comparisons, interpretations, and decisions which follow hard thereon, being necessary intermediaries for reportage of the sensation.…”
