“…Historically, the combined percept has not been considered, and to now, only behavioral evidence supports that it is separate from the two main (segregated and integrated) alternatives (Denham et al, 2013(Denham et al, , 2012(Denham et al, , 2014Farkas et al, 2016aFarkas et al, , 2016bKondo et al, 2017). The current data shows that the perception of the combined pattern is associated with stronger connections in a different frequency band than perception of the segregated pattern.…”

“…Transition matrices, containing conditional probabilities for transitions between perceptual alternatives, were constructed from the perceptual reports using the method described in Denham et al (2012). Transition matrices had 4 rows and 4 columns (each corresponding to one of the 4 alternative perceptual choices described above) with cells representing the conditional probability of the percept changing from the starting percept (column) to the percept assigned to the row; the diagonal contained the probability of no change.…”

“…The conditional probabilities were estimated for each listener and stimulus block, separately (block transition matrix), for each listener (by pooling data from all stimulus blocks of a listener: listener transition matrix), and for the whole experiment (by pooling data from all blocks and participants: global transition matrix). Denham et al (2012) showed that the global transition matrix can be used to optimally estimate missing data (i.e., unobserved transitions) for individual listeners while listener transition matrices can be used for estimating missing data in the individual's block transition matrices. This procedure was employed for substituting missing data.…”

“…1 Please note that these studies only took into account the integrated and segregated perceptual alternatives. Denham et al (2014) studied individual differences in the perception of the auditory streaming stimulus, characterizing participants' switching patterns by the conditional probabilities for transitions between perceptual alternatives (Denham et al, 2012). These authors found that although perceptual switching is stochastic, the characteristics of participants' switching patterns tended to be idiosyncratic (switching patterns from the same individual across repeated blocks were significantly more similar in comparison with those of other participants) and stable (individual similarity was preserved across sessions separated by more than a year).…”

Functional brain networks underlying idiosyncratic switching patterns in multi-stable auditory perception

In perceptual multi-stability, perception stochastically switches between alternative interpretations of the stimulus allowing examination of perceptual experience independent of stimulus parameters. Previous studies found that listeners show temporally stable idiosyncratic switching patterns when listening to a multi-stable auditory stimulus, such as in the auditory streaming paradigm. This inter-individual variability can be described along two dimensions, Exploration and Segregation. In the current study, we explored the functional brain networks associated with these dimensions and their constituents using electroencephalography. Results showed that Segregation and its constituents are related to brain networks operating in the theta EEG band, whereas Exploration and its constituents are related to networks in the lower and upper alpha and beta bands. Thus, the dimensions on which individuals' perception differ from each other in the auditory streaming paradigm probably reflect separate perceptual processes in the human brain. Further, the results suggest that networks mainly located in left auditory areas underlie the perception of integration, whereas perceiving the alternative patterns is accompanied by stronger interhemispheric connections.

“…Support for the assumption that this is possible comes from studies showing that the dynamics of auditory and visual perceptual switches are similar. In both modalities percept durations are gamma distributed and have similar lengths (Pressnitzer and Hupé, 2006; Denham et al, 2012). Furthermore, the different modalities seem to share common brain regions for perceptual organization (Cusack, 2005).…”

Online tracking of the contents of conscious perception using real-time fMRI

et al. 2014

Perception is an active process that interprets and structures the stimulus input based on assumptions about its possible causes. We use real-time functional magnetic resonance imaging (rtfMRI) to investigate a particularly powerful demonstration of dynamic object integration in which the same physical stimulus intermittently elicits categorically different conscious object percepts. In this study, we simulated an outline object that is moving behind a narrow slit. With such displays, the physically identical stimulus can elicit categorically different percepts that either correspond closely to the physical stimulus (vertically moving line segments) or represent a hypothesis about the underlying cause of the physical stimulus (a horizontally moving object that is partly occluded). In the latter case, the brain must construct an object from the input sequence. Combining rtfMRI with machine learning techniques we show that it is possible to determine online the momentary state of a subject's conscious percept from time resolved BOLD-activity. In addition, we found that feedback about the currently decoded percept increased the decoding rates compared to prior fMRI recordings of the same stimulus without feedback presentation. The analysis of the trained classifier revealed a brain network that discriminates contents of conscious perception with antagonistic interactions between early sensory areas that represent physical stimulus properties and higher-tier brain areas. During integrated object percepts, brain activity decreases in early sensory areas and increases in higher-tier areas. We conclude that it is possible to use BOLD responses to reliably track the contents of conscious visual perception with a relatively high temporal resolution. We suggest that our approach can also be used to investigate the neural basis of auditory object formation and discuss the results in the context of predictive coding theory.
