Interhemispheric binding of ambiguous visual motion is associated with changes in beta oscillatory activity but not with gamma range synchrony

Abstract/Results: ABSTRACT:
In vision, perceptual features are processed in several regions distributed across the brain. Yet, the brain achieves a coherent perception of visual scenes and objects through integration of these features, which are encoded in spatially segregated brain areas. How the brain seamlessly achieves this accurate integration is currently unknown and is referred to as the "binding problem." Among the proposed mechanisms meant to resolve the binding problem, the binding-by-synchrony hypothesis proposes that binding is carried out by the synchronization of distant neuronal assemblies. This study aimed at providing a critical test to the binding-by-synchrony hypothesis by evaluating long-range connectivity using EEG during a motion integration visual task that entails binding across hemispheres. Our results show that large-scale perceptual binding is not associated with long-range interhemispheric gamma synchrony. However, distinct perceptual interpretations were found to correlate with changes in beta power. Increased beta activity was observed during binding under ambiguous conditions and originates mainly from parietal regions. These findings reveal that the visual experience of binding can be identified by distinct signatures of oscillatory activity, regardless of long-range gamma synchrony, suggesting that such type of synchrony does not underlie perceptual binding.

Pivotal role of hMT+ in long-range disambiguation of interhemispheric bistable surface motion

Abstract/Results: ABSTRACT:
It remains an open question whether long-range disambiguation of ambiguous surface motion can be achieved in early visual cortex or instead in higher level regions, which concerns object/surface segmentation/integration mechanisms. We used a bistable moving stimulus that can be perceived as a pattern comprehending both visual hemi-fields moving coherently downward or as two widely segregated nonoverlapping component objects (in each visual hemi-field) moving separately inward. This paradigm requires long-range integration across the vertical meridian leading to interhemispheric binding. Our fMRI study (n=30) revealed a close relation between activity in hMT+ and perceptual switches involving interhemispheric segregation/integration of motion signals, crucially under nonlocal conditions where components do not overlap and belong to distinct hemispheres. Higher signal changes were found in hMT+ in response to spatially segregated component (incoherent) percepts than to pattern (coherent) percepts. This did not occur in early visual cortex, unlike apparent motion, which does not entail surface segmentation. We also identified a role for top–down mechanisms in state transitions. Deconvolution analysis of switch-related changes revealed prefrontal, insula, and cingulate areas, with the right superior parietal lobule (SPL) being particularly involved. We observed that directed influences could emerge either from left or right hMT+ during bistable motion integration/segregation. SPL also exhibited significant directed functional connectivity with hMT+, during perceptual state maintenance (Granger causality analysis). Our results suggest that long-range interhemispheric binding of ambiguous motion representations mainly reflect bottom–up processes from hMT+ during perceptual state maintenance. In contrast, state transitions maybe influenced by high-level regions such as the SPL

High-resolution 7T fMRI data on the perceptual long-range segregation vs. integration of bistable moving stimuli
Publication year: 2017

https://www.uc.pt/en/icnas/CIP2017/CIP2017_programme/CIP2017_abstractBook
Abstract/Results: ABSTRACT:
During continuous observation of a bistable moving stimulus, visual perception may alternate between competing interpretations, switching over time between alternative percepts. In bistability resulting from e.g. plaid stimuli, the question of how the visual system integrates global patterns of motion from its components becomes particularly salient. Here, we aimed to study the role of the human motion complex (hMT+), known to be involved in motion perception and to underlie the perceptual
binding of moving surfaces, in the integration of visual motion information across brain hemispheres.
We used a previously described bistable moving stimulus with non-overlapping 1D components presented to each hemisphere thereby requiring long-range integration. Accordingly, motion coherence requires interhemispheric binding and incoherence interhemispheric segregation. We took advantage of high-resolution 7 Tesla (7T) functional Magnetic Resonance Imaging (fMRI) to explore the relation between the hMT+ spatial and temporal activity patterns and bistable perception. fMRI data from 10 healthy participants were acquired and analyzed offline. The interhemispheric correlation of the bilateral hMT+ activity and its association with the perceptual states was estimated. Additionally, we investigated hMT+ functional sub-domains responding preferentially for each type of motion percept (coherent or incoherent) and tested whether these domains have different preference for axes of motion.
We found evidence for the existence of hMT+ perceptual sub-domains, which have shown preferred axes of motion matching the motion direction of the perceptual reports. Moreover, our results suggest that hMT+ has a functional role in integrating interhemispheric representations of bistable percepts. We found a close relation between the hMT+ interhemispheric functional connectivity and the perceptual switches involving differential long-range integration of visual moving stimuli.

The perceptual integration of visual motion revealed by hMT+ interhemispheric connectivity: a 7 Tesla study
Publication year: 2017

Abstract/Results: ABSTRACT:
The mechanism by which human vision segments and binds stimulus' features to produce a coherent percept is still not well-understood (Treisman, 1996; Burwick, 2014). Perceptual interpretation of ambiguous moving stimuli, for which perception alternates between competing interpretations in conditions of identical sensory input, raises the question of how the visual system integrates global patterns of motion from its components (Leopold and Logothetis, 1999; Sterzer et al., 2009). The human motion complex (hMT+) is well known to be involved in motion perception (Tootell et al., 1995; Kolster et al., 2010) and has been shown to underlie the perceptual binding of overlapping moving surfaces (Castelo-Branco et al., 2002). However, its role in interhemispheric integration of visual motion information was only explored with apparent motion paradigms (Sterzer et al., 2003; Muckli et al., 2005; Rose and Buechel, 2005; Genç et al., 2011). Here we aimed to investigate how perceptual visual motion integration vs. segregation of interhemispheric non-overlapping 1D directional cues is modulated by interhemispheric functional connectivity. A previously described ambiguous moving stimulus (Wallach, 1935; Wuerger et al., 1996), which can be perceived as a coherent pattern comprehending both visual hemi-fields or as two separate non-overlapping component surfaces (one in each visual hemi-field), was used. Data from nine healthy participants were acquired using high-resolution functional magnetic resonance imaging (fMRI) at 7T and analyzed offline to estimate the variation of hMT+ interhemispheric correlation in time. We found that hMT+ interhemispheric correlation changes in time depending on whether participants integrate all motion features into the percept of a single coherent pattern or whether they segregate visual motion features and perceive two separate surfaces. We present the first fMRI-based evidence of a close relation between interhemispheric functional connectivity in hMT+ regions and the perceptual switches involving differential long-range integration of visual moving stimuli.

Neural signatures of conscious visual perception: An EEG/ERP Study
Publication year: 2017

Abstract/Results: ABSTRACT:
Introduction: The neural mechanisms subserving visual information processing are fairly well understood, but the ones paving the way to perceptual visual awareness remain controversial. In order to shed light on this debate, we present an EEG/ERP study combining an oddball detection task at perceptual threshold of feature difference with a visual awareness paradigm based on contextual contrast detection. Keeping conditions invariant (target stimulus is sometimes detected and sometimes not), differences in measured activity should reflect specific neuroelectrical processes that correlate with distinct perceptual sates Methods: The study was conducted at IBILI/FMED of the University of Coimbra. 20 healthy volunteers, 9 males and 11 females (18-40YA, mean =30YO; SD=9), participated in the experiment. Differential thresholds for visual change detection were tested for each participant, in a psychophysical staircase task. Reference and comparison Test consisted of reddish-center/gray-surround circular patches, uniformly illuminated by experimentally rendered daylight illuminants. 47 Illuminants parametrically spaced along the daylight locus were tested. Subject adapted Targets at perceptual threshold of illuminant difference (from reference) were chosen for the Oddball EEG task. Data were segmented into epochs from -200ms to 1000ms, time-locked by stimuli category (Target/Standard), and awareness category (Detected/Non-detected), and averaged. Difference waves contrasting stimulus and awareness category were calculated for each participant. Results and conclusions. Processing differences between stimuli reaching awareness or unawareness and their evoked activity, started around 50ms after stimuli onset, with the Non-detected condition surprisingly eliciting significantly different occipital P1 sensory component, from both Standard and Detected condition, at shorter latencies. Electrophysiological differential onset for perceptual visual awareness-dependent processing started about 150ms, with significantly different posterior detection negatives and post perceptual parietal late positivities. This neural profile was not observed for the “unaware” condition. Results suggest that processing of visual features may occur in visual regions even when conditions of change do not reach awareness.

Abstract/Results: ABSTRACT:
BACKGROUND
Neural models of perceptual decision are often studied using bistable perceptual decision paradigms. Causal bottom vs top-down mechanisms remain to be elucidated.
AIMS
We asked whether hMT+ is pivotal for perceptual integration of motion signals in terms of bottom-up vs top-down interactions. Moreover, if middle temporal cortex (hMT+) is indeed a causal hub in the decision-making network, then it should also provide long range integration at the interhemispheric level, which is a testable prediction. We tested whether one can find fingerprints of perception related to neural coherence. Finally, we aimed to elucidate the general relation between sensory and decision modules within saliency and frontoparietal networks.
METHOD
We combined EEG and fMRI methods, to understand perceptual decision mechanisms, their neural correlates and functional connectivity (with a focus on interhemispheric interactions).
RESULTS
We found out that human hMT+ is a causal hub which contributes to maintain perceptual representations when other competing percepts are available for cognition. We further confirmed the prediction that it should also subserve long range perceptual integration, through increased interhemispheric connectivity between left/right hMT+. EEG data revealed that bound perceptual interpretations relate with parietal beta power under ambiguous conditions. Together with our findings using other decision paradigms inside and outside the visual domain, we showed a modular architecture of perceptual decision-making network.
CONCLUSION
Our work provides a clear-cut functional segregation at different time scales between sensory representations, and the role of the general decision modules within saliency and frontoparietal networks.

Mechanisms of speed encoding in the human middle temporal cortex measured by 7T fMRI
Publication year: 2023

https://onlinelibrary.wiley.com/doi/10.1002/hbm.26193
Abstract/Results: ABSTRACT:
Perception of dynamic scenes in our environment results from the evaluation of visual features such as the fundamental spatial and temporal frequency components of a moving object. The ratio between these two components represents the object's speed of motion. The human middle temporal cortex hMT+ has a crucial biological role in the direct encoding of object speed. However, the link between hMT+ speed encoding and the spatiotemporal frequency components of a moving object is still under explored. Here, we recorded high resolution 7T blood oxygen level-dependent BOLD responses to different visual motion stimuli as a function of their fundamental spatial and temporal frequency components. We fitted each hMT+ BOLD response with a 2D Gaussian model allowing for two different speed encoding mechanisms: (1) distinct and independent selectivity for the spatial and temporal frequencies of the visual motion stimuli; (2) pure tuning for the speed of motion. We show that both mechanisms occur but in different neuronal groups within hMT+, with the largest subregion of the complex showing separable tuning for the spatial and temporal frequency of the visual stimuli. Both mechanisms were highly reproducible within participants, reconciling single cell recordings from MT in animals that have showed both encoding mechanisms. Our findings confirm that a more complex process is involved in the perception of speed than initially thought and suggest that hMT+ plays a primary role in the evaluation of the spatial features of the moving visual input.
