Dissecting neural circuits for multisensory integration and crossmodal processing

Jeffrey M. Yau, Gregory C. DeAngelis, Dora E. Angelaki
2015 Philosophical Transactions of the Royal Society of London. Biological Sciences  
Our multisensory experience of the world depends on the brain's remarkable ability to combine signals across sensory systems.  ...  One contribution of 15 to a theme issue 'Controlling brain activity to alter perception, behaviour and society'.  ...  Visual and vestibular cues combine near-optimally to inform our perception of heading, which is the direction of translational self-motion [116] .  ...

2013 Recent Advances in Autism Spectrum Disorders - Volume II  
rather than in their own, they offer a mechanism by which a minicolumn can inhibit its immediate neighbors.  ...  This determination of modularity is derived from a self-organizing process that takes place via dynamic interactions between minicolumns and columns in the cortex both during and after development.  ...

Keeping in Touch with Mental Health: The Orienting Reflex and Behavioral Outcomes from Calatonia

Anita Ribeiro Blanchard, William Edgar Comfort
2020 Brain Sciences  
This article describes a well-defined protocol of touch therapy in the context of psychotherapy—the Calatonia technique—which engages the orienting reflex.  ...  Physical and psychological therapy based on touch has been gradually integrated into broader mental health settings in the past two decades, evolving from a variety of psychodynamic, neurobiological and  ...  Excluding the tenth point (the head), the first nine points of tactile contact are bilateral (the same tactile stimulus is simultaneously held on each side of the body).  ...

Selective Attention Gates the Interactive Crossmodal Coupling between Perceptual Systems

Silvia Convento, Md. Shoaibur Rahman, Jeffrey M. Yau

Convento et al. show that transcranial magnetic stimulation (TMS) targeting somatosensory cortex selectively impairs auditory perception depending on modality-and feature-based attention.  ...  dependence on task demands [51] .  ...  On each trial, subjects experienced 1 auditory stimulus and 1 tactile stimulus sequentially (duration: 300msec, inter-stimulus interval: 500msec, stimulus frequency: 200Hz) and reported which stimulus  ...

Vectorial versus configural encoding of body space [chapter]

Jacques Paillard
2005 Advances in Consciousness Research  
In interdisciplinary workshop like this, each of us, depending on his own background and experiences, is necessarily coming with his biased point of view.  ...  The way in which space relationships are represented in the brain and intervene to organize our vision of a stable world in which we move our private body space has been the topic of lasting philosophical  ...  Indeed organism may be defined as "living entity with interrelated parts, dependant of each other and which work together to preserve and maintain their coexistence".  ...

Individual Alpha Frequency Predicts Perceived Visuotactile Simultaneity

Daniele Migliorati, Filippo Zappasodi, Mauro Gianni Perrucci, Brunella Donno, Georg Northoff, Vincenzo Romei, Marcello Costantini
2019 Journal of Cognitive Neuroscience  
We propose that the length of an alpha cycle constrains the temporal resolution within which perceptual processes take place.  ...  Furthermore, we found that higher prestimulus alpha power measured over the same left parietal regions accounted for more veridical responses of nonsimultaneity, which may be explained either by accuracy  ...  Negative SOAs indicate a trial in which the visual stimulus was presented first, whereas positive SOAs indicate a trial in which the tactile stimulus was presented first.  ...

Embodied simulation: From neurons to phenomenal experience

Vittorio Gallese
2005 Phenomenology and the Cognitive Sciences  
A common functional mechanism is at the basis of both body awareness and basic forms of social understanding: embodied simulation.  ...  Neuroscientific research also shows that there are neural mechanisms mediating between the multi-level personal experience we entertain of our lived body, and the implicit certainties we simultaneously  ...  Acknowledgments A preliminary version of this paper has been presented at the Annual Meeting of the American Philosophical Association, Central Division, held in Chicago on April 23-25 2004.  ...

Reduced C-afferent fibre density affects perceived pleasantness and empathy for touch

India Morrison, Line S. Löken, Jan Minde, Johan Wessberg, Irene Perini, Inger Nennesmo, Håkan Olausson
2011 Brain  
Hence, perception of the hedonic aspect of dynamic touch likely depends on C-tactile afferent density.  ...  Further, patients' blood-oxygen-level-dependent responses in posterior insular cortex-a target for C afferents-were not modulated by stimulation optimal for activating C-tactile afferents.  ...  Self-related and other related evaluations may follow different, relatively independent norms, depending on experience and context.  ...

Congenital deafness is associated with specific somatosensory deficits in adolescents

Rabih Moshourab, Valérie Bégay, Christiane Wetzel, Jan Walcher, Steven Middleton, Manfred Gross, Gary R. Lewin
2017 Scientific Reports  
Hearing and touch represent two distinct sensory systems that both rely on the transformation of mechanical force into electrical signals.  ...  These sensory changes were not accompanied by any major change in measures of pain perception.  ...  We thank the schools (Margaretha-von-Witzleben, Rosa-Luxemburg, and Robert-Havemann School) for their participation and organization and assistance in providing space and time-plan to carry out these studies  ...

Here we report a functional magnetic resonance imaging study in which the effects on sensation of varying the occurrence, timing and force of movements were measured.  ...  We observed that tactile-related activity in a region of secondary somatosensory cortex is reduced when sensation is associated with movement and further that this reduction is maximal when movement and  ...  The factors were 1) the presence or absence of self-generated movement, that is the right finger tap on the upper sensor (M -0/1); 2) the presence or absence of a tactile stimulus was delivered to the  ...
