Changing Finger Movement Perception: Influence of Active Haptics on Visual Dominance

Ronan Boulic, Bruno Herbelin, Loën Boban

The perception of one’s own body is a complex mechanism that can be disturbed by conflicting sensory information and lead to illusory (mis-) perceptions. Prominent models of multisensory integration propose that sensory streams are integrated according to ...

Blind as a bat: spatial perception without sight

Frederike Dümbgen

Among our five senses, we rely mostly on audition and vision to perceive an environment. Our ears are able to detect stimuli from all directions, especially from obstructed and far-away objects. Even in smoke, harsh weather conditions, or at night â situ ...

Thalamic microcircuitry: neurons, synapses, and circuit motifs in receptive field structure and sensory processing

Jane Yi

Our perception of the world is first shaped by the thalamus, a structure composed of many nuclei in the center of our brains. Different nuclei hold different responsibilities - vision (dorsal lateral genicular nucleus; dLGN), audition (medial geniculate nu ...

Serial dependence does not originate from low-level visual processing

Michael Herzog, David Pascucci, Gizay Ceylan

Perception depends not only on the current sensory input but also on the preceding history of stimuli. In serial dependence (SD), for example, the orientation of a Gabor patch is mistakenly reported as more similar to previous trials than it actually is. T ...

Long-lasting feature integration

Leila Drissi Daoudi - Kleinbauer

In the classic model of vision, processing is local, feedforward and hierarchical. The first stages of the visual system are retinotopic, i.e., neighboring points in the outside world are mapped onto neighboring photoreceptors of the retina and this is pre ...

Optimal integration of intraneural somatosensory feedback with visual information: a single-case study

Silvestro Micera, Ivo Strauss, Giacomo Valle

Providing somatosensory feedback to amputees is a long-standing objective in prosthesis research. Recently, implantable neural interfaces have yielded promising results in this direction. There is now considerable evidence that the nervous system integrate ...

Indoor environment as a multi-sensory experience: visual and thermal factor interactions

Marilyne Andersen, Jan Wienold, Giorgia Chinazzo

In our daily lives we are exposed simultaneously to multiple sensory stimuli, such as visual, thermal, acoustic and olfactory. Experienced together, they shape our perception of the environment and determine our comfort. In indoor environments, stimuli are ...

Behavioural, modeling, and electrophysiological evidence for supramodality in human metacognition

Olaf Blanke, Nathan Quentin Faivre

Human metacognition, or the capacity to introspect on one's own mental states, has been mostly characterized through confidence reports in visual tasks. A pressing question is to what extent results from visual studies generalize to other domains. Answerin ...

Unconscious integration of multisensory bodily inputs in the peripersonal space shapes bodily self-consciousness

Olaf Blanke, Andrea Serino, Nathan Quentin Faivre, Roy Salomon

Recent studies have highlighted the role of multisensory integration as a key mechanism of self-consciousness. In particular, integration of bodily signals within the peripersonal space (PPS) underlies the experience of the self in a body we own (self-iden ...

Tissue-specific enhancer repression through molecular integration of cell signaling inputs

Bart Deplancke

Drosophila leg morphogenesis occurs under the control of a relatively well-known genetic cascade, which mobilizes both cell signaling pathways and tissue-specific transcription factors. However, their cross-regulatory interactions, deployed to refine leg p ...

Nonlinear Hebbian Learning as a Unifying Principle in Receptive Field Formation

Wulfram Gerstner

The development of sensory receptive fields has been modeled in the past by a variety of models including normative models such as sparse coding or independent component analysis and bottom-up models such as spike-timing dependent plasticity or the Bienen- ...

Multisensory effects on somatosensation: a trimodal visuo-vestibular-tactile interaction

Olaf Blanke, Bruno Herbelin, Mariia Kaliuzhna

Vestibular information about self-motion is combined with other sensory signals. Previous research described both visuo-vestibular and vestibular-tactile bilateral interactions, but the simultaneous interaction between all three sensory modalities has not ...

The two dimensions of the body representation in women suffering from Anorexia Nervosa

Andrea Serino

A core symptom of Anorexia Nervosa (AN) is a severe alteration of body representations. Evidence from somatoperception studies point to a generic disturbances of somatosensory components of body representations. Here we have investigated whether AN patient ...

Those are Your Legs: The Effect of Visuo-Spatial Viewpoint on Visuo-Tactile Integration and Body Ownership

Olaf Blanke, Polona Pozeg

Experiencing a body part as one's own, i.e., body ownership, depends on the integration of multisensory bodily signals (including visual, tactile, and proprioceptive information) with the visual top down signals from peripersonal space. Although it has bee ...

Activating the motor system through action observation: is this an efficient approach in adults and children?

Michela Bassolino

Observing an action performed by another person to learn a new movement is a frequent experience in adult daily life, such as in sports. However, it is an especially common circumstance during the development of motor skills in childhood. Studies on health ...

Crowding, grouping, and gain control in schizophrenia

Michael Herzog, Maya Roinishvili, Albulena Jashari-Shaqiri

isual paradigms are versatile tools to investigate the pathophysiology of schizophrenia. Contextual modulation refers to a class of paradigms where a target is flanked by neighbouring elements, which either deteriorate or facilitate target perception. It i ...

Visuo-vestibular mechanisms of bodily self-consciousness

Joachim Jean-Marie Forget

Bodily self-consciousness is linked to multisensory integration and is particularly dependent on vestibular perception providing the brain with the main sensory cues about body motion and location in space. Vestibular and visual inputs are permanently bala ...

Membrane potential correlates of sensory perception in mouse barrel cortex

Carl Petersen, Varun Sreenivasan, Yves Emile Alfred Kremer, Shankar Sachidhanandam, Alexandros Kyriakatos

Neocortical activity can evoke sensory percepts, but the cellular mechanisms remain poorly understood. We trained mice to detect single brief whisker stimuli and report perceived stimuli by licking to obtain a reward. Pharmacological inactivation and optog ...

Retinal and post-retinal contributions to the quantum efficiency of the human eye revealed by electrical neuroimaging

Enrico Pomarico

The retina is one of the best known quantum detectors with rods able to reliably respond to single photons. However, estimates on the number of photons eliciting conscious perception, based on signal detection theory, are systematically above these values ...

The Contributions of Sensory Dominance and Attentional Bias to Cross-modal Enhancement of Visual Cortex Excitability

Micah Murray

Approaching or looming sounds (L-sounds) have been shown to selectively increase visual cortex excitability [Romei, V., Murray, M. M., Cappe, C., & Thut, G. Preperceptual and stimulus-selective enhancement of low-level human visual cortex excitability by s ...
