Expectation effects on repetition suppression in nociception Open
We show that repetition suppression (RS; the diminished neural activity upon repeated stimulus presentation) can be observed in the nociceptive domain: brief laser stimuli lead to RS in event-related potentials and gamma oscillations. Impo…

Evaluating cardiac noise correction approaches for non-invasive electrophysiology of the human spinal cord Open
The spinal cord is an important component of the central nervous system for the processing of sensorimotor information transmitted between the body and the brain. Electrospinography (ESG) is the most accessible non-invasive technique for r…

Somatosensory high frequency oscillations across the human central nervous system Open
Information transmission in the central nervous system (CNS) relies on the propagation of action potentials (neuronal spikes), traditionally thought to be inaccessible with electroencephalography (EEG). Converging evidence from human and a…

A multichannel electrophysiological approach to noninvasively and precisely record human spinal cord activity Open
The spinal cord is of fundamental importance for integrative processing in brain–body communication, yet routine noninvasive recordings in humans are hindered by vast methodological challenges. Here, we overcome these challenges by develop…

Cortical response variability is driven by local excitability changes with somatotopic organization Open
Identical sensory stimuli can lead to different neural responses depending on the instantaneous brain state. Specifically, neural excitability in sensory areas may shape the brain’s response already from earliest cortical processing onward…

Manipulating the Perceived Shape and Color of a Virtual Limb Can Modulate Pain Responses Open
Changes in body representation may affect pain perception. The effect of a distorted body image, such as the telescoping effect in amputee patients, on pain perception, is unclear. This study aimed to investigate whether distorting an embo…

Agency and responsibility over virtual movements controlled through different paradigms of brain−computer interface Open
Key points Embodiment of a virtual body was induced and its movements were controlled by two different brain−computer interface (BCI) paradigms – one based on signals from sensorimotor versus one from visual cortical areas. BCI‐control of …

Agency and responsibility over virtual movements controlled through different paradigms of brain–computer interface Open
Agency is the attribution of an action to the self and is a prerequisite for experiencing responsibility over its consequences. Here we investigated agency and responsibility by studying the control of movements of an embodied avatar, via …

Mimicking Schizophrenia: Reducing P300b by Minimally Fragmenting Healthy Participants’ Selves Using Immersive Virtual Reality Embodiment Open
The most robust and clear biological index differentiating persons with schizophrenia from healthy controls is the drastic reduction of the amplitude of their P300b event-related brain potential (ERP). However, the cause of that reduction …

Multisensory processing and agency in vr embodiment: interactions through bci and their therapeutic applications Open
Body ownership refers to the experience that this body is my body and is closely linked to consciousness. Multisensory integration processes play an important role in body ownership as shown in the rubber hand illusion, which induces the i…

Seeing an Embodied Virtual Hand is Analgesic Contingent on Colocation Open
Looking at a virtual body has analgesic properties similar to looking at one's real body. We identify the importance of colocation between a real and a surrogate body for this to occur and thereby resolve a scientific controversy. This inf…
