Temporal dynamics of intranasal oxytocin in human brain electrophysiology

Patricia Figueiredo, Janir Nuno Ramos Antunes Da Cruz

Oxytocin (OT) is a key modulator of human social cognition, popular in behavioral neuroscience. To adequately design and interpret intranasal OT (IN-OT) research, it is crucial to know for how long it affects human brain function once administered. However ...

Gene replacement therapy provides benefit in an adult mouse model of Leigh syndrome

Johan Auwerx

Mutations in nuclear-encoded mitochondrial genes are responsible for a broad spectrum of disorders among which Leigh syndrome is the most common in infancy. No effective therapies are available for this severe disease mainly because of the limited capabili ...

TMS-induced control of bodily self-consciousness by combining non-invasive brain stimulation and immersive virtual reality

Matteo Franza

Our brain constantly receives and integrates a flow of sensory and motor information that shapes the way our body is represented. Several experimental approaches have been proposed to alter the body representation, by manipulating exteroceptive or interoce ...

Nutritional Ketosis Increases NAD+/NADH Ratio in Healthy Human Brain: An in Vivo Study by 31P-MRS

Rolf Gruetter, Lijing Xin, Özlem Ipek, Mojgan Masoodi, Nicolas Christinat, Maya Shevlyakova

Ketones represent an important alternative fuel for the brain under glucose hypo-metabolic conditions induced by neurological diseases or aging, however their metabolic consequences in healthy brains remain unclear. Here we report that ketones can increase ...

Non-invasive brain stimulation of motor cortex induces embodiment when integrated with virtual reality feedback

Olaf Blanke, Andrea Serino, Marco Solcà, Javier Bello Ruiz, Matteo Franza, Thomas Schmidlin, Mattia Pinardi, Marianne Anke Stephan

Previous evidence highlighted the multisensory-motor origin of embodiment - that is, the experience of having a body and of being in control of it - and the possibility of experimentally manipulating it. For instance, an illusory feeling of embodiment towa ...

Large eddy simulations for blood dynamics in realistic stenotic carotids

Alfio Quarteroni, Christian Vergara

In this paper, we consider large eddy simulations (LES) for human stenotic carotids in presence of atheromasic plaque, a pathological condition where transitional effects to turbulence may occur, with relevant clinical implications such as plaque rupture. ...

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 ...

Characterizing the connectome in schizophrenia with diffusion spectrum imaging

Jean-Philippe Thiran, Alessandra Griffa, Kim Do, Patric Hagmann

Schizophrenia is a complex psychiatric disorder characterized by disabling symptoms and cognitive deficit. Recent neuroimaging findings suggest that large parts of the brain are affected by the disease, and that the capacity of functional integration betwe ...

Somatic and axonal LIGHT signaling elicit degenerative and regenerative responses in motoneurons, respectively

Julianne Bobela

A receptor-ligand interaction can evoke a broad range of biological activities in different cell types depending on receptor identity and cell type-specific post-receptor signaling intermediates. Here, we show that the TNF family member LIGHT, known to act ...

Predicting Subjective Sensation of Reality During Multimedia Consumption Based on EEG and Peripheral Physiological Signals

Touradj Ebrahimi, Philippe Hanhart, Martin Rerabek, Jong Seok Lee, Eleni Kroupi

Sensation of reality refers to the ability of users to feel present in a multimedia experience. As 3D technologies target to provide more immersive and higher quality multimedia experiences, it is important to understand Quality of Experience (QoE) and sen ...

Emotion Detection and Recognition based on Brain and Peripheral Physiological Signals

Eleni Kroupi

Emotions affect and determine social relationships and interactions, memory and creativity, and influence the mechanisms of rational thinking and decision making. The influence of emotion on decision making has gained attention in computer science. By d ...

Brain-Computer Interface in Multimedia Systems

Ashkan Yazdani

A brain-computer interface (BCI) is a system that allows a user to communicate with the environment only through cerebral activity, without using muscular output channels. To establish a direct link between the brain and a computer, the electroencephalogra ...
