Decoding electroencephalographic responses to visual stimuli compatible with electrical stimulation

Silvestro Micera, Simone Romeni, Laura Toni, Fiorenzo Artoni

Electrical stimulation of the visual nervous system could improve the quality of life of patients affected by acquired blindness by restoring some visual sensations, but requires careful optimization of stimulation parameters to produce useful perceptions. ...

Value Estimation versus Effort Mobilization: A General Dissociation between Ventromedial and Dorsomedial Prefrontal Cortex

Nicolas Clairis

Deciding on a course of action requires both an accurate estimation of option values and the right amount of effort invested in deliberation to reach suf fi cient con fi dence in the fi nal choice. In a previous study, we have provided evidence, across a s ...

Inter-Individual Variability of Human Thermoregulation: Towards Personalized Ergonomics of the Indoor Thermal Environment

Dolaana Khovalyg

Indoor temperature maintenance represents a large portion of the energy used in buildings and reducing dependence on energy-intensive thermal conditioning systems would benefit our fight against climate change as well as potentially have positive effects o ...

Brain functional connectivity dynamics at rest in the aftermath of affective and cognitive challenges

Dimitri Nestor Alice Van De Ville, Thomas William Arthur Bolton, Gwladys Rey, Julian Gaviria

Carry-over effects on brain states have been reported following emotional and cognitive events, persisting even during subsequent rest. Here, we investigated such effects by identifying recurring co-activation patterns (CAPs) in neural networks at rest wit ...

Peri-personal space encoding in patients with disorders of consciousness and cognitive-motor dissociation

José del Rocio Millán Ruiz, Andrea Serino, Maria Manuela da Silva Marques, Serafeim Perdikis, Jean-Paul Noel

Behavioral assessments of consciousness based on overt command following cannot differentiate patients with disorders of consciousness (DOC) from those who demonstrate a dissociation between intent/awareness and motor capacity: cognitive motor dissociation ...

Brain-Controlled Devices: The Perception-Action Closed Loop

José del Rocio Millán Ruiz

Future neuroprosthetics will be tightly coupled with the user in such a way that the resulting system can replace and restore impaired upper limb functions because controlled by the same neural signals than their natural counterparts. However, robust and n ...

Fluctuations of spontaneous EEG topographies predict disease state in relapsing-remitting multiple sclerosis

Dimitri Nestor Alice Van De Ville

Spontaneous fluctuations of neuronal activity in large-scale distributed networks are a hallmark of the resting brain. In relapsing-remitting multiple sclerosis (RRMS) several fMRI studies have suggested altered resting-state connectivity patterns. Topogra ...

Visual Feedback Dominates the Sense of Agency for Brain-Machine Actions

Olaf Blanke, Aaron Schurger, Nathaniel Evans, Steven Gale

Recent advances in neuroscience and engineering have led to the development of technologies that permit the control of external devices through real-time decoding of brain activity (brain-machine interfaces; BMI). Though the feeling of controlling bodily m ...

Increased intra-participant variability in schizophrenia: evidence from single-trial EEG analysis

Michael Herzog, Patricia Figueiredo, Janir Nuno Ramos Antunes Da Cruz

Visual deficits in schizophrenic patients are of particular interest because they reflect the deficient circuits of information processing in the brain. In our previous work, we showed that schizophrenic patients have decreased peak amplitudes and reduced ...

Implicit emotional tagging of multimedia using EEG signals and brain computer interface

Touradj Ebrahimi, Jong Seok Lee, Ashkan Yazdani

In multimedia content sharing social networks, tags assigned to content play an important role in search and retrieval. In other words, by annotating multimedia content, users can associate a word or a phrase (tag) with that resource such that it can be se ...
