Chattez avec Graph Search
Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Our comprehension of human brain functions and their dynamics has been dramatically improved by recent developments in non-invasive imaging techniques. These methods can be divided into two different categories, according to the nature of the measured sign ...
This study aims to characterize the EEG correlates of exploratory behavior. Decision making in an uncertain environment raises a conflict between two opposing needs: gathering information about the environment and exploiting this knowledge in order to opti ...
The most general and striking evidence related with brain injury is that of the restoration of function. Recovery of motor and somatosensory functions has shown to commonly occur after stroke, but not all individuals show improvement. Clinical studies have ...
This abstract addresses the question of human imitation through convergent evidence from neuroscience. We look at deficits in imitation following brain lesion, such as apraxia. We believe that looking at how imitation is impaired can unveil its underlying ...
Since almost two decades, a considerable amount of work has been devoted to the accurate delineation of normal and abnormal brain development, using cerebral MRI. In the broad field of neuroimaging research, specific genetic conditions associated with impa ...
Whether different brain networks are involved in generating unimanual responses to a simple visual stimulus presented in the ipsilateral versus contralateral hemifield remains a controversial issue. Visuo-motor routing was investigated with event-related f ...
Stimulation of a site on the brain's left hemisphere prompts the creepy feeling that somebody is close by. The strange sensation that somebody is nearby when no one is actually present has been described by psychiatric and neurological patients, as well as ...
In vivo 1H NMR spectroscopy at 7 T was utilized to measure the changes in lactate concentration upon repeated identical visual stimuli, each lasting for 2 min. The average amplitude of these increases was found to be reduced over time (P < 0.01), from 0.13 ...
Real-time acquisition of electromyography (EMG) during functional Magnetic Resonance Imaging (fMRI) provides a novel method of controlling motor experiments in the scanner using feedback of EMG. Due to the redundancy in the human muscle system this is not ...
Development of technologies in the field of neuroimaging brought an increase interest in the quantification of cortical folding (gyrification), notably for neurogenetic and psychiatric disorders that may result from an early abnormal cortical development. ...
