Graph Chatbot

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.

Apraxia: a review

Olaf Blanke, Aude Billard, Biljana Petreska von Ritter-Zahony

Praxic functions are frequently altered following brain lesion, giving rise to apraxia - a complex pattern of impairments that is difficult to assess or interpret. In this chapter, we review the current taxonomies of apraxia and related cognitive and neuro ...

A system for automatic on-line time detection and classification of neural spikes based on a digital signal processor and a FPGA controller

Diego Ghezzi

Definition of single spikes from multiunit spike trains plays a critical role in neurophysiology and in neuroengineering as it does the question of how much information is encoded by single neurons in a neuronal network. Moreover, the possibility to develo ...

Atrial fibrillatory cycle length: computer simulation and potential clinical importance

Vincent Jacquemet, Lam Dang

Aims Atrial fibrillatory cycle length (AFCL) is generally accepted as a surrogate marker for local refractoriness. In this study, a computer model and clinical data on human subjects undergoing catheter ablation for paroxysmal and persistent AF were used t ...

Removing Ocular Artifacts from EEG Signals Using Adaptive Filtering and ARMAX Modeling

Gelareh Mohammadi

EEG signal is one of the oldest measures of brain activity that has been used vastly for clinical diagnoses and biomedical researches. However, EEG signals are highly contaminated with various artifacts, both from the subject and from equipment interferenc ...

Evoking spontaneous activity

Carl Petersen

In this issue of Neuron, MacLean et al. report that thalamic stimulation can evoke spatiotemporal sequences of neocortical neuronal activity similar to spontaneous UP states. This could suggest that the patterns of activity associated with the processing o ...

Phase synchronization for classification of spontaneous EEG signals in brain-computer interfaces

Elly Gysels

By directly analyzing brain activity, Brain-Computer Interfaces (BCIs) allow for communication that does not rely on any muscular control and therefore constitute a possible communication channel for the completely paralyzed. Typically, the user performs d ...

EEG pattern recognition through multi-stream evidence combination

EEG recordings provide an important means of brain-computer communication, but their classification accuracy is limited by unforeseeable variations in the signal due to artefacts or recogniser-subject feedback. A number of techniques were recently develope ...

Functional MRI with simultaneous EEG recording: feasibility and application to motor and visual activation

Olaf Blanke

The possibility of combining the high spatial resolution of functional magnetic resonance imaging (fMRI) with the high temporal resolution of electroencephalography (EEG) may provide a new tool in cognitive neurophysiology, as well as in clinical applicati ...

Neurophysiological distinction of verb categories

Friedhelm Christoph Hummel

Neurophysiological brain responses to subcategories of action verbs were recorded using high resolution EEG. Starting 240 ms after word onset, topographies of event-related potentials distinguished between verbs referring to different action types. Current ...
