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.

The role of the inferior parietal lobule in writer's cramp

Traian Popa

Humans have a distinguishing ability for fine motor control that is subserved by a highly evolved cortico-motor neuronal network. The acquisition of a particular motor skill involves a long series of practice movements, trial and error, adjustment and refi ...

TASH: Toolbox for the Automated Segmentation of Heschl's gyrus

Dimitri Nestor Alice Van De Ville

Auditory cortex volume and shape differences have been observed in the context of phonetic learning, musicianship and dyslexia. Heschl's gyrus, which includes primary auditory cortex, displays large anatomical variability across individuals and hemispheres ...

Functional magnetic resonance imaging provides rich spatio-temporal data of human brain activity during task and rest. Many recent efforts have focussed on characterising dynamics of brain activity. One notable instance is co-activation pattern (CAP) analy ...

Creating a neuroprosthesis for active tactile exploration of textures

Solaiman Shokur, Miguel Nicolelis

Intracortical microstimulation (ICMS) of the primary somatosensory cortex (S1) can produce percepts that mimic somatic sensation and, thus, has potential as an approach to sensorize prosthetic limbs. However, it is not known whether ICMS could recreate act ...

Combined rehabilitation promotes recovery of motor functionality in a mouse model of stroke

Silvestro Micera, Maria Pasquini

Neuro-rehabilitative research is developing novel strategies to enhance the effectiveness of therapies after stroke by using a combination of physical and plasticizing treatments 1-3. Previous studies have shown that repeated optogenetics stimulation of ne ...

A Derived Positional Mapping of Inhibitory Subtypes in the Somatosensory Cortex

Henry Markram, Daniel Keller, Olivier Burri, Romain Guiet, Julie Meystre, Rahul Valiya Veettil

Obtaining a catalog of cell types is a fundamental building block for understanding the brain. The ideal classification of cell-types is based on the profile of molecules expressed by a cell, in particular, the profile of genes expressed. One strategy is, ...

Background When single pulse transcranial magnetic stimulation (TMS) is applied over the primary motor cortex (M1) with sufficient intensity, it evokes muscular contractions (motor-evoked potentials, MEPs) and muscle twitches (TMS-evoked movements). Partic ...

Surface-based characteristics of the cerebellar cortex visualized with ultra-high field MRI

Wietske Van der Zwaag, Cristina Granziera, Guillaume Bonnier, Mario Joao Fartaria de Oliveira, Kieran O'Brien, Yohan Boillat

Although having a relatively homogeneous cytoarchitectonic organization, the cerebellar cortex is a heterogeneous region characterized by different amounts of myelin, iron and protein expression profiles. In this study, we used quantitative T1 and T2* mapp ...

Cardio-visual full body illusion alters bodily self-consciousness and tactile processing in somatosensory cortex

Olaf Blanke, Bruno Herbelin, Jane Aspell, Lukas Heydrich

Prominent theories highlight the importance of bodily perception for self-consciousness, but it is currently not known whether this is based on interoceptive or exteroceptive signals or on integrated signals from these anatomically distinct systems, nor wh ...

Introduction Unilateral movements are primarily processed in contralateral cortical and subcortical areas and additionally in ipsilateral cerebellum, leading to an asymmetric pattern of neural activation. Decrease of lateralization is characteristic of agi ...
