Two studies conducted at the Grenoble Institute of Neuroscience as part of Clarissa Baratin’s PhD research and published in Nature Communications show that our brain does not rely on exactly the same neural circuits to evaluate pleasant and unpleasant experiences, and that its activity immediately before a decision can influence our choices.

Doubting what we have seen, what we have done, or a decision we have just made: doubt is a prominent feature of obsessive-compulsive disorder (OCD). A study conducted at the Grenoble Institute of Neuroscience suggests that this doubt may not result from poorer visual perception, but could instead be linked to altered metacognition, the ability to evaluate one’s own perceptions.

A study conducted at the Grenoble Institute of Neuroscience shows, in a progressive macaque model of Parkinson’s disease, that activity in the subthalamic nucleus changes before the onset of motivational, cognitive and then motor impairments. These findings could pave the way for deep brain stimulation strategies better tailored to each patient’s symptoms.

À l’occasion de la Journée internationale des épilepsies, le 9 février 2026, plusieurs chercheurs et cliniciens étaient présents au CHU Grenoble Alpes pour échanger avec le public sur les chirurgies de l’épilepsie. Des interventions qui ont permis de souligner la contribution déterminante des patients dans l’avancée des connaissances sur le fonctionnement du cerveau humain.

Researchers at GIN and the University of Toronto confirm the efficacy and safety of magnetic resonance-guided focused ultrasound thalamotomy (MRgFUS) for treating essential tremor.

Two recent studies conducted by GIN researchers reveal new cognitive mechanisms involved in the often ‘silent’ dimensions of schizophrenia.

Treating sleep disorders associated with Parkinson's disease using deep brain stimulation will soon be possible, thanks to work carried out by Nathan Barbe under the supervision of Brigitte Piallat, a neuroscientist at GIN, and in collaboration with Fonds Clinatec and the CHUGA.

The impact of Parkinson's disease on the brainstem has so far been little studied. However, GIN researchers have just shown that some of its structures are able to reorganize themselves in Parkinsonian rats, providing evidence of specific neuroplasticity.

À la recherche d’un biomarqueur fiable du risque de schizophrénie, des chercheurs du GIN en collaboration avec leurs collègues de l’Université de Durham excluent la perception auditive.

Une étude menée par des chercheurs du GIN révèle ce qu’il se passe dans notre cerveau lorsque nous faisons un choix en prenant un risque économique
