The kinetochore: an unexpected player in neuronal connectivity
From July 16, 2026 to September 30, 2026
Essential for cell division, kinetochore proteins also play an unexpected role in mature neurons. While a US research team had observed their influence on dendritic spine formation, Leticia Peris’s expertise helped uncover the underlying mechanism: these proteins control microtubule dynamics within neurons.

Leigh syndrome: Ultrasound-assisted gene therapy, a promising strategy
On March 3, 2026
In a paper published in Brain, the team led by Michael Decressac succeeded in restoring the expression of the NDUFS4 gene in a mouse model of Leigh syndrome using ultrasound-assisted gene therapy. This innovative approach was associated with significant benefits in terms of survival and brain function in the treated animals.
A team from the Grenoble Institute of Neurosciences has developed an extremely simple, biomimetic artificial neural network capable of automatically identifying complex temporal patterns in multichannel neural signals. This original approach offers a solution for real-time processing of the massive data streams generated by next-generation neural interfaces.

X-ray microbeams to treat drug-resistant epilepsy: a promising proof of concept
On January 20, 2026
In a study published at the end of 2025 in the journal Epilepsia, a GIN research team shows, in a mouse model, that X-ray microbeams can significantly reduce epileptic activity while limiting side effects on surrounding brain tissue.
