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.
A major discovery made at GIN, which opens up new avenues for understanding the long-term side effects of this essential treatment.

Bipolar disorder: distinct brain activity even during stable mood states
On November 7, 2025
An international team of researchers has shown that the brains of people with bipolar disorder do not process emotional information in quite the same way as those of individuals without psychiatric disorders – including when their mood is stable and no clear symptoms are visible.
Conscience
How and when does the brain transform a fleeting image into conscious perception?
On October 24, 2025
An international team of researchers has recently demonstrated that our cortex accumulates the sensory information necessary for consciousness even when no response is required. These findings, published in Nature Communications, shed new light on the neural basis of perceptual consciousness.
