A study funded by the SNSF looked at the brain activity of sleepwalkers. It helps us understand what determines the sleepwalkers’ level of consciousness during these episodes.

A team from the Centre hospitalier universitaire vaudois (CHUV) was able to trigger sleepwalking episodes in patients. The study, conducted by Francesca Siclari – a neurologist funded by the SNSF – measured the brain activity associated with this sleep disorder, which affects 2-3% of adults. The results show that dreams and particular sleep phases influence the degree of consciousness during the episodes. This work has been published in the journal Nature Communications (*).

Your first step towards scientific independence

Ambizione grants are aimed at early-career researchers who wish to conduct, manage and lead an independent project at a Swiss higher education institution. Afterwards, grantees have the opportunity to either continue on their academic path or transfer their skills outside academia.
