[Neuroscience News – July 18, 2025] –
Summary: The brain remains highly active during sleep, and mapping this activity can reveal early signs of neurological and sleep disorders. Using rare intracranial EEG data, researchers refined methods to distinguish functional areas of the cerebral cortex based on their unique electrical activity, even at rest.
These findings highlight how precise cortical mapping could enable earlier diagnoses of conditions like Alzheimer’s, epilepsy, and sleep disorders. Such advances may also pave the way for more personalized and targeted neurological therapies.
Key Facts:
- Cortical Mapping Advances: Researchers identified distinct activity patterns in cortical regions during sleep.
- Clinical Promise: This work may aid early detection of neurodegenerative and sleep disorders.
- New Methods: Computational tools refined how electrical signals parcel the brain’s functional areas.

“Complex processes are going on in the brain when we sleep,” says Dr Karolina Armonaitė, a neuroscientist from Kaunas University of Technology, Lithuania.
According to her, a more precise understanding of what happens in different areas of the cerebral cortex during sleep can help diagnose sleep disorders and neurological diseases more accurately.
