Research on information processing in the brain previously focused mainly on communication between neurons. However, in recent years it has emerged that a non-neuronal cell, the astrocyte, which was previously seen as a kind of support cell of your brain, also plays a role in memory and cognition. Astrocytes do this by forming connections with both neurons and blood vessels in the brain. Which molecules are involved in these connections is largely unknown. In SUPERGLUE we use advanced techniques to map these molecules and cellular interactions, taking an important step in our understanding of information processing by the brain.
