The research group GliaLab explores functions of astrocytes, the starshaped glial cells, in the healthy brain, sleep and in neurological disorders.

Our current research focuses on the interaction between glial cells, neurons and the blood vessels in the brain in physiology, in sleep, and in various neurological disorders. Understanding neuronal-glial-vascular interactions may provide new treatment strategies for a range of brain disorders with ion and water dyshomeostasis, including migraine, epilepsy and Alzheimer's disease.
Our main methods are in vivo and in vitro two-photon microscopy in combination with genetically encoded fluorescent sensors and electrophysiology. Two-photon microscopy offers real-time imaging of physiological and pathophysiological processes in the brain of living animals. Through a cranial window we study the activity of neurons and astrocytes, brain waste clearance and cerebral blood flow in awake and sleeping mice.
