Laboratory description

We fovcused our investigations on the role of astrocytes in sleep regulation throughout their involvement in energy metabolism.
We mainly used models of sleep deprivation/ fragmentation in mice.
We also used biosensors for brain metabolites measurements.

Technical Capabilities and areas of expertise

In animals: polygraphic sleep recording, telemetric recordings of locomotor and body temperature rhythms, in vivo biosensors, qPCR
