Synaptic transmission and its plasticity are occurring in an environment that contains neurons but also glial cells and Synaptic transmission and its plasticity are occurring in an environment that contains neurons but also glial cells and extracellular matrix. How this interaction of neurons and astroglia, an abundant subtype of glial cells, determines hippocampal network function is what our research primarily focuses on. Building on our observations of neuron-astroglia interactions in healthy tissue we also explore how disease alters communication between these cell types.
What are we offering?
Expertise on functional and structural neuron-astrocyte interactions and their role in hippocampal physiology and hippocampus-dependent behaviours.
What are we interested in for collaboration?
Analysis of complex behaviours and fiber optometry.
