About half of the cells in the human brain are not neurons. Our aim is to understand their contribution and particularly of cortical astrocytes and Bergmann glia of the cerebellum to brain metabolism and signaling. We focus on how ion channels, transporters and organelles of the glial perisynaptic processes ensheathing neuro-nal synapses contribute to shaping and modulating synaptic transmission.
