A neuron-glia signalling network in the active brain

Glial cells are active partners of neurons in processing information and sy naptic integration. They receive coded signals from synapses and elaborate modulatory responses. The active properties of glia, including long-range s ignalling and regulated transmitter release, are beginning to be elucidated . Recent insights suggest that the active brain should no longer be regarde d as a circuitry of neuronal contacts, but as an integrated network of inte ractive neurons and glia.
