Abstract

Role of astrocytes in learning and memory The role of astrocytes in synaptic plasticity has remained controversial. It has been suggested that astrocytes, the star-shaped glial cells found in the brain and spinal cord that were once considered merely passive support cells, are involved in inducing LTP (long-term potentiation) of synaptic transmission — a model for the mechanisms of memory — via the modulation of NMDA-receptor activation and postsynaptic Ca2+ entry. A new study provides more support for that theory by demonstrating that the inhibition of d-serine release from individual astrocytes blocks the potentiation of many nearby neuronal junctions.
