Caption

A represents a 3D electron microscopy analysis of glial phagocytosis. In the brain, presynaptic bouton (blue) sends information to the postsynaptic spine (yellow). Such synaptic contact is surrounded by the glia (magenta). With learning and memory, part of the spine is eaten by the glia (phagocytosis). B shows a 3D reconstruction of the postsynaptic spine. The protrusion (orange) is the part being eaten by the surrounding glia. The reduction in the spine volume leads to efficient motor control.
