The brain function is modulated by both rapid electrochemical activity of neurons and slow structural remodeling of synapses. Despite remarkable progress in controlling neural activity, methods for structural modulation of synaptic connections are still scarce. Here, we present a synthetic approach for synapse elimination via engineering of direct neuro-glial interactions which result in the uptake of synaptic components by astrocytes. The size-dependent synapse elimination in the CA3-CA1 circuit leads to a decline in synaptic connectivity, while the remaining synapses undergo reorganization o
