Unilateral whisker lesioning at age P4 leads to removal of thalamocortical synapses in layer IV of the barrel cortex over the course of the next 6 days. Synapse removal is mediated by microglia and induced by CX3CL1-CX3CR1 signaling between neurons and microglia. Downstream of CX3CL1-CX3CR1 activati...
