title: Synaptic homeostasis on the fast track.
abstract: Synaptic homeostasis is a phenomenon that prevents the nervous system from descending into chaos. In this issue of Neuron, Frank et al. overturn the notion that synaptic homeostasis at Drosophila NMJs is a slow developmental process. They report that postsynaptic changes are offset within minutes by a homeostatic increase in neurotransmitter release that requires the presynaptic Ca(2+) channel Cacophony.
