Stavsky et al. examined the effects of deleting the mitochondrial sodium/lithium/calcium exchanger, NCLX, on mitochondrial and synaptic calcium homeostasis, synaptic activity, and plasticity in mice. Having identified a human mutation that impairs NCLX activity and is associated with mental retardation, they show that NCLX is crucial for defining synaptic strength and plasticity, which are pivotal elements of learning and memory.
