Homeostatic plasticity functions within the nervous system to maintain normal neural functions, such as neurotransmission, within predefined optimal ranges. The defined output of these neuronal processes is referred to as the set point, which is the value that the homeostatic system defends against fluctuations. Currently, it is unknown how stable(More)
Synaptic dysfunction is considered the primary substrate for the functional declines observed within the nervous system during age-related neurodegenerative disease. Dietary restriction (DR), which extends lifespan in numerous species, has been shown to have beneficial effects on many neurodegenerative disease models. Existing data sets suggest that the(More)
The accumulation of oxidative damage is strongly linked to age-dependent declines in cell function, but the contribution of oxidative damage to morbidity is still debated. Many organisms seem to tolerate oxidative damage, and the extension of health span and life span by augmenting antioxidant activity has been inconsistent. Here we use the Drosophila model(More)
Altered insulin signaling has been linked to widespread nervous system dysfunction including cognitive dysfunction, neuropathy and susceptibility to neurodegenerative disease. However, knowledge of the cellular mechanisms underlying the effects of insulin on neuronal function is incomplete. Here, we show that cell autonomous insulin signaling within the(More)
Leber's Hereditary Optic Neuropathy (LHON) is a neurodegenerative mitochondrial disease characterized by retinal ganglionic cell death and eventual loss of central vision. Specific mtDNA mutations in respiratory complex I subunits (ND4/ND6/ND1) coding genes have been identified in most of LHON patients, and these mutations have been shown to cause(More)
