Although the contribution of Ca 2 buffering systems can vary between neuronal types and cellular compartments, it is unknown whether distinct Ca 2 sources within a neuron have different buffers. As individual Ca 2 sources can have separate functions, we propose that each is handled by unique systems. Using Aplysia californica bag cell neurons, which(More)
Although the contribution of Ca(2+) buffering systems can vary between neuronal types and cellular compartments, it is unknown whether distinct Ca(2+) sources within a neuron have different buffers. As individual Ca(2+) sources can have separate functions, we propose that each is handled by unique systems. Using Aplysia californica bag cell neurons, which(More)
High-resolution coreand valence-level photoemission spectra of Nb-doped TiO2 ceramics (Ti12xNbxO2 with 0.01,x,0.8) have been measured using monochromatic x-ray excitation. Nb doping produces a welldefined photoemission peak in the bulk band gap of rutile, whose intensity increases with increasing doping level. Core-level spectroscopy shows that the Nb is(More)
After Ca(2+) influx, mitochondria can sequester Ca(2+) and subsequently release it back into the cytosol. This form of Ca(2+)-induced Ca(2+) release (CICR) prolongs Ca(2+) signaling and can potentially mediate activity-dependent plasticity. As Ca(2+) is required for its subsequent release, Ca(2+) removal systems, like the plasma membrane Ca(2+)-ATPase(More)
