Con-G restores mitochondrial function in neurons with extrasynaptically-activated NMDARs. DIV 13–15 rat hippocampal neurons after activation of synaptic, extrasynaptic, or total NMDARs were untreated (C), or treated with 40 μM con-G (+G) or 40 μM con-T (+T), and analyzed for mitochondrial viability by staining live with Mitotracker Red. The neurons were fixed and then imaged. (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.)
