Spatial segregation of neuronal calcium signals encodes different forms of LTP in rat hippocampus
Calcium regulates numerous processes in the brain. How one signal can coordinate so many diverse actions, even within the same neurone, is the subject of intense investigation. Here we have used two-photon calcium imaging to determine the mechanism that enables calcium selectively and appropriately induce different forms of long-term potentiation (LTP) in rat hippocampus. Short-lasting LTP (LTP 1) required activation of ryanodine receptors (RyRs), which selectively increased calcium in synaptic...[Show more]
