Neuronal Receptors (s) having The way that different parts of a neuron carry out multiple information processing roles is illustrated by the CA1 pyramidal cell in the hippocampus. The authors used 2-photon microscopy to obtain high resolution images of calcium signals in the apical dendrites while activating Schaffer collateral inputs to induce long-term potentiation (LTP) of different durations. Short-duration LTP (LTP 1) was associated with Ca increase in dendritic spines, due to activation of NMDA receptors and local ryanodine receptors (RyRs). Intermediate duration LTP (LTP 2) was associated with Ca increase in dendritic branches, due to activation of NMDA receptors and local IP3 receptors (IP3Rs). For Ca increase in long duration LTP (LTP3), see Ca channels in CA1 pyramidal cell apical dendrite. ... as Publication facts
