WebLong-term potentiation (LTP) is a persistent increase in synaptic strength following high-frequency stimulation of a chemical synapse. Studies of LTP are often carried out in slices of the hippocampus, an important organ for learning and memory. In such studies, electrical recordings are made from cells and plotted in a graph such as this one. Web11 de abr. de 2024 · Because Cx30 regulates synaptic efficacy, we then investigated its involvement in long-term synaptic plasticity. Following tetanic stimulation of Schaffer collaterals, we found that the amplitude of long-term potentiation (LTP) was significantly reduced (approximately 60%) in mice expressing increased levels of astroglial Cx30 .
