Long-term depression通路
)
In neurophysiology, long-term depression (LTD) is an activity-dependent reduction in the efficacy of neuronal synapses lasting hours or longer following a long patterned stimulus. LTD occurs in many areas of the CNS with varying mechanisms depending upon brain region and developmental progress. As the … Ver mais LTD in the hippocampus and cerebellum have been the best characterized, but there are other brain areas in which mechanisms of LTD are understood. LTD has also been found to occur in different types of neurons … Ver mais It is highly important for neurons to maintain a variable range of neuronal output. If synapses were only reinforced by positive feedback, they would eventually come to the point of … Ver mais Hippocampus LTD affects hippocampal synapses between the Schaffer collaterals and the CA1 pyramidal cells. LTD at the Schaffer collateral-CA1 synapses depends on the timing and frequency of calcium influx. LTD occurs at these … Ver mais Long-term depression has long been hypothesized to be an important mechanism behind motor learning and memory. … Ver mais Long-term depression can be described as either homosynaptic plasticity or heterosynaptic plasticity. Homosynaptic LTD is restricted to … Ver mais Endocannabinoids affect long-lasting plasticity processes in various parts of the brain, serving both as regulators of pathways and … Ver mais Spike timing-dependent plasticity (STDP) refers to the timing of presynaptic and postsynaptic action potentials. STDP is a form of neuroplasticity in which a millisecond-scale … Ver mais WebLTP（Long-term Potential）的发现及其基本性质 在1973年，科学家Bliss和Lomo发现了在perforant pathway的LTP现象。 给一串高频率的强直刺激(tetanus)会导致长时间的Dentate Gyrus神经元的EPSP幅度增加。
