WebApr 4, 2024 · Long-term potentiation (LTP) was induced by high-frequency stimulation (100 Hz for 1 s) in hippocampal synapses; 102 in the PFC, LTP was induced by delivering a train of 100 Hz (50 pulses, 0.5 s duration) for a priming effect, which was 15 min later followed by four trains of 100 Hz (50 pulses, 0.5 s duration, 1 every 10 s). 103 LTP magnitude ... WebSep 17, 1999 · Induction of long-term synaptic changes at one synapse can facilitate the induction of long-term plasticity at another synapse. Evidence is presented here that if Aplysia sensory neuron somata and their remote motor neuron synapses are simultaneously exposed to serotonin pulses insufficient to induce long-term facilitation (LTF) at either …
Weblasted 10 min to allow efficient blockade of post-synaptic NMDARs by MK801. Two pulses with an interpulse interval of 33 msec (30 Hz) (Brasier and Feldman 2008) were administered at a frequency of 0.1 Hz for recordings of paired-pulse ratio of AMPA-EPSCs. Cells with a latency of 2–5 msec for the first EPSC WebSep 19, 2024 · Synaptic responses were analyzed with respect to the readily releasable pool (RRP) size, release probability (Pr), paired-pulse ratio (PPR), replenishment rate, and synaptic depression. Loss of TRPC channels significantly reduced the amplitude of the first EPSC during the train ( Fig 1A, 1B and 1D ) and clearly accelerated the time course of synaptic …
WebNov 3, 2024 · Here, only single-pulse stimuli and bursts with two pulses led to a reduction of the mean weight whereas more pulses per bursts led to a strengthening of synapses. Thus, periodic stimulation may either lead to a down-regulation of all (intra-population) synapses or to an up-regulation of all (intra-population) synapses, depending on the shape of … WebApr 11, 2024 · To test for glutamate impairment, we first analyzed paired pulse facilitation (PPF), a form of short-term synaptic plasticity sensitive to changes in release probability. …
