WebJun 20, 2005 · The molecular analysis of long-term plasticity in the mammalian brain has to confront the existence of multiple forms of plasticity, both at a single synapse and across distinct synapses ().Thus, whereas long-term potentiation (LTP) in its early phase (E-LTP) at the Schaffer collateral synapses between hippocampal CA3 and CA1 pyramidal neurons … WebSpike-timing-dependent (st) LTP was induced by pairing Schaffer collateral stimulation with antidromic stimulation of CA1 pyramidal neurons. Theta-burst-induced (tb) LTP was induced by theta-burst ...

WebAug 18, 2024 · Schaffer collateral stimulation-evoked EPSPs were recorded from the hippocampal CA1 area, while the animal was placed in a small (5 × 5×5 cm) box before (BL values) and after i.c.v. injections. Electrical stimuli to Schaffer collaterals were 100-μs-long, square, biphasic pulses delivered either alone, paired, or in trains. WebApr 11, 2024 · (A) Representative recordings showing fEPSPs upon the Schaffer collateral paired-pulse stimulations (10–20 µA, 0.1 ms, 40 ms apart). ( B ) The quantification of the fEPSP amplitude of the second stimulation relative to the first stimulation shows an increase in the paired-pulse ratio in the hippocampal slices from mice that are deficient in … WebThe stimulation consists of several trains of electric pulses separated by longer time intervals to allow the BOLD signal to recover to baseline levels.
