Schaffer collateral-ca1 synapses
WebSchaffer collaterals are axon collaterals given off by CA3 pyramidal cells in the hippocampus. These collaterals project to area CA1 of the hippocampus[1] and are an integral part of memory formation and the emotional network of the Papez circuit, and of the hippocampal trisynaptic loop. It is one of the most studied synapses in the world and … WebYou are studying chemical synaptic transmission at excitatory Schaffer Collateral synapses onto CA1 pyramidal cells in hippocampal slices in vitro.When you stimulate presynaptic Schaffer Collateral axons with an extracellular stimulating electrode, you observe postsynaptic inward currents in a CA1 pyramidal cell that you have in a whole-cell voltage …

In agreement with the loss of inhibitory perisomatic synapses, we found that Schaffer collateral feedforward inhibition but not excitation was impaired in CA2 pyramidal neurons and accompanied by ...
WebJan 1, 2024 · Accordingly, we investigated the effects of IMPX977 on synaptic transmission of Schaffer-CA1 pathway in acute hippocampal slices, the Schaffer collateral is located … WebBoth immunochemical and electrophysiological studies have confirmed that most Schaffer collateral-CA1 synapses are AMPAR-silent from the first postnatal day onward; however, these synapses become practically absent from the third week of development [6,22,29,30].
WebAt the synaptic level, long-term potentiation (LTP) of synaptic excitation and inhibition was induced in CA1 region by high frequency simulation (HFS) applied to Schaffer collaterals. Aβ25–35 was found to alter metaplastic mechanisms of plasticity, facilitating long-term depression (LTD) of both types of LTP. The Schaffer collateral is located between the CA3 region and CA1 region in the hippocampus. Schaffer collaterals are the axons of pyramidal cells that connect two neurons (CA3 and CA1) and transfer information from CA3 to CA1.
