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. The entorhinal cortex sends the main input to the dentate gyrus (perforant … See more Schaffer collaterals are axon collaterals given off by CA3 pyramidal cells in the hippocampus. These collaterals project to area CA1 of the hippocampus and are an integral part of memory formation and the emotional network … See more Throughout the memory process in the hippocampus, Schaffer collaterals seem not to play a major role in the formation of actual memory, but … See more Transmitters are released from pre-synaptic terminals through fusion of vesicles to the membrane, that are filled with See more The functional hippocampus stores long-term memories through synaptic plasticity in terms of storing information. The hippocampus in communication with the neocortex mediates memory degradation. Plastic changes occurring in the hippocampus are … See more Plastic changes occurring in the hippocampus are involved in directing the process by which memories get stored.

WebJun 22, 2024 · Basal synaptic transmission at the Schaffer collateral-CA1 synapses was first evaluated by measuring input–output curves using 12 stimuli (constant current pulses from 10 to 120 μA in increments of 10 μA, duration of 40 μs). To measure the paired-pulse facilitation (PPF) response, ... WebAug 21, 2015 · I used extracellular recordings of the schaffer collateral response to field stimulation to verify synaptic activation, ... We outline the utility of this protocol for the 3D reconstruction of a recycling vesicle pool in CA3-CA1 synapses from an acute hippocampal slice and for the characterization of its anatomically defined docked pool. child convulsions with fever
