Schaffer collateral axon
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 of the Papez circuit, and of the hippocampal trisynaptic loop. It is one of the most … 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 … 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 it is clear that Schaffer collaterals assist the activity-dependent plasticity and the information processes that are always … See more Transmitters are released from pre-synaptic terminals through fusion of vesicles to the membrane, that are filled with See more 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 … See more Plastic changes occurring in the hippocampus are involved in directing the process by which memories get stored.
