Schaffer collateral stimulation
WebThe invention relates to methods for treating depression, anxiety, and other related diseases by administering a peptide NMDAR partial agonist. Schaffer collateral synapses have been used as a sample synapse, a typical excitatory glutamatergic synapse in the cortex that has very well been studied in order to try to identify the rules of both the patterns of stimulation in electrical rules and the chemical mechanisms by which synapses get persistently … 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 Plastic changes occurring in the hippocampus are involved in directing the process by which memories get stored.
