Question

Quizplus · Accepted Answer

Intense electrical stimulation of axons within the hippocampal formation results in long-term potentiation of postsynaptic neurons. Long-term potentiation (LTP) is a persistent strengthening of synaptic connections between neurons that can involve changes in the number or sensitivity of receptors at the synapse, alterations in cellular signaling pathways, and other mechanisms. LTP is thought to play a key role in learning and memory, and has been extensively studied in the hippocampus. By contrast, axoaxonic inhibition, recurrent inhibition, long-term potentiation of presynaptic neurons, and conditioned taste aversion are all distinct concepts that are not directly related to the effects of electrical stimulation on hippocampal axons.
