Final answer:
Low-frequency stimulation in the neural pathway entering the hippocampus leads to a decrease in the responsiveness of nerve cells to glutamate.
Step-by-step explanation:
Low-frequency stimulation in the neural pathway entering the hippocampus is likely to lead to a decrease in the responsiveness of nerve cells to glutamate. Glutamate is a neurotransmitter that plays a crucial role in learning and memory processes. When low-frequency stimulation occurs, AMPA receptors are removed from the membrane, which reduces the cell's ability to respond to glutamate. This can affect the ability to form new memories and learn new tasks.
