One of the fundamental processes by which memories are stored and learning takes place

involves two types of glutamate receptors

Explanation:

The glutamate receptors played the most crucial role in passing electrical signals from one neuron to another.

These signals are what we primarily used for memory formation, learning new information, and regulate the data that we input into several categories in our head. Because of this, we can sat that glutamate receptors are the place where fundamental processes by which memories are stored and learning takes place
