How does an amoeba feel?

Can anyone help me, a layman, with this one? Higher animals have a
nervous system that enables them to feel. It is made up of thousands
of cells. But an amoeba, which is only a single-cell animal, can be
trained to avoid light, flee the point of a pin, etc. showing that it
has something analogous to memory and can feel pain. Yet the cell has
no"nervous system" inside it. Can you explain how this is possible?
