Suppose my consciousness is localized in a single neuron. This neuron is connected to thousands of other neurons, each of which is connected to... etc, so the "me"-cell indirectly receives inputs from the entire body. The swapping of attention, as well as any other effect you can think of, could conceivably be implemented by a "me"-cell alone, just based on the interplay of inputs.
