In the Papez circuit of the limbic system, between which combination is the hypothalamus placed on the basis of function?

The concept of circuits of neuronal systems within the limbic system is best illustrated by the "Papez circuit." In order, beginning with the cingulate coex, neuronal communication proceeds as follows: the cingulate coex projects to the parahippocampal gyrus; which projects to the hippocampus; which the fornix projects to the hypothalamus; which the mammillothalamic tract projects to the thalamus (anterior nucleus); which projects back to the cingulate coex.
