<prompt> In the Papez circuit of the limbic system, between which combination is the hypothalamus placed on the basis of function?Cingulate coex-hippocampusHipocampus-thalamusThalamus-hippocampusThalamus-cingulate coex  <response>: 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.
