What are the various libmic pathways that are being recognized subserving the functions of the limbic system at present?

Components of the cyclic limbic path. A cyclic path may underlie the functioning of the limbic system. The links in this cyclic path on the medial aspects of the cerebral hemispheres and on either side of the brain starting with the mamillary body include the following. 1. The mamillothalamic tract from the mamillary body of the posterior hypothalamus to the anterior nuclear group of the dorsal thalamus. 2. Thalamocortical radiations from the anterior nucleus of the dorsal thalamus to the cortex of the cingulate gyrus. 3. The cingulum bundle (a fiber bundle in the cingulate gyrus) over which discharge is made to the parahippocampal gyrus. 4. Short association fibers over which relay is made from the parahippocampal gyrus to the hippocampus and the amygdaloid body. 5. The fimbria–fornix system from the hippocampus to the septal area and back to the mamillary body of the posterior hypothalamus. 6. The stria terminalis interrelating the amygdala and the hypothalamus. 7. All the major regions of synapse in this cyclic path are under the influence of, and influence the activities of the limbic association cortex which includes the anterior temporal lobe, insula, orbital and medial prefrontal, parahippocampal, and cingulate cortices. Another important fiber bundle of the amygdaloid body is the ventral amygdalofugal path (VAFP) that travels beneath the globus pallidus to enter the hypothalamus.
