The posterior cingulate gyrus is richly interconnected with the superior parietal lobe (area 7) the parahippocampal (inferior) temporal and superior temporal lobe (area 22), frontal lobe, caudate, putamen, substantia nigra, pulvinar of the thalamus, and dorsal hypothalamus (Beleydier and Mauguiere 1980; recently reviewed in Devinksy et al.
However, the posterior cingulate may also be involved in visual-spatial and memory-cognitive activities, particularly as relates to the body and movement -hence the interconnections with the superior parietal lobe and the parahippocampal gyrus.
The myelination of the corticospinal tract coincides with the descent of the larynx, the myelinization and development of the amygdala and the amygdalafugal brainstem pathway, and later, the maturation of the cingulate gyrus and its pyramidal brainstem pathways (Debakan, 1970; Langworthy, 1937; Yakovlev and Lecours, 1967; Yakovlev, and Rakic, 1966).

The cingulate gyrus is an arched convolution that lies next to the corpus callosum and is separated from it by the sulcus of the corpus callosum.
It begins below the rostrum, curves around in front of the genu, extends along the trunk, and then turns downward behind the splenium of the corpus callosum, where it is connected by the narrow "isthmus of the cingulate gyrus" to the parahippocampal gyrus.
It is separated from the "medial frontal gyrus" by the cingulate sulcus and from the "precuneus" by the more variable "suprasplenia sulcus." It has many connections with the anterior thalamic nuclei and is often considered to be part of the "limbic system."

Its approximate boundary on the medial aspect of the hemisphere is the cingulate sulcus and, on the lateral aspect, the inferior frontal sulcus.
Approximate boundaries are the cingulate sulcus dorsally and the parieto-occipital sulcus caudally.
Occupies the postcentral gyrus and the precentral gyrus between the ventrolateral extreme of the central sulcus and the depth of the lateral sulcus at the insula.

 Efferent connections of the cingulate gyrus in the rhesus monkey.   (Site not responding. Last check: )
Efferent cortical connections of the cingulate gyrus are investigated in rhesus monkey using autoradiographic technique.
The results indicate that the rostralmost part of the cingulate gyrus (area 32) sends projections to the lateral prefrontal and midorbitofrontal cortex and to the rostral portion of the superior temporal gyrus.
It seems that the connections of the rostralmost part of the cingulate gyrus resemble the efferent cortical connectional patterns described for lateral prefrontal and orbito-frontal cortex, whereas the projections of areas 24 and 23 are directed to the neocortical, the paralimbic and the limbic areas.

The anterior cingulate gyrus, in the frontal cerebral cortex, is an essential neural system for the expression of the primate isolation call, a structural and functional equivalent of the cry sounds of humans.
Humans suffering infarct damage to this region likewise show an initial recovery in the form of short, faint, monosyllabic sounds, suggesting that the anterior cingulate gyrus of nonhuman primates is the evolutionary precursor of a neural structure involved in human affective expression and speech.
Since the anterior cingulate region also has reciprocal connections with temporal lobe auditory cortex, a presumptive feedback pathway exists for registering commands to initiate vocalization with the temporal lobe cortex, which plays a major role in perceiving and decoding the acoustic details of species-specific vocalizations.

Additionally, the rostral anterior cingulate gyrus an area related to logical thought was 6 percent smaller in the high-symptom group than in the low-symptom group.
More surprisingly, however, strong responses were also found within the cingulate gyrus, an area not previously associated with face processing.These selective brain regions also seemed to be sensitive to the cues of identity, suggesting that they may also be involved in recognising individuals."Adults show large variations in how good they are at recognizing faces,...
