gyrus

 [ji´rus] (pl. gy´ri) (L.)
one of the many convolutions of the surface of the cerebral hemispheres caused by infolding of the cortex, separated by fissures or sulci; called also cerebral gyrus.
angular gyrus one continuous anteriorly with the supramarginal gyrus.
annectent gyri various small folds on the cerebral surface that are too inconstant to bear specific names; called also gyri transitivi.
Broca's gyrus inferior frontal gyrus.
central gyrus, anterior precentral gyrus.
central gyrus, posterior postcentral gyrus.
cerebral gyrus gyrus.
Cerebral gyri. From Applegate, 1996.
cingulate gyrus (gyrus cin´guli) an arch-shaped convolution situated just above the corpus callosum.
frontal gyrus any of the three (inferior, middle, and superior) gyri of the frontal lobe.
fusiform gyrus one on the inferior surface of the hemisphere between the inferior temporal and parahippocampal gyri, consisting of a lateral (lateral occipitotemporal gyrus) and a medial (medial occipitotemporal gyrus) part.
hippocampal gyrus (gyrus hippocam´pi) one on the inferior surface of each cerebral hemisphere, lying between the hippocampal and collateral fissures; called also parahippocampal gyrus.
infracalcarine gyrus (lingual gyrus) one on the occipital lobe that forms the inferior lip of the calcerine sulcus and, together with the cuneus, the visual cortex.
marginal gyrus the middle frontal gyrus.
occipital gyrus any of the three (superior, middle, and inferior) gyri of the occipital lobe.
occipitotemporal gyrus, lateral the lateral portion of the fusiform gyrus.
occipitotemporal gyrus, medial the medial portion of the fusiform gyrus.
orbital gyri irregular gyri on the orbital surface of the frontal lobe.
parahippocampal gyrus hippocampal gyrus.
paraterminal gyrus a thin sheet of gray matter in front of and ventral to the genu of the corpus callosum.
postcentral gyrus the convolution of the frontal lobe immediately behind the central sulcus; the primary sensory area of the cerebral cortex; called also posterior central gyrus.
precentral gyrus the convolution of the frontal lobe immediately in front of the central sulcus; the primary motor area of the cerebral cortex; called also anterior central gyrus.
gyrus rec´tus a cerebral convolution on the orbital aspect of the frontal lobe.
supramarginal gyrus that part of the inferior parietal convolution which curves around the upper end of the fissure of Sylvius.
temporal gyrus any of the gyri of the temporal lobe, including inferior, middle, superior, and transverse temporal gyri; the more prominent of the latter (anterior transverse temporal gyrus) represents the cortical center for hearing.
gy´ri transiti´vi annectent gyri.
uncinate gyrus the uncus.

cin·gu·late gy·rus

[TA]
a long, curved convolution of the medial surface of the cortical hemisphere, arched over the corpus callosum from which it is separated by the deep sulcus of corpus callosum; together with the parahippocampal gyrus, with which it is continuous behind the corpus callosum, it forms the fornicate gyrus.

Asymmetry indices in the posterior cingulate gyrus, superior parietal lobule, fusiform, precentral gyrus, and precuneus smoothly ranged around zero in both MCI converters and nonconverters, indicating very mild asymmetry from baseline to follow-ups.
The connections and related regions that were previously reported to have increased functional connectivity for PD patients are in the sensorimotor cortex, SMA, cingulate gyrus, primary motor cortex, and parietal cortex [13].
As shown in Table 2, the MMSE scores correlated positively with the NAA/Cr ratio in the left posterior cingulate gyrus (r = 0.56; p = 0.001).
If the amygdala has Lewy bodies, additional [alpha]-synuclein immunostaining should be performed on anterior cingulate gyrus, and if Lewy bodies are seen in the cingulate, then additional [alpha]-synuclein immunostaining should be performed on frontal, temporal, and parietal neocortex for grading of the Lewy body pathology.
Matthew Apps and Narender Ramnani, from Royal Holloway, University of London, said: "The great complexity of human social interactions and the huge variation in what we find rewarding compared with other primates prompts questions about whether the anterior cingulate gyrus operates similarly in the human brain."
After neurofeedback, the activity in her cingulate gyrus reduced to 1.3 standard deviations, well within the typical range, and the hair on her head grew in for the first time since early childhood.
Another important structure of this medial default network is the cingulate gyrus. This cingulate cortex appears to have a central role in integrating a person's emotional brain with the parts of the brain that store knowledge.

In looking at both the gray matter and white matter of the brain, researchers found that the people defined as obese had lost brain tissue in the frontal and temporal lobes, areas of the brain critical for planning and memory, as well as in the anterior cingulate gyrus (attention and executive functions), hippocampus (long-term memory), and basal ganglia (movement).
In addition, whenever there is hypogenesis or agenesis, there is failure of inversion of the cingulate gyrus.
Comparison of the SPECT scans revealed that four areas became hyperactive during the cataplectic attack: the cingulate gyrus (an enfolding of brain tissue located deep within the cerebral fissure); the left and right orbitofrontal cortices; the right temporal cortex; and the right putamen (a basal ganglia structure).
