Post-hoc analysis showed that NC with HL had lower fALFF in bilateral ITG compared to NC with NHL. A whole-brain analysis indicated that activation in middle/inferior temporal gyrus and temporal fusiform cortex in the contrast of Meaningless > Baseline was . The preoccipital notch is an indentation in the inferior temporal gyrus, about 3 cm anterior to the occipital pole, formed by the petrous part of the temporal bone. At the gyral level of the frontal lobe, the maximal CSD was most frequent in the superior frontal gyrus (57 discharges, 31.5%), followed by the middle frontal gyrus (19 discharges, 10.5%), inferior frontal gyrus (13 discharges, 7.2%), and medial frontal gyrus (11 discharges, 6.1%). It is crucial for visual object recognition and is considered to be the final stage in the ventral cortical visual system. Broca's area. Typically, MRI shows symmetric T2/FLAIR hyperintensity in the mammillary bodies, hypothalami, medial thalami, tectal plate and periaqueductal area, but the cerebral cortex may also be involved Related to inherited myelin disorders Diffuse hyperintensity (arrows) is also noted in the cerebral white matter bilaterally age 2 years (28 months) White matter hyperintensities (WMH) of presumed . It extends into the superior temporal gyrus below the lateral sulcus, and is here surrounded by the auditory . The bone flap has been removed and the dura . In the left hemisphere additional activation were located in inferior temporal gyrus, the inferior part of pre- and postcentral gyrus, and orbitofrontal cortex (BA 11), whereas in the right hemisphere only a region in the precuneus (BA 19) was activated additionally. Functional disconnection is bilateral and extensive, peaking in the temporooccipital part of the left inferior temporal gyrus and the right inferior frontal gyrus pars triangularis. OBJECTIVE: The middle temporal gyrus and inferior temporal gyrus subserve language and semantic memory processing, visual perception, and multimodal sensory integration.Functional deficits in these cognitive processes have been well documented in patients with schizophrenia. The middle and inferior temporal gyri, by contrast, have received far less attention. 77: 587-598, 1997. Paul Broca had a patient called Leborgne who could only pronounce the word "tan" when speaking. Gyrus rectus/orbital gyri - Found on the inferior surface of the frontal lobe. It can also be divided into anterior fusiform gyrus and posterior fusiform gyrus. It is located primarily in the caudal portions of the fusiform gyrus and inferior temporal gyrus on the mediobasal and lateral surfaces at the caudal extreme of the temporal lobe. The temporal lobe is the second largest lobe, after the larger frontal lobe, accounting 22% of the total neocortical volume . The gyrus rectus, or straight gyrus, is located at the medial most margin of the inferior surface of frontal lobe 1, 2. 3) False about Broca's aphasia - a. Comprehension is preserved b. Areas 28, 34, 35, and 36: Parahippocampal gyrus, extending lateral and posterior from hippocampus. However, its timing can vary widely, hemisphere, specifically the superior and inferior frontal gyri, the so it is often described as the late positive complex (LPC), a precuneus, the angular gyrus, the parahippocampal gyrus, and definition which also includes later deflections, such as P500 and the hippocampus. The inferior temporal gyrus is one of three gyri of the temporal lobe and is located below the middle temporal gyrus, connected behind with the inferior occipital gyrus; it also extends around the infero-lateral border on to the inferior surface of the temporal lobe, where it is limited by the inferior sulcus.This region is one of the higher levels of the ventral stream of visual processing . The inferior temporal gyrus is bounded above by the inferior temporal sulcus and below by the lateral occipitotemporal sulcus (which sits on the inferior surface of the temporal lobe). A total of 15 consecutive cases were identified at our insti-tution with the presence of a subcortical cystic lesion within the anterior superior temporal gyrus, with imaging performed be- The basis for this discovery was the analysis of speech problems resulting from injuries to this region of the brain, located in the inferior frontal gyrus. Temporal lobe. Specifically, the left inferior-middle posterior temporal lobe (Brodmann's area 37), is located between the visual cortex and the anterior temporal cortex and becomes activated during a variety of language tasks, including reading and object and letter naming (Price, 2011). CASE SERIES CaseSelection We obtained institutional research ethics board approval for this study. Broca's aphasia often occurs as a result of strokes, most commonly affecting the ## middle cerebral artery territory.

The angular gyrus is a region of the brain lying mainly in the posteroinferior region of the parietal lobe, occupying the posterior part of the inferior parietal lobule. The radius of each ROI was 10 mm. These gyri, located on the lateral surface of the temporal neocortex, are involved in cognitive functions such as language, visual perception, and memory ( 2 - 4 ). We selected three regions located in the temporal lobe: anterior hippocampus, rhinal cortex, and middle temporal gyrus. The superior temporal gyrus is located between the sylvicus and the upper temporal sulcus, the middle - between the upper and lower temporal sulcus, the lower - between the lower temporal sulcus and the transverse cerebral fissure ().. Blood supply. It has been connected with processes as different as contemplating distance, recognition of known faces, audio-visual emotional recognition, and accessing word meaning while reading. Where is the lateral occipital gyri and what does it do? It is traditionally thought to reside in Brodmann area 22, which is located in the superior temporal gyrus in the dominant cerebral hemisphere, which is the left hemisphere in about 95% of right-handed individuals and 70% of left-handed individuals. Morphological landmarks of the ventral attention network are the inferior frontal gyrus, the frontal pole, the inferior parietal lobe (PFcm), the temporo-occipital part of the middle temporal gyrus, the anterior and posterior division of the cingulate gyrus, and the insular cortex. The gyrus extending from the inferior surface of the temporal lobe to the occipital lobe, also known as fusiform gyrus. Record- ing sites were also located in the lower bank of the superior temporal sulcus adjacent to the stippled area. At the gyral level of the frontal lobe, the maximal CSD was most frequent in the superior frontal gyrus (57 discharges, 31.5%), followed by the middle frontal gyrus (19 discharges, 10.5%), inferior frontal gyrus (13 discharges, 7.2%), and medial frontal gyrus (11 discharges, 6.1%). Anterior paracentral lobule - Found on the medial surface of the frontal lobe and is a continuation of the precentral gyrus. Its function is unclear but it may be involved in higher cognitive function (e.g. . The nodes were primarily located in the orbital frontal cortex, the sensory-motor cortex, the inferior frontal gyrus, the temporal lobe, the cingulate cortex, the posterior parietal lobe, the insular cortex, the occipital lobe and the subcortical nuclei. It forms part of Brodmann area 37, along with the inferior and middle temporal gyri . Damage caused to Wernicke's area results in receptive, fluent aphasia. The fusiform gyrus is a large region in the inferior temporal cortex that plays important roles in object and face recognition, and recognition of facial expressions is located in the fusiform face area (FFA), which is activated in imaging studies when parts of faces or pictures of facial expressions are presented to . Brodmann area 13 is located in the posterior part of the Orbitofrontal cortex, and can be subdivided into areas 13a, 13b, 13m, 13l. Previous functional neuroimaging studies have suggested that the middle temporal gyrus and inferior temporal gyrus are involved in several cogni- The inferior temporal gyrus in the monkey appears to be unique among the many extrastriate visual cortices in its importance for normal performance of delayed match-to-sample, a visual memory task. It is also involved in a number of processes related to .

Its significance is in transferring visual information to Wernicke's area, in order to make meaning out of visually perceived words. The female migraineurs also showed increased nodal centralities in the PFC (left BA9 . A straight line drawn from the parietooccipital sulcus to the preoccipital notch defines the anterior border of the occipital lobe on the lateral aspect of the hemisphere. The middle temporal gyrus and inferior temporal gyrus are involved in a number of cognitive processes, including semantic memory processing, language processes (middle temporal gyrus), visual perception (inferior temporal gyrus), and integrating information from different senses. The inferior temporal gyrus is placed below the middle temporal sulcus, and is connected behind with the inferior occipital gyrus; it also extends around the infero-lateral border on to the inferior surface of the temporal lobe, where it is limited by the inferior sulcus.This region is one of the higher levels of the ventral stream of visual processing, associated with the representation of .

Area 28 (ventral entorhinal) and area 34 (dorsal entorhinal): Adjacent to hippocampal subiculum. Inferior Temporal Gyrus is located where and does what? In the left cerebral hemisphere, it is one portion of Wernicke's area. 2c) and from this point follows a horizontal course before ending low in the inferior frontal pole. The cerebellum (unlabeled) is not part of the telencephalon. This area is the most widely studied visual area of the brain and is highly specialized for the processing of static and moving objects, as well as being good at recognizing patterns. The lobes of the cerebral cortex include the frontal (blue), temporal (green), occipital (red), and parietal (yellow) lobes. What is Brodmann's Area 37? The inferior temporal gyrus is one of three gyri of the temporal lobe and is located below the middle temporal gyrus, connected behind with the inferior occipital gyrus; it also extends around the infero-lateral border on to the inferior surface of the temporal lobe, where it is limited by the inferior sulcus.This region is one of the higher levels of the ventral stream of visual processing .

The inferior temporal gyrus (aka inferotemporal cortex) is placed below the middle temporal sulcus, and is connected behind with the inferior occipital gyrus; it also extends around the infero-lateral border on to the inferior surface of the temporal lobe, where it is limited by the inferior sulcus. The middle temporal gyrus is located between the superior temporal gyrus and inferior temporal gyrus . Broca's Area was first suggested to play a role in speech function by the French neurologist and anthropologist Paul Broca in 1861. Its anterior and posterior limits are defined similar to the middle temporal gyrus 1.. Location of recording sites. Increased CBF was seen in WM located in the pons, right temporal lobe, bilateral frontal lobe, bilateral partial lobe, and bilateral limbic lobe, and decreased CBF was seen in the corpus callosum in NPSLE patients. The inferior frontal sulcus merges with the precentral gyrus posteriorly on parasagittal slices ( Fig. The auditory cortex is the part of the temporal lobe that processes auditory information in humans and many other vertebrates.It is a part of the auditory system, performing basic and higher functions in hearing, such as possible relations to language switching.
