Compared with the normal elderlies, ReHo values decreased in aMCI patients in the left temporal lobe (middle temporal gyrus and inferior temporal gyrus), left parahippocampal gyrus, occipital lobe, lingual gyrus, precuneus, and other regions (P<0.05; Figure 3, Table 1), while ReHo values increased in the right side frontal lobe (inferior frontal gyrus), left superior temporal gyrus, precentral gyrus (frontal lobe), right thalamus, the left fusiform gyrus, and other regions (P<0.05; Figure 4, Table 2).
The results indicated that using the activation signals from the attention-function-related region (middle frontal gyrus-angular gyrus)(7) and the motor-function-related region (precentral gyrus)(8) were optimal for correctly distinguishing the presence or absence of concurrent ASD.
Results: In the longitudinal comparisons, the brain structure (GM volume of the right precentral gyri, left postcentral gyri, and right thalami) and perfusion (CBF of the bilateral temporal poles, left precentral gyri, postcentral gyri, and right middle temporal gyri) in both motor and extramotor areas at follow-up were impaired to different extents when compared with those at baseline (all P < 0.05, false discovery rate adjusted).
La deficiencia de hierro cerebral en el sindrome de piernas inquietas es capaz de producir un deficit significativo de mielina, confirmado por estudios de imagen que demuestran una disminucion significativa de la sustancia blanca en el cuerpo calloso, el cingulo anterior y el giro precentral. La disminucion de la mielinizacion contribuye a los sintomas de la enfermedad en relacion con la integracion sensorimotora que tiene una senalizacion tiempo dependiente (58).
(55) Based on examination of rodent cellular structure, lamination, and projection patterns, findings suggest there are clear distinctions between the dorsal (precentral and anterior cingulate) and ventral (prelimbic, infralimbic, and medial orbital) subdivisions of the mPFC.
When age was taken into account, age-related volume deficits were seen in the control group in five of the six cortical regions, but the alcoholism group showed a significantly greater deficit in the precentral and superior frontal cortex.
[13] Furthermore, the research team found that there were regional connectivity abnormalities in the bilateral superior medial prefrontal lobe, left superior temporal gyrus(STG), left paracentral lobule, right precentral lobule, and right inferior parietal lobe of the AOS patients by utilizing the regional homogeneity (ReHo) analysis, proposing to use the combination of ReHo values in the medial prefrontal lobe, left superior temporal gyrus, and right inferior parietal lobe as biomarkers (sensitivity of 88.24%, specificity of 91.89% and accuracy of 90.14%) for AOS patients.
This delay was found to be statistically higher adjacent to the frontal gyrus (adjacent to the inferior frontal gyrus, p<0.05) and at the vertex of the brain (precentral sulcus, p<0.01).
En contraposicion a ello, los no AAV mostraban mayor afectacion en el giro temporal superior y la circunvolucion precentral. En cuanto a la conectividad interhemisferica, la medida obtenida de las DMN correlacionaba con las puntuaciones en las escalas de valoracion de sintomas.
