2) Hoffman auditory hallucination score was negatively correlated with the DC of the bilateral putamen, but positively correlated with the DC of the left superior frontal gyrus in patient with AH group [Figure 2].
Compared with the healthy control subjects, the patients with PD showed increased fALFF values in the left inferior temporal gyrus (ITG), right IPL and right middle frontal gyrus (MFG) ( P < 0.
In the dorsolateral region of the left superior frontal gyrus, in one cluster, the investigators also found significantly in--creased connectivity (cluster size 673 voxels; P = .
And the right inferior frontal gyrus was more active for metaphors, New scientist reported.
Using surface based morphometry (SBM), Fan and Colleagues [6] found that individuals with OCD had greater cortex thickness in the right inferior parietal region and increased gyrification indices in the left insula, left middle frontal gyrus, left lateral occipital region extending to the precuneus, and in the right supramarginal gyrus.
The right inferior frontal gyrus, which plays an important role in attention when adaptation is required, activated in both the control children and those with bipolar disorder when they made an error in the task, but the children with severe mood dysregulation showed much less activation in this area, she said.
These brain regions included the temporal poles, the superior temporal sulcus, the superior frontal gyrus, the dorsomedial prefrontal cortex and the fusiform face area.
But children with dyslexia who at baseline showed greater activation in the right inferior frontal gyrus during a specific task and whose white matter connected to this right frontal region was better organized showed greater reading improvement over the next two-and-a-half years.
Their score on the Beck Depression Inventory also improved in correlation with decreased activation in the superior frontal gyrus and postcentral gyrus.
All cortical regions were smaller in the ADHD adults, but only the frontal lobe and medial paralimbic areas were significantly smaller, he said, and noted that the most substantial volumetric differences were observed in the ACC and the superior frontal gyrus.
Learning nouns activates the left fusiform gyrus, while learning verbs switches on other regions (the left inferior frontal gyrus and part of the left posterior medial temporal gyrus)", Antoni Rodriguez-Fornells, co-author of the study and an ICREA researcher at the Cognition and Brain Plasticity Unit of the University of Barcelona, tells SINC.
