Brain imaging studies may lead to such a treatment by helping scientists understand the exact roles of hypocretinergic pathways, as well as the hypothalamus, amygdala, inferior frontal gyrus
and other brain structures in cataplexy.
Researchers have also demonstrated a lower correlation of activation in dyslexics between left angular gyms, fusiform gyms, and inferior frontal gyrus
(Horwitz, Rumsey, & Donohue, 1998).
The inferior margin borders on the Sylvian fissure (lateral fissure) separating it from the temporal lobes.[18,23] The prefrontal region lies anterior to the motor area, located just anterior to the central fissure, while Broca's area is situated at the inferior frontal gyrus
Furthermore, lateralized cortical decreases were observed in the right middle frontal gyrus, inferior frontal gyrus
, precentral gyrus, superior temporal gyrus, thalamus, and putamen and in the left cuneus, precuneus, cingulate gyrus, fusiform gyrus, middle temporal gyrus, and medial frontal gyrus.
As for ReHo, increased ReHo was observed in the left cerebellum anterior lobe (CAL) and right calcarine, while it was decreased in the left dorsolateral superior frontal gyrus (SFG), the left precuneus/posterior cingulate cortex (PCu/PCC), the left triangular part of inferior frontal gyrus
, the and middle frontal gyrus (IFGtri/MFG).
As shown in Figure 1 and Table 2, the ReHo values were higher in depressed patients in the right superior temporal gyrus, right middle temporal gyrus, left inferior temporal gyrus, left middle temporal gyrus, right middle frontal gyrus, triangular part of the right inferior frontal gyrus
, orbital part of the right inferior frontal gyrus
, right superior occipital gyrus, right middle occipital gyrus, bilateral anterior cingulate, and paracingulate gyri, and values were reduced in the right fusiform gyrus, left middle occipital gyrus, left lingual gyrus, and left inferior parietal except for the supramarginal and angular gyri.
In addition to the left BA47 (Inferior frontal gyrus
--Pars orbitalis) that has the highest intensity, the following regions appear "activated": BA46, BA6, BA 13, BA37, BA20, BA21, BA22, BA7 and BA18
Trained participants showed transfer to an untrained inhibition task and brain structural plasticity in right inferior frontal gyrus
, a brain region associated with inhibition of prepotent actions.
White matter tract abnormalities between rostral middle frontal gyrus, inferior frontal gyrus
and striatum in first-episode schizophrenia.
Furthermore, T1D patients showed greater activations in the right inferior frontal gyrus
, cerebellum, basal ganglia, and substantia nigra.
The left inferior frontal gyrus
had reduced brain activation during easier tasks, while the middle frontal gyrus and the superior frontal gyrus were affected during more difficult tasks (Diabetes Care 2014 Nov.
Compared with the resting-state, acupuncture at the real acupoints activated brain regions primarily in the left calcarine gyrus, bilateral middle occipital gyrus (BA19), bilateral middle temporal gyrus (left BA 22), left inferior temporal gyrus, left inferior frontal gyrus
, left superior medial prefrontal gyrus (left BA 10), right anterior cingulate cortex (right BA 10), left postcentral gyrus, left caudate nucleus, and the bilateral cerebellum (Crus 2 and VIII).
