The NIRS study with neurological patients [22] showed the occurrence of hemodynamic changes in the MI and ME of swallowing in patients with dysphagia and in a more pronounced form, in the inferior frontal gyrus, reinforcing the possibility to rehabilitate this function through the MI.

With regard to parkinsonisms, impaired emotion recognition in PSP patients have been associated with gray matter atrophy in the right inferior frontal gyrus [188], while in CBS neuroimaging analyses revealed that emotion-processing deficits were associated with the atrophy of the paracentral gyrus/precuneus region, as well as of the basal ganglia [163].
Two systems for empathy: a double dissociation between emotional and cognitive empathy in inferior frontal gyrus versus ventromedial prefrontal lesions.

Moreover, involuntary processing such as salience detection, interoception, and conflict monitoring and resolution, and involuntary attention is automatic and involves the brain areas, including the bilateral insula cortex, anterior cingulate cortex, ventromedial prefrontal and orbitofrontal cortex, inferior frontal gyrus, and inferior parietal lobule [25-28].
* Orbitofrontal Artery (OBFA): This branches out anterior, superior, and laterally to vascularise the inferior frontal gyrus. This "competes" in size with the frontal polar branch of the anterior cerebral artery.
In a surgical procedure which lasted two hours and a half, he resected 2.5 grams of cortex, excising both pars opercularis and pars triangularis of the inferior frontal gyrus of the left hemisphere.
Results: The main areas with increased brain activation were in frontal and parietal lobe, including left medial frontal gyrus, left inferior frontal gyrus, right middle frontal gyrus, right postcentral gyrus, and inferior parietal lobule in patients after CRT, yet no decreased brain activation was found.
NAJP: Where do the inferior frontal gyrus and the hippocampus come into the equation?
For happy and sad photo conditions, SPS was associated with activation of brain regions involved in awareness, integration of sensory information, empathy, and action planning (e.g., cingulate, insula, inferior frontal gyrus [IFG], middle temporal gyrus [MTG], and PMA).
