With adequate Sylvian fissure dissection, it is effective to widely expose the insular cortex without damage to the frontal or temporal cortex.
Thalamus, frontal cortex white matter (61), anterior cingulate (ACC), insular cortex and grey matter (62) did not show differences in Cre levels in this population compared to HC.
Suntildeer said, "Many ongoing studies looking at the link between different areas of the brain and addiction are discovering that the insular cortex plays a very important role.
Caselli cautioned that subgroup analyses "get tricky and risk bias," and wondered "why should the insular cortex specifically show such a strong effect?
Oral administration of EGb 761 (Exp 1) increased Fos-IR moderately, but significantly, in the insular cortex ([t.
Though wholly consistent structural-functional correlations are difficult to discern from the studies just reviewed, they generally confirm that dorsal and perigenual ACC, neocortical regions proximal to ACC, and insular cortex are the primary cortical regions contributing to autonomic regulation of the cardiovascular system in humans.
8) Cytotoxic edema of gray matter is seen as increased T2 signal and, in the case of MCA ischemia, is often first identified in the region of the insular cortex (ie, the MR corollary of the "insular ribbon" sign on a CT scan) or involving the lentiform nuclei of the basal ganglia (ie, the MR corollary of "obscuration" of the lentiform nucleus on a CT scan).
But the new study surprised scientists by revealing disgust originates in quite a different area, the anterior insular cortex, part of the brain's outer layer, known as "grey matter", which deals with higher functions.
Seizures arising from the temporal lobe may invade the insular region in the majority of the patients, but in approximately 10% of cases, the seizures may be originated in the insular cortex itself (3,4).
Fifteen months after onset, a 24-h electroencephalography (EEG) was unremarkable, and brain MRI showed atrophy in the right insular cortex, caudate, putamen, and cerebral crus with high signals in the corona radiata on T2-weighted and fluid-attenuated inversion recovery images.
In addicts, the insular cortex is activated when they are exposed to environmental cues that trigger craving because the insulae are a target for the dopamine system.
Specifically, males on average had larger volumes and higher tissue densities in the left amygdala, hippocampus, insular cortex, putamen; higher densities in the right VI lobe of the cerebellum and in the left claustrum; and larger volumes in the bilateral anterior parahippocampal gyri, posterior cingulate gyri, precuneus, temporal poles, and cerebellum, areas in the left posterior and anterior cingulate gyri, and in the right amygdala, hippocampus, and putamen.
