We expand the differential diagnosis of LGI1-positive faciobrachial dystonic seizures (FBDS) by presenting a 67-year-old woman affected by seizures of similar semiology who was found to have insular epilepsy. We report the distinct characteristics of insular faciobrachial dystonic-like seizures that would help clinicians to differentiate them from typical LGI1-positive FBDS, thus, guiding thera...

The insula is a functionally and anatomically complex cortical structure that can be affected by both low-grade and high-grade gliomas. This complexity often prevents many neurosurgeons from attempting to surgically manage insular gliomas. This article reviews the anatomic and functional uniqueness of the insula and the surgical outcomes and lessons learned from previously reported surgical ser...

the purpose of this research was to investigate the effect of mir-429 ectopic over-expression on u251 glioblastoma cell line. it has been shown that mir-429 could target bmk1 and reduce glioma cells invasion. we cultured u251-mir-429 cells and observed changes in their morphology for 14 days. they seemed to become wider with expanded cytoplasm and go on differentiation. neuronal (nefm, nse and ...

The columnar organization is most apparent in the whisker barrel cortex but seems less apparent in the gustatory insular cortex. We addressed here whether there are any differences between the two cortices in columnar information processing by comparing the spatiotemporal patterns of excitation spread in the two cortices using voltage-sensitive dye imaging. In contrast to the well known excitat...

The insular cortex (IC) is widely believed to be an important forebrain structure involved in cognitive and sensory processes such as memory and pain. However, little work has been performed at the cellular level to investigate the synaptic basis of IC-related brain functions. To bridge the gap, the present study was designed to characterize the basic synaptic mechanisms for insular long-term p...

Although the primate insular cortex has been studied extensively, a comprehensive investigation of its neuronal morphology has yet to be completed. To that end, neurons from 20 human subjects (10 males and 10 females; N = 600) were selected from the secondary gyrus brevis, precentral gyrus, and postcentral gyrus of the left insula. The secondary gyrus brevis was generally more complex in terms ...

Glioma is one of the most common primary brain tumors, and mortality due to this disease second only cardiovascular cerebrovascular diseases. In traditional surgery, it difficult eradicate glioma; often recurrence increases its malignant degree, leading a large number patients killed by disease. It important subjects study pathogenesis explore effective treatment methods. Research on glioma mec...

BACKGROUND AND PURPOSE Stroke and neurodegeneration cause significant brain damage and cognitive impairment, especially if the insular cortex is compromised. This study explores for the first time whether these 2 causes differentially alter connectivity patterns in the insular cortex. METHODS Resting state-functional magnetic resonance imaging data were collected from patients with insular st...

The taxonomic status of the small bodied hominin, Homo floresiensis, remains controversial. One contentious aspect of the debate concerns the small brain size estimated for specimen LB1 (Liang Bua 1). Based on intraspecific mammalian allometric relationships between brain and body size, it has been argued that the brain of LB1 is too small for its body mass and is therefore likely to be patholo...
