Exploring the neurosurgical anatomy of the human insula: a combined and comparative anatomic-radiologic study.

Abstract

The human insula constitutes the invaginated portion of the cerebral cortex and is less well understood than other cortical areas because of its hidden location. Our purpose was to study the neurosurgical anatomy of the human insula via a combined and comparative study of its gross and imaging anatomy. We totally studied the anatomy of 148 normal insulae in anatomic specimens and radiologic images. We evaluated the number of all insular gyri (short and long), we statistically analyzed our results, and we made comparisons among hemispheres and gender. We also compared the two studies. Finally, we searched in the literature to make comparisons with other authors and to add our experience to the today existing knowledge of the insular anatomy. We found a significantly greater value of the insular gyri number for males, potential underestimation of the real insular gyri number by MRI and that the classic insular gyri pattern can rarely be absent. The middle short insular gyrus can be indistinguishable more likely on MRIs than during surgery, the long insular gyri are less curved than the short gyri, and finally, the insular perforating vessels usually originate at the inferior insular part. Deep knowledge of the gross, imaging, and...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
