An integrated multipurpose lesion-making electrode

Neurosurgery

Abstract

Although excellent results are reported from centers using microelectrode mapping during stereotactic pallidotomy, the recording methods used are time-consuming and technically cumbersome. We sought to develop a new electrode concept that may, when eventually applied in clinical practice, improve the efficiency and safety of microelectrode-guided functional neurosurgical procedures. The scout electrode uses a recently developed research technique for simultaneously obtaining multiple microelectrode recordings along the shaft of a macroelectrode. By positioning recording sites on either side of a lesion-making contact, it is possible to functionally "scout" the brain tissue surrounding the proposed lesion site, thus eliminating the need for serial movements and electrode interchanges. The feasibility of the scout electrode concept was tested using prototypes placed into cat medial geniculate nucleus. High-quality unit recordings were simultaneously obtained from different regions within the medial geniculate nucleus. This ability to physiologically map sites above and below the lesion-making contact facilitated precise placement of radiofrequency lesions in the center of the medial geniculate nucleus. These results suggest that ...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.
