The Role of Intraoperative Neurophysiological Monitoring in Intracranial Cavernous Malformation Surgery: A Narrative Review [PDF]

Iranian Journal of Medical Sciences
Cavernous malformations, also known as cavernous hemangiomas or cavernomas, are abnormal vascular lesions that can occur in various parts of the body, including intracranially.

Motor Evoked Potentials Improve Targeting in Deep Brain Stimulation Surgery

Neuromodulation: Technology at the Neural Interface, EarlyView., 2021
Abstract Objectives One of the main challenges posed by the surgical deep brain stimulation (DBS) procedure is the successful targeting of the structures of interest and avoidance of side effects, especially in asleep surgery. Here, intraoperative motor evoked potentials (MEPs) might serve as tool to identify the pyramidal tract.

Lpd depletion reveals that SRF specifies radial versus tangential migration of pyramidal neurons [PDF]

, 2010
During corticogenesis, pyramidal neurons (~80% of cortical neurons) arise from the ventricular zone, pass through a multipolar stage to become bipolar and attach to radial glia[superscript 1, 2], and then migrate to their proper position within the ...

T-value significance maps superimposed on the main white matter tracts.

, 2015
T-value significance maps of the association between homocysteine and mean diffusivity (MD) (a-d) and axial diffusivity (AD) (e-h) were superimposed on the four major white matter tracts that were involved: the pyramidal tracts (a,e), ponto-cerebellar ...

The pyramidal syndrome and the pyramidal tract: a brief historical note [PDF]

Arquivos de Neuro-Psiquiatria, 2011
The discovery of the pyramidal syndrome and tract is briefly reviewed with emphasis on a few key historical aspects. The pursuit of the relationship between the lateralized deficits resulting from contralateral head trauma begins in the fourth century BC with the Hippocratic School and continues until the present day.

A Depolarizing Leak in Sodium Bicarbonate Cotransporter NBCe1 Causes Brain Edema

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives SLC4A4 encodes electrogenic sodium bicarbonate cotransporter NBCe1, prominently expressed in kidney and brain. Recessive loss‐of‐function variants in SLC4A4 cause proximal renal tubular acidosis, no brain edema. In the brain, NBCe1 is expressed by astrocytes, where it regulates pH and mediates astrocyte volume changes.

Ultrastructural investigation on bovine Brunner's glands

Translational Research in Anatomy, 2019
Brunner’s glands are branched tubulo-acinar glands principally located within the lamina propria and the submucosa of the small intestine of mammals. Previous histochemical studies of Brunner’s glands in cattle have shown that the glandular lobules can ...

SPG4 and Dementia: Expanding the Clinical Spectrum

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Hereditary spastic paraplegia (HSP) is a group of disorders characterized by progressive spasticity and lower limb weakness, with mutations in SPG4/SPAST being the most common cause. Detailed studies and clinical and molecular comparisons across different populations are missing.
