Resection of tumoral lesions anatomically related to motor, sensitive and language areas of the brain, have the main goal of sparing those areas. For that purpose, Neurosurgery on awake patients helps in reducing the size of growing brain tumors in a safe manner, which leads to extending and improving qu...
Abstract Introduction The analysis of the electrical activity of the brain using scalp electrodes with electroencephalography (EEG) could reveal the depth of anesthesia of a patient during surgery. However, conventional EEG equipment, due to its price and size, are not a practical option for the operati...

Background: The crossed cerebro-cerebellar (CCC) activation facilitates the diagnosis of cortical language lateralization, but needs to be explored with language tasks suitable for patients with different age ranges, educational attainment and eventual presence of language deficits. Aim: To determine the...
In 1909, Korbinian Brodmann described 52 functional brain areas, 43 of them found in
the human brain. More than a century later, his devoted functional map was
incremented by Glasser et al in 2016, using functional nuclear magnetic resonance
imaging techniques to propose the existence of 180 functional a...
Introducción: El lóbulo de la ínsula, o ínsula, se encuentra oculto en la superficie lateral del cerebro. La ínsula está localizada profundamente en el surco lateral o cisura silviana, recubierta por los opérculos frontal, parietal y temporal.
Objetivo: Estudiar la compleja anatomía del lóbulo d...
ABSTRACT Drug-resistant epilepsy associated with central nervous system tumors is generally caused by low grade gliomas. This group of tumors is usually found in brain eloquent areas, such as the insular lobe, rolandic cortex and supplementary motor area and, historically, possess a greater risk of posto...

OBJECTIVES: Approximately one-third of candidates for epilepsy surgery have no visible abnormalities on conventional magnetic resonance imaging. This is extremely discouraging, as these patients have a less favorable prognosis. We aimed to evaluate the utility of quantitative magnetic resonance imaging i...
This study aimed to explore the structural and functional characteristics of the neural network of resting-state brain activities in patients with amnestic mild cognitive impairment (aMCI) by functional magnetic resonance imaging (fMRI) technology. Resting state fMRI scanning was performed on 10 clinical...
