falciform_crescent - created
The falciform crescent (or crista falciformis) is a horizontal ridge that divides the internal acoustic meatus into superior and inferior portions. Superior The facial nerve and superior vestibular nerve (SVN) travel in the superior portion of the IAM with the facial nerve anterior to the SVN and separated from it in the lateral portion by […]

fundus
Fundus Lateral end of the internal auditory meatus, the wall of which is formed by the thin cribriform plate of bone separating the cochlea and vestibule from the internal acoustic meatus; a transverse crest divides the fundus into two regions; in the superior region are located the facial nerve area and the superior vestibular area; […]
fundal_fluid
The focus of vestibular schwannoma surgery has shifted from low mortality and tumor resection to retention of neurological function. Hearing preservation is another point in addition to facial nerve function preservation. Hearing preservation rates overall ranged from 2% to 93% in recent studies. Characteristics such as approach, pre-operative neurological function, tumor size, nerve of origin […]

sindrome_piramidal
Síndrome Piramidal - AFECTACIÓN DEL MOVIMIENTO VOLUNTARIO, pudiendo producirse una debilidad total o plejia, una debilidad parcial o paresia o una torpeza de movimientos finos del hemicuerpo ipsilateral a la lesión medular si ésta es hemimedular, de las cuatro extremidades en lesiones completas superiores al nivel C5 o de la extremidades inferiores en lesiones inferiores […]
sindrome_de_cono_medular_espinal
Síndrome de cono medular - Forma de inicio del cuadro clínico: frecuentemente súbita. - Síntomas y signos bilaterales y simétricos, afectando a: • Sistema motor: con signos piramidales leves. • Reflejos miotáticos presentes (salvo en lesiones del epicono en que los reflejos aquíleos están ausentes)
cono_medular
Cono medular El final de la médula se denomina cono medular y termina a nivel del disco intervertebral entre la 1 y la 2da vértebra lumbar. Del cono medular emerge el filum terminale. Esta formado en su mayor parte de piamadre. Los ependimomas constituyen el 90 % de los tumores que se originan del filium […]
sindrome_centromedular
Síndrome centromedular Es el más común de las lesiones medulares incompletas , ocurre en los niveles cervicales y se caracteriza por mayor debilidad en los miembros superiores que en los inferiores y preservación al menos parcial sacra. Habitualmente se produce en pacientes ancianos con cambios degenerativos en la columna cervical tras una hiperextensión de la […]

Gene Identified That May Provide Potential Therapy for Cerebral Cavernous Malformations 20 October, 2017
Researchers at University of California San Diego School of Medicine, with national collaborators, have identified a series of molecular clues to understanding the formation of cerebral cavernous malformations (CCMs). The study offers the first genome-wide analysis of the transcriptome of brain microvascular endothelial cells after KRIT1 inactivation. “These mouse studies reveal a critical mechanism in the pathogenesis […]
Alzheimer’s Gene Poses Both Risk — and Benefits 20 October, 2017
Study suggests role of inflammation in brain disease is complicated Scientists drilling down to the molecular roots of Alzheimer’s disease have encountered a good news/bad news scenario. A major player is a gene called TREM2, mutations of which can substantially raise a person’s risk of the disease. The bad news is that in the early stages […]
Regenerative Medicine Restores Movement After Paralysis 19 October, 2017
Twelve-month data from spinal cord injury trial shows two-thirds of subjects recovered two or more motor levels Four of six people with paralyzing spinal cord injuries who were treated with a new cell therapy have recovered two or more motor levels on at least one side, new study results show. This 67 percent recovery rate […]
First Whole-Brain Map of Inhibitory Neurons Reveals Surprises 19 October, 2017
Researchers at Penn State College of Medicine and Cold Spring Harbor Laboratory have reported the first-ever quantitative whole-brain map of inhibitory neurons in the mouse brain. These brain cells play a crucial role in regulating response to stimuli and have been widely implicated in many psychiatric conditions. The researchers found surprising differences in the number of inhibitory neurons in […]
For Women, High Blood Pressure in Your 40s May Be Tied to Increased Risk of Dementia 18 October, 2017
Women who develop high blood pressure in their 40s may be more likely to develop dementia years later, according to a study. “High blood pressure in midlife is a known risk factor for dementia, but these results may help us better understand when this association starts, how changes in blood pressure affect the risk of […]
Study Reveals Staggering Economic Burden of Dementia in Younger People 18 October, 2017
First-of-its-kind Study on Frontotemporal Degeneration Led by FAU You may not have heard of it, but frontotemporal degeneration (FTD) accounts for 20 to 50 percent of dementia cases in people under the age of 65. FTD ravages an individual’s quality of life by dramatically altering their language, personality, behavior, cognition and motor function. But […]
‘Khamisiyah Plume’ Linked to Brain and Memory Effects in Gulf War Vets 17 October, 2017
In previous research, Linda Chao, PhD, and colleagues of San Francisco VA Medical Center reported decreased volume of the hippocampus—a brain area involved in memory processing—in Gulf War veterans exposed to the Khamisiyah plume. In that 1991 event, demolition of an Iraqi munitions depot caused US soldiers to be exposed to low levels of nerve […]
Transcranial Direct Current Stimulation Shown to Reduce Fatigue Associated with Multiple Sclerosis 17 October, 2017
New randomized trial may point to potential treatment option People with multiple sclerosis (MS) who underwent a non-invasive form of electrical brain stimulation experienced significant reductions in fatigue, a common and often debilitating symptom of the disease, according to new research from the Multiple Sclerosis Comprehensive Care Center at NYU Langone Health. When compared to patients […]
Concussion: How the NFL came to shape the issue that plagued it 16 October, 2017
Players kneeling during the national anthem is the most recent NFL controversy, but certainly not the first nor the biggest. Concussion has dogged the NFL since the 1990s, and its initial response––avoidance and superficial gestures to mollify critics––damaged its public image. However, in recent years, the league has repositioned itself as a leader in concussion […]
Transcranial Electrical Stimulation Shows Promise for Treating Mild Traumatic Brain Injury 16 October, 2017
Using a form of low-impulse electrical stimulation to the brain, documented by neuroimaging, researchers at the University of California San Diego School of Medicine, Veterans Affairs San Diego Healthcare System (VASDHS) and collaborators elsewhere, report significantly improved neural function in participants with mild traumatic brain injury (TBI). TBI is a leading cause of sustained physical, […]
