The Department of Defense (DoD) is extremely interested in the neurological care of their Airmen. How interested? 30 million dollars interested. The government has issued 30 million dollars to the Department of Defense as well as the NCAA to collaborate on a long-term research study to evaluate the brains of their cadets and the collegiateRead More
Concussion Detection Goggles
The University of Miami researchers have begun the process of collecting baseline data from their men’s football, women’s soccer, and women’s volleyball teams through a new technology: concussion detection goggles. Dr. Michael Hoffer, a former US Navy captain and current professor at UM, developed the examination technology during his time in Iraq. The athlete’s baselineRead More
If We Don’t Ask, We Don’t Know: Domestic Violence Head Injury
Head injuries have been making headlines these past several months following stories involving veterans who’ve suffered bomb blasts, NFL players who take on-field hits, even the comedian Tracy Morgan following his motor vehicle accident. Unfortunately, we may only have scratched the surface in identifying all of the many populations who may have a history of headRead More
Anatomy of Blast-Induced Head Trauma
Educational materials handed to patients diagnosed with a brain injury almost always show the same thing – a cut-away drawing of person’s head, striking a wall. In the drawing, large arrows show how the brain moves back and forth inside the skull, also known as contre-coup, French for ‘against sudden.’ The drawing illustrates that, afterRead More
Patients with Mild TBI Increased Risk of Mortality
Patients with a history of mild traumatic brain injury (mTBI) are at a 4.2-times greater risk of death than the general population, according to research out of Scotland. By way of background, prior research has shown higher mortality rates among patients with severe head injuries, but little is known about mortality rates among patients mTBI.Read More
Neurodegeneration and Military mTBI
Most active military members who have seen combat have also faced mTBI’s. These mTBI’s are caused by improvised explosive devices (IED); the explosion can cause serious damage if the soldier is close to the explosion. However, recent studies have shown that the soldier only needs to be close enough for the shock waves to travelRead More
Accrual of MRI white matter abnormalities in elderly with normal and impaired mobility
White matter signal abnormality (WMSA) is often present in the MRIs of older persons with mobility impairment. We examined the relationship between impaired mobility and the progressive accrual of WMSA. Mobility was assessed with the Short Physical Performance Battery (SPPB) and quantitative measures of gait and balance. Fourteen subjects had baseline and follow-up MRI scans performed 20Read More
Quantitative Analysis of MRI Signal Abnormalities of Brain White Matter With High Reproducibility and Accuracy
Purpose: To assess the reproducibility and accuracy compared to radiologists of three automated segmentation pipelines for quantitative magnetic resonance imaging (MRI) measurement of brain white matter signal abnormalities (WMSA). Materials and Methods: WMSA segmentation was performed on pairs of whole brain scans from 20 patients with multiple sclerosis (MS) and 10 older subjects who were positioned and imaged twice within 30Read More
Frequency-dependent responses exhibited by multiple regions in human auditory cortex
Recordings in experimental animals have detailed the tonotopic organization of auditory cortex, including the presence of multiple tonotopic maps. In contrast, relatively little is known about tonotopy within human auditory cortex, for which even the number and location of tonotopic maps remains unclear. The present study begins to develop a more complete picture of cortical tonotopic organization inRead More
Object-related activity revealed by functional magnetic resonance imaging in human occipital cortex
The stages of integration leading from localfeature analysis to object recognition were explored in human visual cortex by using the technique of functional magnetic resonance imaging. Here we report evidence for object-related activation. Such activation was located at the lateral-posterior aspect of the occipital lobe, just abutting the posterior aspect of the motion-sensitive area MT/V5, in a region termed the lateralRead More
