Disconnection between the default mode network and medial temporal lobes in post-traumatic amnesia
See Bigler (doi:10.1093/aww277) for a scientific commentary on this article. Post-traumatic amnesia is very common immediately after traumatic brain injury. It is characterized by a confused, agitated state and a pronounced inability to encode new memories and sustain attention. Clinically, post-traumatic amnesia is an important predictor of functional outcome. However, despite its prevalence and functional importance, the pathophysiology of post-traumatic amnesia is not understood. Memory processing relies on limbic structures such as the hippocampus, parahippocampus and parts of the cingulate cortex. These structures are...

Mapping Traumatic Brain Injuries
There's been an increasing amount of media attention to the topic of Traumatic Brain Injury (TBI) -bolstered in part by conversations surrounding the 2015 Hollywood blockbuster Concussion. The movie Concussion describes a particular phenomenon, Chronic Traumatic Encephalopathy or CTE, which occurs in the brain after repeated high impact blows to the head. The diagnosis of CTE requires examining brain tissue under a microscope after death, so it can't be diagnosed in living individuals. But in fact, there are many types of TBI, with concussion being the mildest (but most common) form. Today, brain mapping techniques are mak...

The Day That Went Missing: A First-Person Account of Transient Global Amnesia
In this vivid first-person case history, political reporter Trip Gabriel describes experiencing a classic episode of transient global amnesia. He was near the average target age of 61. Although no cause has been established for the syndrome, as with many other patients his episode appears to have been triggered by contact with water: He was racing a sailboat. While remaining alert and handling complex sailing maneuvers, he suddenly developed amnesia that left him with no recollection of finishing two races, returning to shore, drinking a beer with his friends, needing help finding his car, and not knowing where he was or w...

The Medical Emergency Of Otto Warmbier
All that the doctors who treated Cincinnati, Ohio resident Otto Warmbier knew is what they had seen or maybe read in the news. They knew he had just been released on June 13 from imprisonment in North Korea where he had been held by for more than 17 months. He had been sentenced in March 2016 to 15 years of hard labor for allegedly removing a propaganda poster from a wall at a Pyongyang hotel where he had been staying. The University of Virginia honors student had been visiting the authoritarian state during a five-day trip with a group called Young Pioneer Tours, which is a group out of China – an important note. Ot...

Functional connectivity between somatosensory and motor brain areas predicts individual differences in motor learning by observing
Action observation can facilitate the acquisition of novel motor skills; however, there is considerable individual variability in the extent to which observation promotes motor learning. Here we tested the hypothesis that individual differences in brain function or structure can predict subsequent observation-related gains in motor learning. Subjects underwent an anatomical MRI scan and resting-state fMRI scans to assess preobservation gray matter volume and preobservation resting-state functional connectivity (FC), respectively. On the following day, subjects observed a video of a tutor adapting her reaches to a novel for...

First ‐aid training in school: amount, content and hindrances
This study aimed to establish how much time is spent on first‐aid training, which first‐aid measures are taught, and which factors prevent teachers from providing the quantity and quality of first‐aid training that they wish to give. MethodsA questionnaire was distributed to teachers in physical education in primary and secondary schools and to teachers in vocational subjects in higher secondary schools. ResultsThe teachers taught a median of two lessons in first aid per year. Cardiopulmonary resuscitation (CPR) was taught by 64% of teachers, free airway and recovery position by 69% and stopping severe bleeding by 51...

Impact of Asynchronous Training on Radiology Learning Curve among Emergency Medicine Residents and Clerkship Students.
CONCLUSION: Incorporating asynchronous WBL modules into EM clerkship and residency curriculum provides early radiographic exposure in their clinical training and can enhance diagnostic head CT scan interpretation. PMID: 29272248 [PubMed - in process]

Cancers, Vol. 11, Pages 111: A Review on a Deep Learning Perspective in Brain Cancer Classification
uca Saba Jasjit S. Suri A World Health Organization (WHO) Feb 2018 report has recently shown that mortality rate due to brain or central nervous system (CNS) cancer is the highest in the Asian continent. It is of critical importance that cancer be detected earlier so that many of these lives can be saved. Cancer grading is an important aspect for targeted therapy. As cancer diagnosis is highly invasive, time consuming and expensive, there is an immediate requirement to develop a non-invasive, cost-effective and efficient tools for brain cancer characterization and grade estimation. Brain scans using magnetic resonanc...

Collectivism Is Associated With Greater Neurocognitive Fluency in Older Adults
This study aimed to evaluate the impact of self-construal on neurocognitive functions in older adults. A total of 86 community-dwelling older adults 60 years and older were assessed with three common self-report measures of self-construal along individualism and collectivism (IC). A cognitive battery was administered to assess verbal and non-verbal fluency abilities. Latent profile analysis (LPA) was used to categorize individuals according to IC, and one-way analyses of covariance (ANCOVA), including relevant covariates (e.g., ethnicity, gender, linguistic abilities), were used to compare neurocognitive functions between ...
