Tale of the Good and the Bad Cdk5: Remodeling of the Actin Cytoskeleton in the Brain
AbstractCdk5 kinase, a cyclin-dependent kinase family member, is a key regulator of cytoskeletal remodeling in the brain. Cdk5 is essential for brain development during embryogenesis. After birth, it is essential for numerous neuronal processes such as learning and memory formation, drug addiction, pain signaling, and long-term behavior changes, all of which rely on rapid alterations in the cytoskeleton. Cdk5 activity is deregulated in various brain disorders including Alzheimer ’s disease, Parkinson’s disease, amyotrophic lateral sclerosis, and ischemic stroke, resulting in profound remodeling of the neuronal cytoskel...

The anatomy of apathy: a neurocognitive framework for amotivated behavior
Publication date: Available online 8 July 2017 Source:Neuropsychologia Author(s): C. Le Heron, M.A.J. Apps., M. Husain Apathy is a debilitating syndrome associated with many neurological disorders, including several common neurodegenerative diseases such as Parkinson's disease and Alzheimer's disease, and focal lesion syndromes such as stroke. Here, we review neuroimaging studies to identify anatomical correlates of apathy, across brain disorders. Our analysis reveals that apathy is strongly associated with disruption particularly of dorsal anterior cingulate cortex (dACC), ventral striatum (VS) and connected brain region...

UCLA neuroscientists use weak electrical signal to stimulate human brain and improve memory
FINDINGSNeuroscientists at the  David Geffen School of Medicine at UCLA have discovered precisely where and how to electrically stimulate the human brain to enhance people’s recollection of distinct memories. People with epilepsy who received low-current electrical pulses showed a significant improvement in their ability to recognize specific faces and ignore simila r ones.Eight of nine patients ’ ability to recognize the faces of specific people improved after receiving electrical pulses to the right side of the brain’s entorhinal area, which is critical to learning and memory. However, electrical stimulation deli...

Epilepsy as a Network Disorder (1): What can we learn from other network disorders such as autistic spectrum disorder and mood disorders?
Publication date: Available online 26 October 2017 Source:Epilepsy & Behavior Author(s): Andres M. Kanner, Helen Scharfman, Nathalie Jette, Evdokia Anagnostou, Christophe Bernard, Carol Camfield, Peter Camfield, Karen Legg, Ilan Dinstein, Peter Giacobe, Alon Friedman, Bernd Pohlmann-Eden Epilepsy is a neurologic condition which often occurs with other neurologic and psychiatric disorders. The relation between epilepsy and these conditions is complex. Some population-based studies have identified a bidirectional relation, whereby not only patients with epilepsy are at increased risk of suffering from some of these ...

Can Fish Oil Help Reading?
Discussion Fats and fatty acids are essential for good human health. Saturated fats have hydrogen pairs linked to each carbon on the carbon backbone. They are solid or semi-solid at room temperature. Common examples are butter, lard, or hardened vegetable shortening. They are linked to higher cholesterol and triglycerides and only a small amount of them are recommended to be consumed in the diet. Unsaturated fats have one or more hydrogen atoms missing from the carbon backbone. They are liquid at room temperature. Monounsaturated fatty acids have one hydrogen pair that is missing from the carbon backbone. They are liq...

Neuroscientists show deep brain waves occur more often during navigation and memory formation
FINDINGSUCLA neuroscientists are the first to show that rhythmic waves in the brain called theta oscillations happen more often when someone is navigating an unfamiliar environment, and that the more quickly a person moves, the more theta oscillations take place — presumably to process incoming information faster.In an unexpected finding, theta oscillations were most prominent in a blind person who relied on a cane to move. The scientists hypothesized that a sightless person explores a strange environment through multiple senses, which would require more brain activity to process the extra sensory input.BACKGROUNDTheta o...

UCLA biologists ‘transfer’ a memory
UCLA biologists report they have transferred a memory from one marine snail to another, creating an artificial memory, by injecting RNA from one to another. This research could lead to new ways to lessen the trauma of painful memories with RNA and to restore lost memories.“I think in the not-too-distant future, we could potentially use RNA to ameliorate the effects of Alzheimer’s disease or post-traumatic stress disorder,” said David Glanzman, senior author of the study and a UCLA professor of integrative biology and physiology and of neurobiology. The team’sresearch is published May 14 in eNeuro, the online journa...

Effect of Edible Bird's Nest Extract on Lipopolysaccharide-Induced Impairment of Learning and Memory in Wistar Rats.
Authors: Careena S, Sani D, Tan SN, Lim CW, Hassan S, Norhafizah M, Kirby BP, Ideris A, Stanslas J, Bin Basri H, Lim CTS Abstract Cognitive disability is a common feature associated with a variety of neurological conditions including Alzheimer's Disease (AD), Parkinson's Disease (PD), brain injury, and stroke. Emerging evidence has demonstrated that neuroinflammation plays an important role in the development of cognitive impairment. Current available therapies are relatively ineffective in treating or preventing cognitive disabilities, thus representing an important, unfulfilled medical need. Hence, developing pot...

Should You Take Aspirin Every Day? Here ’s What the Science Says
Aspirin is best known as an over-the-counter painkiller. But acetylsalicylic acid, as it’s called chemically, has many other health benefits, as well as side effects, in the body that have only become clear in recent years. Here’s what the latest science says about the health benefits and side effects of aspirin, as well as which conditions it may treat and those it doesn’t appear to improve. (If you are taking aspirin for any reason other than for periodic pain relief, it’s best to consult with your doctor to confirm whether the benefits outweigh the risks in your particular case.) How aspirin affe...

The 12-Word Philadelphia Verbal Learning Test Performances in Older Adults: Brain MRI and Cerebrospinal Fluid Correlates and Regression-Based Normative Data
Conclusion: The PVLT appears sensitive to markers of neurodegeneration, including temporal regions affected by AD. Conversely, in cognitively normal older adults, PVLT performance seems to relate to white matter disease and axonal injury, perhaps reflecting non-AD pathways to cognitive change. Enhanced normative data enrich the clinical utility of this tool.Dement Geriatr Cogn Disord Extra 2018;8:476 –491

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 ...
