The concept of cognitive reserve (CR); most commonly estimated through the use of ‘proxies’ such as years of education (YoE); addresses inter-individual differences in the adaptability and susceptibility of cognitive abilities or day-to-day function to brain aging, pathology or insult. Neuroimaging studies of cognitively normal older individuals have revealed positive associations between CR proxies and…
A new paper published in Nature Reviews Neurology suggests that recent advances in deep brain stimulation (DBS); for Parkinson’s disease could lead to treatments for conditions such as obsessive-compulsive disorder (OCD); Gilles de la Tourette syndrome and depression. The authors of the paper, from the Geneva University Hospitals (HUG); the University of Geneva, University of Tübingen…
The human brain is the central organ of the human nervous system, and with the spinal cord makes up the central nervous system. The brain consists of the cerebrum, the brainstem, and the cerebellum. It controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sense organs. The Stentrode is a device that is placed inside a blood vessel…
A new method of graphic representation of neurons that allows us to visualize the data developed by neuroscientists. A team of researchers from Universidad Politécnica de Madrid (UPM); Universidad Rey Juan Carlos (URJC) and the Cajal Institute (IC) -from the Spanish National Research Council (CSIC); has developed a new model of symbolic representation of neurons…
Sensory and movement disturbances have also reported, including imbalance, tremors, vertigo, dizziness; electric-shock-like experiences in the brain, often described by people who have them as “brain zaps“. A new study has shown that zapping the brains of people over the age of 60 can help improve their memory; cognitive functions to function as if they…
Autism is a complex neurobehavioral condition that includes impairments in social interaction and developmental language and communication skills combined with rigid, repetitive behaviors. Because of the range of symptoms, this condition is now autism spectrum disorder (ASD). It covers a large spectrum of symptoms, skills, and levels of impairment. ASD ranges in severity from a…
A first-of-its-kind national study has found that a form of brain imaging that detects Alzheimer’s-related “plaques”; significantly influenced clinical management of patients with mild cognitive impairment and dementia. The study revealed that providing clinicians with the results of positron emission tomography (PET); scans that identify amyloid plaques in the brain changed medical management including the…
A new University of Virginia study proves that a damaged peripheral nervous system is capable of repairing itself when healthy cells are there from the central nervous system. The finding has implications for the future treatment of debilitating and life-threatening nervous system disorders affecting children; such as muscular dystrophy, Guillain-Barre Syndrome and Charcot-Marie-Tooth Disease. Oligodendrocytes…
Neuroscientists at the new animal model of schizophrenia that will enable researchers around the world to better understand the disease and develop new treatments. Schizophrenia, which affects around 7 people in 1000; is a poor understanding group of mental disorders that disrupt cognition and behavior. Common hallmarks include delusions, hallucinations, and difficulty perceiving reality. The…
Korea Brain Research Institute (KBRI, President Pann Ghill Suh) announced on that its research team led by principal researcher Yoichi Kosodo developed technology to mass produce cerebral cortex neurons utilizing Induced Pluripotent Stem Cells (iPS). iPS(Induced Pluripotent Stem Cells); They are stem cells of somatic cells; which do not have ethical problems. Cerebral cortex: Cerebral…
A mathematical model is a description of a system using mathematical concepts and language. The process of developing a mathematical model is termed mathematical modeling. Mathematical models are used in the natural sciences (such as physics, biology, earth science, chemistry); engineering disciplines (such as computer science, electrical engineering); as well as in the social sciences (such as economics, psychology, sociology, political science).…
A new article explores the pathophysiological factors that link sleep disturbances and Alzheimer’s disease. The better understanding of this connection may lead to potential diagnostics and therapeutics for Alzheimer’s disease and other neurodegenerative diseases and dementia. The article in the Journal of Neurophysiology. Alzheimer’s research has largely focused on the presence of two proteins amyloid…
