The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.

New, more targeted way to stimulate neurons in the brain

By harnessing quantum dots—tiny light-emitting semiconductor particles a few billionths of a meter across—researchers at the University of Washington (UW) have developed a new and vastly more targeted way to stimulate neurons in the brain.

Positive emotional experience induces people to visit social networking sites

People visit social networking sites such as Facebook for many reasons, including the positive emotional experience that people enjoy and want to repeat, according to an article in Cyberpsychology, Behavior, and Social Networking, a peer-reviewed journal published by Mary Ann Liebert, Inc..

Thumb and little finger react faster than the middle finger

The fingers on the outside - i.e. the thumb and little finger - therefore react faster than the middle finger, which is exposed to the "cross fire" of two neighbours on each side. Through targeted learning, this speed handicap can be compensated. The working group led by PD Dr. Hubert Dinse (Neural Plasticity Lab at the Institute for Neuroral Computation) report in the current issue of PNAS.

Center for LAM Research and Clinical Care at BWH to conduct phase I combination drug trial

The Center for LAM Research and Clinical Care at Brigham and Women's Hospital (BWH) has been awarded a $1 million plus, four-year grant from the U.S. Department of Defense Office of the Congressionally Directed Medical Research Programs to fund their work on lymphangioleiomyomatosis.

Researchers discover function and expression of CD97 in malignant gliomas

Researchers at Virginia Commonwealth University Medical Center's VCU Massey Cancer Center and Harold F. Young Neurosurgical Center and Old Dominion University have discovered that suppression of Wilms tumor 1 protein (WT1) results in downregulation of CD97 gene expression in three glioblastoma cell lines and reduces the characteristic invasiveness exhibited by glial tumor cells.

MRI techniques can measure changes in microstructural properties of white matter

Innovative magnetic resonance imaging (MRI) techniques that can measure changes in the microstructure of the white matter likely to affect brain function and the ability of different regions of the brain to communicate are presented in an article in the groundbreaking new neuroscience journal Brain Connectivity, a bimonthly peer-reviewed publication from Mary Ann Liebert, Inc.

Scientists reveal how psychostimulant drugs work to control hyperactivity

It has long been known that psychostimulant drugs have the paradoxical effect of reducing hyperactivity. [Psychostimulant drugs include methylphenidate - known by the trade names Ritalin, Concerta, and Methylin - and methamphetamine]. Since the mid-1950s, millions of children and adults have been prescribed stimulant medications to control attention deficit hyperactivity disorder.

Padded gloves and headgear can help protect young fighters

The use of padded headgear and gloves reduces the impact that fighters absorb from hits to the head, according to newly published research from Cleveland Clinic.

Researchers discover how mutations in parkin gene cause PD

Parkinson's disease researchers at the University at Buffalo have discovered how mutations in the parkin gene cause the disease, which afflicts at least 500,000 Americans and for which there is no cure.

Scientists discover how individual MST neurons function

When you are about to collide into something and manage to swerve away just in the nick of time, what exactly is happening in your brain? A new study from the Montreal Neurological Institute and Hospital - The Neuro, McGill University shows how the brain processes visual information to figure out when something is moving towards you or when you are about to head into a collision.

Smoking leads to early cognitive decline: Study

There is growing evidence that using cigarettes can also affect the brain: the latest study shows that smoking is associated with cognitive decline as early as age 45, and that male smokers may be more vulnerable to these mental effects than women.

Spanking kids does not work and may lead to developmental difficulties

The authors say the medical finding have been largely overlooked and overshadowed by concerns that parents should have the right to determine how their children are disciplined.

ECNP expresses deep concern at withdrawal by AstraZeneca from neuroscience drug research

The European College of Neuropsychopharmacology expresses its deep concern at the recently announced withdrawal by AstraZeneca from neuroscience drug research. AstraZeneca's pull-out is especially disturbing given that it follows a series of similar withdrawals in the last two years by major pharmaceutical companies. There is a growing sense that neuroscience in Europe is now facing a severe crisis.

Inhibiting MET signaling in glioblastoma has major therapeutic value

A recent discovery by Van Andel Research Institute (VARI) scientists enables the prediction of patient sensitivity to proposed drug therapies for glioblastoma - the most common and most aggressive malignant brain tumor in humans.

Visual working memory not as specialized in the brain as visual encoding

Researchers have long known that specific parts of the brain activate when people view particular images. For example, a region called the fusiform face area turns on when the eyes glance at faces, and another region called the parahippocampal place area does the same when a person looks at scenes or buildings. However, it's been unknown whether such specialization also exists for visual working memory, a category of memory that allows the brain to temporarily store and manipulate visual information for immediate tasks.

Study to understand how brain processes information in competitive settings

Researchers have found a way to study how our brains assess the behavior - and likely future actions - of others during competitive social interactions. Their study, described in a paper in the Proceedings of the National Academy of Sciences, is the first to use a computational approach to tease out differing patterns of brain activity during these interactions, the researchers report.
