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.

Patients with Parkinson's develop artistic talents after dopamine-inducing therapy

Parkinson's experts across the world have been reporting a remarkable phenomenon - many patients treated with drugs to increase the activity of dopamine in the brain as a therapy for motor symptoms such as tremors and muscle rigidity are developing new creative talents, including painting, sculpting, writing, and more.

Study explains how Timothy syndrome mutation causes wiring defects that underlie cognition

A new finding in neuroscience for the first time points to a developmental mechanism linking the disease-causing mutation in an autism-related disorder, Timothy syndrome, and observed defects in brain wiring, according to a study led by scientist Ricardo Dolmetsch and published online yesterday in Nature Neuroscience.

Aggressive breast cancer’s metastasis molecular switch identified

Scientists at Weill Cornell Medical College have discovered the molecular switch that allows aggressive triple negative breast cancer cells to grow the amoeba-like protrusions they need to crawl away from a primary tumor and metastasize throughout the body. Their findings, published in Cancer Cell, suggest a novel approach for developing agents to treat cancer once it has spread.

Bionic devices: an interview with Dr Rylie Green

Bionic devices are implants which replace biological functions which have been lost due to nerve damage. They use electrical signals to stimulate the remaining nerve cells following disease or injury. Although the term bionic was only coined in the late 1950s, the earliest bionic devices were cardiac pacemakers, developed in the early 1900s. However the first commercial implantable units were not available until the 1950s.

New rehabilitation system improves QOL for people with brain damage

The Biomechanics Institute of Valencia (IBV) is currently taking part in the European project WALKX with the aim of developing an innovative rehabilitation system to improve the quality of life of people who have suffered brain damage. This system will allow home rehabilitation and improve patient's autonomy.

BGI-Shenzhen, CHOP to collaborate on research into pediatric brain tumors

The Children's Hospital of Philadelphia (CHOP) and BGI-Shenzhen today announced a formal agreement to collaborate on research into next-generation sequencing and analysis of pediatric brain tumors, in support of the Childhood Brain Tumor Tissue Consortium (CBTTC).

Repression of PTB protein in fibroblasts can convert pluripotent stem cells into functional neurons

Repression of a single protein in ordinary fibroblasts is sufficient to directly convert the cells - abundantly found in connective tissues - into functional neurons. The findings, which could have far-reaching implications for the development of new treatments for neurodegenerative diseases like Huntington's, Parkinson's and Alzheimer's, will be published online in advance of the January 17 issue of the journal Cell.

Blocking interaction of JNK enzyme may counteract neuron destruction

Oxidative stress is a primary villain in a host of diseases that range from cancer and heart failure to Alzheimer's disease, Amyotrophic Lateral Sclerosis and Parkinson's disease.

Lower liver quality from donation after cardiac death linked to drop in transplants

A new study, funded in part by the National Institutes of Health (NIH) and Health Resources and Services Administration, and published in the January 2013 issue of Liver Transplantation, a journal of the American Association for the Study of Liver Diseases (AASLD), found that the non-use of donor livers climbed through 2010 due to a worsening of donor liver quality, primarily from donation following cardiac death. Diabetes, donor age, and body mass index (BMI) were also linked to a decrease in use of organs.

DESI technique identifies cancer type, grade and tumor margins in brain surgery patients

A new tool that could allow for faster, more comprehensive testing of brain tissue during surgery successfully identified the cancer type, grade and tumor margins in five brain surgery patients, according to a Purdue University and Brigham and Women's Hospital study.

Longer looks: A key Hagel mission is to cut military health costs; Medical lessons from a mother's death; How they price - and how we pay for -a $300,000 medicine

As David Brooks and Paul Wolfowitz and many others have shown, it's easy to frame our messy fiscal conundrum in these simple terms of guns vs. butter, or rather, guns vs grandma's buttery-yellow, super-pricey heart medication.
