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.

Scientists map sensory nerves in mouse skin

Johns Hopkins scientists have created stunning images of the branching patterns of individual sensory nerve cells. Their report, published online in the journal eLife on Dec. 18, details the arrangement of these branches in skin from the backs of mice.

Link made between muscular dystrophy and defective nerve wiring

Working with mice, Johns Hopkins scientists have discovered that a particular protein helps nerve cells extend themselves along the spinal cord during mammalian development. Their results shed light on the subset of muscular dystrophies that result from mutations in the gene that holds the code for the protein, called dystroglycan, and also show how the nerve and muscle failings of the degenerative diseases are related.

AAV-based gene therapy cocktail may help extend lives of children with Canavan disease

Results of a clinical trial that began in 2001 show that a gene therapy cocktail conveyed into the brain by a molecular special delivery vehicle may help extend the lives of children with Canavan disease, a rare and fatal neurodegenerative disorder.

Lou Gehrig's disease may be treatable using neural stem cells

Promising new research provides evidence that ALS, amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, may be treatable using neural stem cells.

NIDA's 2012 Monitoring the Future survey shows rates stable or down for most drugs

Continued high use of marijuana by the nation's eighth, 10th and 12th graders combined with a drop in perceptions of its potential harms was revealed in this year's Monitoring the Future survey, an annual survey of eighth, 10th, and 12th-graders conducted by researchers at the University of Michigan.

Brain structure linked to neuropsychopathology in psychosis patients

Results from an Italian study show that the structural development of key brain regions is associated with neuropsychopathology in patients with first-episode schizophrenia.

Biologic changes after delivery may prevent development of chronic pain

Chronic pain from childbirth is remarkably rare, according to a study from the January issue of Anesthesiology. Additionally, in a second study, researchers at Wake Forest School of Medicine, Winston-Salem, N.C., found the biologic changes after delivery may prevent the development of pain.

Harvard scientists shed new light on olfactory feedback mechanism

More than a century after it was first identified, Harvard scientists are shedding new light on a little-understood neural feedback mechanism that may play a key role in how the olfactory system works in the brain.

Ion channel acts as powerful ‘brake’ after epileptic seizures

Given that epilepsy impacts more than 2 million Americans, there is a pressing need for new therapies to prevent this disabling neurological disorder. New findings from the neuroscience laboratory of Mark S. Shapiro, Ph.D., at The University of Texas Health Science Center at San Antonio, published Dec. 20 in the high-impact scientific journal, Neuron, may provide hope.

Patients achieve favorable seizure outcomes after resective epilepsy surgery

Brain surgery for certain difficult forms of epilepsy often reduces or eliminates seizures for more than 15 years after the procedure, according to new research by neurologists at Henry Ford Hospital.

Studies examine pediatric TBIs treated at Wuhan Children's Hospital from 2002-2011

Traumatic brain injuries (TBIs) among children in China are a growing public health concern. Two new studies by researchers of the International Program at the Center for Injury Research and Policy of The Research Institute at Nationwide Children's Hospital and the Wuhan Children's Hospital in China examined pediatric TBIs that were treated at Wuhan Children's Hospital from 2002 to 2011.

Views on Conn. shootings: Mental illness doesn't generally lead to violence; Need for more treatment options; Helping the survivors

It's possible that preventing people with schizophrenia, bipolar disorder and other serious mental illnesses from getting guns might decrease the risk of mass killings. Even the Supreme Court, which in 2008 strongly affirmed a broad right to bear arms, at the same time endorsed prohibitions on gun ownership "by felons and the mentally ill." But mass killings are very rare events, and because people with mentally illness contribute so little to overall violence, these measures would have little impact on everyday firearm-related killings.

Hospital MRIs may effectively predict long-term outcomes for people with mild TBI

Hospital MRIs may be better at predicting long-term outcomes for people with mild traumatic brain injuries than CT scans, the standard technique for evaluating such injuries in the emergency room, according to a clinical trial led by researchers at the University of California, San Francisco (UCSF) and the San Francisco General Hospital and Trauma Center (SFGH).

Link between silent stroke and Parkinson's disease

Scientists at The University of Manchester have for the first time identified why a patient who appears outwardly healthy may develop Parkinson's disease.

Jagaricin and antifungal drugs: an interview with Prof Christian Hertweck

Most people have already experienced a fungal infection (mycosis) of the outer layer of the skin, athlete’s foot or ringworm. Whereas such infections may be cumbersome and often difficult to cure, usually they are not dangerous. However, in cases where a fungus causes a systemic infection, this is, it infects internal organs such as lungs or brain, the infection may turn into a life-threatening disease. Of course, only pathogenic fungi cause problems and the degree of virulence varies.

High AngII levels put stress on the ER and cause hypertension

When the heart works too hard, the brain may be to blame, says new Cornell University research that is changing how scientists look at high blood pressure (hypertension). The study, published in the Journal of Clinical Investigation in November, traces hypertension to a newfound cellular source in the brain and shows that treatments targeting this area can reverse the disease.
