Scientists discover how to integrate new neurons into the brain

In experiments with mice, scientists from Johns Hopkins' Institute for Cell Engineering have discovered the steps required to integrate new neurons into the brain's existing operations.

Stem cells provide new way to sneak drugs into brain

One of the great challenges for treating Parkinson's diseases and other neurodegenerative disorders is getting medicine to the right place in the brain.

Eye cell implants improve lives of Parkinson's sufferers

U.S. researchers say that people with Parkinson's disease showed a marked improvement after surgeons implanted in their brains chemical-producing cells taken from the eye of a dead donor.

Cocaine abuse may increase risk of Parkinson's disease

Adults who abuse cocaine might increase their risk of developing Parkinson's disease (PD), and pregnant women who abuse cocaine could increase the risk of their children developing PD later in life, according to results of laboratory studies performed by investigators at St. Jude Children's Research Hospital.

Genetic testing for Parkinson disease, is there a point?

Should we start being genetically tested for Parkinson’s disease (PD)? According to research just published in the December issue of the "journal Movement Disorders" this might be a possibility in the future if you belong to a family affected by G2019S, a genetic mutation responsible for some PD cases.

Now we know - love is the drug you can't forget!

According to researchers at Florida State University who were examining the nature of love it may really, as the poets say, be better to have loved and lost than never to have loved at all.

Disruption of normal gene interaction linked to schizophrenia

Disruption of the normal interaction between the genes PRODH and COMT contributes directly to major symptoms of schizophrenia by upsetting the balance of the brain chemicals glutamate and dopamine, according to a group of investigators that includes a scientist now at St. Jude Children's Research Hospital.

Protein target for Parkinson's disease

Researchers at Johns Hopkins' Institute for Cell Engineering (ICE) have discovered a protein that could be the best new target in the fight against Parkinson's disease since the brain-damaging condition was first tied to loss of the brain chemical dopamine.

Coaxing human embryonic stem cells to make dopamine

For all of the promise embryonic stem cells hold for therapies for neurodegenerative diseases such as Parkinson's disease, they are notoriously difficult to use.

Lowering calorie intake may help Parkinson's disease

A new Oregon Health & Science University and Portland Veterans Affairs Medical Center study suggests that early-stage Parkinson's disease patients who lower their calorie intake may boost levels of an essential brain chemical lost from the neurodegenerative disorder.

New drug far more effective in stopping smokers lighting up

An experimental smoking cessation drug by Pfizer apparently gives smokers better odds at kicking the habit.

Change in neurons' responsiveness marks newly formed sensory associations during learning

During our waking hours, our brains are inundated with sensory information that shifts from one moment to the next.

How the brain tracks time is essential to understanding all its functions

The brain is a "time machine," assert Duke neuroscientists Catalin Buhusi and Warren Meck. And understanding how the brain tracks time is essential to understanding all its functions. The brain's internal clocks coordinate a vast array of activities from communicating, to orchestrating movement, to getting food, they said.

Environment is a major factor influencing the success of the addiction recovery

New research in monkeys suggests that, although living in an "enriched" environment can make someone less vulnerable to abusing cocaine, once started, extended drug abuse can eliminate the social advantage the abuser originally had.

Faulty gene may identify those at risk of schizophrenia

Scientists believe they have discovered a genetic defect which could help explain the biological basis of schizophrenia.

Teens with missing part of a chromosome confirm genetic role in schizophrenia

A study in youth who are missing part of a chromosome is further implicating a suspect gene in schizophrenia.

Dopamine link to psychiatric and neurological disorders

A gene that regulates dopamine levels in the brain is involved in the development of schizophrenia in children at high risk for the disorder, say researchers at the Stanford University School of Medicine, Lucile Packard Children's Hospital and the University of Geneva.

New genetic discovery may help explain why some people develop high blood pressure and others don't

It also gives new insight into how the kidneys govern the balance of salt in the body, a crucial task for regulating blood pressure. And, it reveals how a gene already linked to behavior and mental health can play a role in the body, as well as the brain.

Parkinson's dark period can be minimized or alleviated with the right kind of care

Some people call it "the dark time," the period between when a person is diagnosed with Parkinson's disease and when treatment with medication begins.

Key neural system at risk from prenatal exposure to alcohol

In a study of adult monkeys who were exposed to moderate amounts of alcohol in utero, scientists have found that prenatal exposure to alcohol - even in small doses - has pronounced effects on the development and function later in life of the brain's dopamine system, a critical component of the central nervous system that regulates many regions of the brain.
