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.

Number of color-sensitive cones in the human retina differs dramatically among people

First-ever images of living human retinas have yielded a surprise about how we perceive our world.

Antisense molecules may hold promise in treating brain chemical problems such as Alzheimer's

Saint Louis University research shows a new class of drugs may hold promise in treating brain chemical problems such as Alzheimer's disease, says the principal investigator of research published in an early on-line version of Peptides.

Fndings shed some light on the brain mechanisms involved in schizophrenia

Scientists have discovered that schizophrenia sufferers are not fooled by a visual illusion and are able to judge it more accurately than non-schizophrenic observers.

St. John's wort plant has the capacity to inhibit expression of the HIV-1 gene

A novel protein, p27SJ, extracted from a callus culture of the St. John's wort plant (Hypericum perforatum) suppresses HIV-1 expression and inhibits its replication, according to researchers at Temple University School of Medicine's department of neuroscience and Center for Neurovirology (CNV).

NK-1 receptor antagonists very effective at reducing vomiting after surgery

The results of a new Phase III clinical trial have demonstrated that a new class of drugs, called "NK-1 receptor antagonists," is more effective at reducing vomiting after surgery than the most commonly used drug, according to the Duke University Medical Center researchers who led the trial.

Research has important implications for autism

New research from Melbourne's Howard Florey Institute helps to explain why children with autism spectrum disorders (autism) have problem-solving difficulties.

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.

Early nerve damage caused by repetitive strain injuries can trigger "sick worker" syndrome

...characterized by malaise, fatigue and depression, and often mistaken for poor performance, according to a study by Ann Barr, Ph.D., and Mary Barbe, Ph.D., at Temple University's College of Health Professions.

Canada province will seize children of drug addicts

Canadian province Alberta wants to be able to remove children from the homes of parents who recklessly abuse drugs or are involved in selling them.

FDA approves first transplant of fetal stem cells into human brains

The U.S. Food and Drug Administration has approved the first transplant of fetal stem cells into human brains, a procedure that if successful could pave the way to treating a host of neural disorders.

Possible new directions for treatments for addiction to cocaine

Cocaine causes specific alterations in the brain's circuitry at a genetic level, including short-term changes that result in a high from the cocaine, as well as long-term changes seen in addiction, researchers from UT Southwestern Medical Center have found.

C. elegans, free-living soil nematodes, pave way for better anesthetics

Ten genes that may make patients more or less susceptible to a common anesthetic agent have been identified by researchers using tiny worms and sophisticated technology that eliminates the activity of individual genes.

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.

Protein Oct-6 is not a biological marker for schizophrenia

The protein Oct-6 is not a biological marker for schizophrenia. The results of a study published today in the open access journal BMC Psychiatry contradict previous findings and show that Oct-6, a protein involved in neurodevelopment, is normally expressed in the adult brain and cannot be used to identify patients with schizophrenia.

New device offers potential for accurate and reliable monitoring of brain oxygenation during cardiac surgeries

A new device that uses near-infrared light to non-invasively monitor the oxygenation of the brain during surgery appears to be a promising alternative to the more invasive techniques currently in use, according to a new study by Duke University Medical Center anesthesiologists.

Deep brain stimulation can lower blood pressure

The possibility of a patient lowering their blood pressure at the flick of a switch has been raised by research led by Oxford University, which shows that stimulating parts of the brain with electrodes can change a patient’s blood pressure.

Diabetes drugs may also prevent nerve degeneration caused by Alzheimer's disease

Recent research has shown a surprising link between Alzheimer’s and diabetes, two of the major health challenges facing society today. According to Dr Holscher modern lifestyle promotes the development of type 2 diabetes, which in turn could drastically increase the number of people to develop Alzheimer’s disease as people with type 2 diabetes are much more likely to develop the disease than healthy people of the same age.

Better knowledge of how the mechanism explaining alcohol addiction works

Alcohol, like any other substance that reinforces behaviour, such as another drug of abuse or even food, has a certain capacity to enhance social memory, that is, the ability to remember other individuals. If a mouse is administered alcohol immediately after being introduced to another animal of its own kind, the former will recognise the latter sooner.

Researchers discover the presence of functional ion channels in human embryonic stem cells

These ion channels act like electrical wires and permit ESCs, versatile cells that possess the unique ability to become all cell types of the body, to conduct and pass along electric currents.
