Researchers find gamma-secretase modulators being tested for Alzheimer’s work in unexpected and beneficial ways

Researchers at Mayo Clinic, with their national and international collaborators, have discovered how a class of agents now in testing to treat Alzheimer's disease work, and say they may open up an avenue of drug discovery for this disease and others.

Did you ever wonder why it is so difficult to part with your stuff?

A new study reveals fascinating insights into the specific neuropsychological mechanisms that are linked with the potential loss of possessions.

People with tune deafness able to detect a wrong note unconsciously

People with tune deafness aren't able to tell when a musician accidentally strikes the wrong note in a song, but their brains know the difference. Researchers from the National Institute on Deafness and Other Communication Disorders (NIDCD), part of the National Institutes of Health, have found that people with tune deafness, an auditory processing disorder in which a person with normal hearing has trouble distinguishing notes in a melody, are able to detect a wrong note unconsciously.

Researchers show brain can protect against cancer

Scientists have been aware for many years that if cancer patients are not able to deal with the stress associated with being sick, the cancer will progress faster than in calmer patients.

Scientists closer to solving epilepsy mystery

Scientists in the United States believe they are a step closer to understanding why some people suffer from epileptic fits.

Nose stem cells used to treat Parkinson's

Scientists in Queensland, Australia have made a major breakthrough in research into Parkinson's disease.

Complex synapses drove brain evolution

One of the great scientific challenges is to understand the design principles and origins of the human brain. New research has shed light on the evolutionary origins of the brain and how it evolved into the remarkably complex structure found in humans.

Human stem cells show promise against fatal children's diseases

Scientists have used human stem cells to dramatically improve the condition of mice with a neurological condition similar to a set of diseases in children that are invariably fatal, according to an article in the June issue of the journal Cell Stem Cell.

You may not be what you eat after all!

A new study shows that increased eating does not necessarily lead to increased fat. The finding in the much-studied roundworm opens the possibility of identifying new targets for drugs to control weight, the researchers say.

New clues for nerve cell repair

A new study at the Montreal Neurological Institute at McGill University identifies a key mechanism for the normal development of motor nerve cells (motor neurons) - cells that control muscles. This finding is crucial to understanding and treating a range of conditions involving nerve cell loss or damage, from spinal cord injury to neurodegenerative diseases such as ALS, also known as Lou Gehrig's disease.

Flow of potassium ions in brain cells is key to sexual arousal

When it comes to sex, a female rat knows how to avoid a communication breakdown. To announce her sexual readiness, she will automatically arch her back, deflect her tail and stand rigid to allow an aroused male to mount.

Yale researchers block transforming growth factor to clear up amyloid plaques in mice

Blocking a common immune system response cleared up plaques associated with Alzheimer's Disease and enabled treated mice to recover some lost memory, Yale University researchers report Friday in the journal Nature Medicine.

New insight into the genetics of Lou Gehrig's disease

An upcoming paper from Drs. Hidenori Ichijo and Hideki Nishitoh (The University of Tokyo) and colleagues lends new and valuable insight into the genetics of ALS.

Rett syndrome gene found to be full of surprises

A study funded by the National Institutes of Health (NIH) has transformed scientists' understanding of Rett syndrome, a genetic disorder that causes autistic behavior and other disabling symptoms. Until now, scientists thought that the gene behind Rett syndrome was an "off" switch, or repressor, for other genes. But the new study, published today in Science, shows that it is an "on" switch for a startlingly large number of genes.

Timer genes control brain size

Experiments using fruit flies have helped a team at the MRC National Institute for Medical Research to identify genes that control how large the developing brain becomes.

Scientists identify a brain mechanism underlying persistent cocaine craving

Scientists have identified a mechanism in the brain that helps to explain why craving for cocaine, and the risk of relapse, seems to increase in the weeks and months after drug use is stopped. The research was supported by the National Institute on Drug Abuse (NIDA), part of the National Institutes of Health.

Molecular fingerprint of cocaine addiction revealed

The first large-scale analysis of proteins in the brains of monkeys addicted to cocaine reveals new information on how long-term cocaine use changes the amount and activity of various proteins affecting brain function.

New insights into the neural circuitry of trust

The brain centers triggered by a betrayal of trust have been identified by researchers, who found they could suppress such triggering and maintain trust by administering the brain chemical oxytocin. The researchers said their findings not only offer basic insights into the neural machinery underlying trust; the results may also help in understanding the neural basis of social disorders such as phobias and autism.

Discovery of a molecular scaffold that guides connections between brain cells

Brain cells known as neurons process information by joining into complex networks, transmitting signals to each other across junctions called synapses. But "neurons don't just connect to other neurons," emphasizes Z. Josh Huang, Ph.D., "in a lot of cases, they connect to very specific partners, at particular spots."

Discovery of protein key to neuro-regeneration

Researchers at the Peninsula Medical School in the South West of England, University College London, the San Raffaele Scientific Institute in Milan and Cancer Research UK, have for the first time identified a protein that is key to the regeneration of damage in the peripheral nervous system and which could with further research lead to understanding diseases of our peripheral nervous systems and provide clues to methods of repairing damage in the central nervous system, according to a paper published this week in the Journal of Cell Biology.
