New insight into how neurons regulate their activity

Neurons communicate by passing electrical messages, known as action potentials, between each other. Each neuron has a highly specialized structural region, the axon initial segment (AIS), whose primary role is in the generation ...

Deciphering the neural code that links food to aging

Diet exerts a major impact on health and ageing. The nervous system plays an important role in this process but, thus far, how food signals are interpreted by the nervous system has been a mystery. This is an important question ...

Is Parkinson's an autoimmune disease?

The cause of neuronal death in Parkinson's disease is still unknown, but a new study proposes that neurons may be mistaken for foreign invaders and killed by the person's own immune system, similar to the way autoimmune diseases ...

Natural plant compound prevents Alzheimer's disease in mice

(Medical Xpress)—A chemical that's found in fruits and vegetables from strawberries to cucumbers appears to stop memory loss that accompanies Alzheimer's disease in mice, scientists at the Salk Institute for Biological ...

Addiction

Seeking new methods to treat heroin addiction

"Heroin itself is an inactive substance," explains Jørg Mørland, Norwegian forensic medicine and toxicology researcher. "The substances that heroin forms in the body are mainly what enter the brain and cause the narcotic ...

Genetics

Scientists identify ALS disease mechanism

Researchers have tied mutations in a gene that causes amyotrophic lateral sclerosis (ALS) and other neurodegenerative disorders to the toxic buildup of certain proteins and related molecules in cells, including neurons. The ...
