...concerning one type of signal transduction between nerve cells, referred to as slow synaptic transmission," according to the award citation. The Nobel Assembly at Karolinska Institute said that these discoveries had been crucial for an understanding of the normal function of the brain and have resulted in...

Evidence Links Protein Damage to Neurodegenerative diseases like Parkinson's and Alzheimer's

...dence links oxidative damage in a protein found in nerve cells to the development of degenerative diseases of the nervous system, such as Parkinson's and Alzheimer's disease. The first study to provide this evidence, conducted by University of Pennsylvania researchers, was published in the November 3, 20...

Vaccine for Alzheimer’s diseas

...the brains of Alzheimer’s patients and killing the nerve cells. When Alzheimer’s mice are vaccinated with beta-amyloid peptide they develop antibodies against the protein, which sweep the brain clean of the plagues. Mice given the test vaccine developed fewer protein deposits in their brains compared w...

Nasal Spray Could Take Drugs Direct to Brain.

...ple, the olfactory system--the sense of smell--has nerve endings “that reach down to the nose.” The drug travels along those pathways directly to the brain, he said. This method, according to Frey, means the drug reaches the brain much faster than it would if it were administered into a vein. In this stud...

...hat it is the lack of a signalling molecule called nerve growth// factor (NGF) which underlies this neuronal loss. In mice with experimental forms of these diseases, transport of NGF to these areas was impaired as the mice aged. What's more, infusing NGF into areas close to the vulnerable cells reversed ...

'Sweaty palms syndrome' can be cured by surgery

...ion and moved along the chest until it reaches the nerve associated with excessive sweating. The probe is also fitted with a cutter that is used to sever the nerve, thus stopping the signal from the brain to the hands. Since the nerves to the feet take a different route, the feet often continue to sweat a...

Drug abuse leads to long standing changes in the brain

... dopamine transporters (DAT) marks the presence of nerve cells that are part of a brain circuit that transmits signals using the chemical dopamine, which plays a role in movement control and feelings of pleasure. The researchers administered a battery of tests to assess attention, memory, mood, general int...

For a Better Memory

...n. // The corpus callosum is the large bundle of nerve fibers that connects the two sides of our brain and is one of the last major brain structures to mature. A larger corpus callosum allows for more and better communication between both halves of the brain. Memory is divided into two categories. The ...
