Researchers shed new light on genetics of Parkinson's

A new study by Narendra et al. suggests that Parkin, the product of the Parkinson's disease-related gene Park2, prompts neuronal survival by clearing the cell of its damaged mitochondria.

Neurons in adult brain can remodel their connections

In work reported in the Nov. 24 online edition of the Proceedings of the National Academy of Sciences (PNAS) , Elly Nedivi, associate professor of neurobiology at the Picower Institute for Learning and Memory, and colleagues found that a type of neuron implicated in autism spectrum disorders remodels itself in a strip of brain tissue only as thick as four sheets of tissue paper at the upper border of cortical layer 2.

Researchers discover mechanism vital to the development of the hippocampus

Astrophysicists peer into the far corners of deep space for dark matter, but for neuroscientists at the Queensland Brain Institute (QBI) exploring the unknown is much closer to home.

Marijuana may be good for the aging brain

The more research they do, the more evidence Ohio State University scientists find that specific elements of marijuana can be good for the aging brain by reducing inflammation there and possibly even stimulating the formation of new brain cells.

Researchers identify best time for stem cell collection for Parkinson's therapy

Researchers have identified a stage during dopamine neuron differentiation that may be an ideal time to collect human embryonic stem cells for transplantation to treat Parkinson's disease, according to data presented at Neuroscience 2008, the 38th annual meeting of the Society for Neuroscience.

Researchers use embryonic stem cells from mice to grow motor neurons

Dalhousie Medical School researchers have discovered that embryonic stem cells may play a critical role in helping people with nerve damage and motor neuron diseases, such as amyotrophic lateral sclerosis (ALS), regain muscular strength.

Computational model provides insight into function of brain's visual cortex

Computational neuroscientists at Carnegie Mellon University have developed a computational model that provides insight into the function of the brain's visual cortex and the information processing that enables people to perceive contours and surfaces, and understand what they see in the world around them.

High levels of social support may protect brain during stroke

New research in mice suggests that high levels of social support may provide some protection against strokes by reducing the amount of damaging inflammation in the brain.

Maas Biolab scientists validate cyclosporin human neuroprotection

Maas Biolab researchers CSO Eskil Elmer, M.D., Ph.D. and neuroscientist Magnus Hansson, M.D., Ph.D., and colleagues have for the first time ever demonstrated the mitochondrial permeability transition (mPT) or "megapore" occurs in viable adult human neuron mitochondria and the ability of cyclosporin-A to block its formation.

A link found between nicotine addiction and autism

Scientists have identified a relationship between two proteins in the brain that has links to both nicotine addiction and autism.

New evidence on how proteins help cells fix broken DNA

Aucott et al. report the first in vivo experiments on the heterochromatin protein 1 (HP1) family, which sidles up to silent DNA.

New research reveals key steps in HIV's assault on the brain

Scientists have unraveled in unprecedented detail the cascade of events that go wrong in brain cells affected by HIV, a virus whose assault on the nervous system continues unabated despite antiviral medications that can keep the virus at bay for years in the rest of the body.

New clue for cellular damage in Huntington's disease

"Huntington's disease presents an ideal vantage point to study neurodegenerative disease, because we know the misfolded protein that's responsible," says Martin Duennwald, formerly a postdoctoral researcher in the lab of Whitehead Member Susan Lindquist.

Breakthrough in cell-type analysis offers new ways to study development and disease

Like skilled assassins, many diseases seem to know exactly what types of cells to attack. While decimating one cadre of cells, diseases will inexplicably spare a seemingly identical group of neighbors. What makes cells vulnerable or not depends largely on the kinds and amounts of proteins they produce - their 'translational profile,' in the lingo of molecular biology. For this reason, scientists have struggled to parse the subtle molecular differences among the hundreds of specialized cell types that are tangled together in tissues like the brain.
