Hippocampus News and Research

RSS

The hippocampus is a part of the forebrain, located in the medial temporal lobe. It belongs to the limbic system and plays major roles in short term memory and spatial navigation. Humans and other mammals have two hippocampi, one in each side of the brain.

Higher leptin levels associated with lower incidence of AD and dementia

Persons with higher levels of leptin, a protein hormone produced by fat cells and involved in the regulation of appetite, may have an associated reduced incidence of Alzheimer disease and dementia, according to a study in the December 16 issue of JAMA.

Varian Medical Systems introduces RapidArc radiotherapy technology in Finland

Cancer patients in Finland have gained access to more advanced treatments with the introduction of RapidArc® radiotherapy technology from Varian Medical Systems at the only private radiotherapy clinic in the Nordic region.

Researchers discover enzyme activity behind sleep deprivation

There is hope for those who miss one night too many or whose children keep them up at night. The unwelcome effects of a bad night's sleep - forgetfulness, impaired mental performance - can be dealt with by reducing the concentration of an enzyme in the brain. These are the conclusions of research published by Rubicon-grant winner Robbert Havekes and colleagues in the 22 October issue of Nature.

Cell transplants may yield new therapies for dementia patients

Nerve cells transplanted into brain-damaged rats helped them to fully recover their ability to learn and remember, probably by promoting nurturing, protective growth factors, according to a new study.

Rats exposed to passive smoking become dependent on nicotine, reveals study

Rats passively exposed to tobacco smoke become dependent on nicotine, according to a new study by Dr. Adrie Bruijnzeel and colleagues from the University of Florida in the US. Their findings of how rats' brains respond to exposure to tobacco smoke have implications for the study of the effects of tobacco smoke on the human brain even from passive exposure to other smokers, and for future studies testing new treatments for tobacco addiction. Their work has just been published online in Springer's journal Psychopharmacology.

Psychological trauma leaves a trail of damage in a child's brain, reveal scientists

Psychological trauma leaves a trail of damage in a child's brain, say scientists at the Stanford University School of Medicine and Lucile Packard Children's Hospital. Their new study gives the first direct evidence that children with symptoms of post-traumatic stress suffer poor function of the hippocampus, a brain structure that stores and retrieves memories. The research helps explain why traumatized children behave as they do and could improve treatments for these kids.

Amino acids can improve cognitive function in patients with severe brain injuries

Neurology researchers have shown that feeding amino acids to brain-injured animals restores their cognitive abilities and may set the stage for the first effective treatment for cognitive impairments suffered by people with traumatic brain injuries.

GIND scientists identify drug treatments that can normalize neuron development in AD

Scientists at the Gladstone Institute of Neurological Disease (GIND) have discovered that two main causes of AD amyloid-beta (Aβ) peptides and apolipoprotein E4 (apoE4) impair the growth of new neurons born in adult brains. What is more, they have identified drug treatments that can normalize the development of these cells even in the presence of Aβ or apoE4. The findings are described in two separate papers published in the current issue of Cell Stem Cell.

New findings shake the foundations of Alzheimer's research

Alzheimer's disease is caused by the build-up of a brain peptide called amyloid-beta. That's why eliminating the protein has been the focus of almost all drug research pursuing a cure for the devastating neurodegenerative condition.

Exposure to gas fumes can increase aggressive behavior

Outrageous prices may not be the only thing causing anger at the petrol pumps. A new study, published in the open access journal BMC Physiology, has shown that rats exposed to fumes from leaded and unleaded gasoline become more aggressive.

C3a peptide regulates the generation of new nerve cells in the brain: Study

The generation of new nerve cells in the brain is regulated by a peptide known as C3a, which directly affects the stem cells' maturation into nerve cells and is also important for the migration of new nerve cells through the brain tissue, reveals new research from the Sahlgrenska Academy published in the journal Stem Cells.

Foods rich in antioxidant substances could delay the onset of Alzheimer's disease

Universitat Autònoma de Barcelona (UAB) researchers have confirmed that a diet rich in polyphenols and polyunsaturated fatty acids, patented as an LMN diet, helps boost the production of the brain's stem cells -neurogenesis- and strengthens their differentiation in different types of neuron cells.

Brain uses a mechanism to filter out distracting thoughts to focus on single information

The human brain is bombarded with all kinds of information, from the memory of last night's delicious dinner to the instructions from your boss at your morning meeting. But how do you "tune in" to just one thought or idea and ignore all the rest of what is going on around you, until it comes time to think of something else?

Possible new approach to slow the progression of cognitive decline in Down's syndrome

A study by neuroscientist William C. Mobley, MD, PhD, chair of the Department of Neurosciences at the University of California, San Diego School of Medicine, and colleagues at Stanford University Medical School has demonstrated a possible new approach to slowing the inevitable progression of cognitive decline found in Down's syndrome.

New neuroimaging techniques yield new insights on Alzheimer's disease

Brain imaging can offer a window into risk for diseases such as Alzheimer's disease (AD). A study conducted at the University of Kansas School of Medicine demonstrated that genetic risk is expressed in the brains of even those who are healthy, but carry some risk for AD. The results of this study are published in the November 2009 issue of the Journal of Alzheimer's Disease.

Scientists develop new technique to measure brain volume loss for monitoring of Alzheimer's disease

In a study that promises to improve diagnosis and monitoring of Alzheimer's disease, scientists at the University of California, San Diego have developed a fast and accurate method for quantifying subtle, sub-regional brain volume loss using magnetic resonance imaging (MRI). The study will be published the week of November 16 in the Proceedings of the National Academy of Sciences (PNAS).

Mithridion reports progress with its potential oral small-molecule drugs for AD and schizophrenia

Mithridion, Inc., a biopharmaceutical company focusing on developing drugs for serious Central Nervous System (CNS) disorders, announced today progress with its pipeline of potential oral small-molecule drugs for Alzheimer's disease (AD) and schizophrenia.

Study: Estrogen replacement may help protect brain damage

Eighteen years ago this month the National Institutes of Health (NIH) announced that it would sponsor a landmark study to examine women and cardiovascular disease. Known as the Women's Health Initiative (WHI), the study enrolled more than 161,000 women.
