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.

Increased brain activity predicts anxious temperament in young primates

A new study focused on anxiety and brain activity pinpoints the brain regions that are relevant to developing childhood anxiety. The findings, published in the Aug. 12 edition of the journal Nature, may lead to new strategies for early detection and treatment of at-risk children.

Researchers identify perforant path brain passage associated with Alzheimer's disease

With the help of volunteers aged 18 to 89, UC Irvine researchers have identified for the first time in humans a long-hidden part of the brain called the perforant path. Scientists have struggled for decades to locate the tiny passage, which is believed to deteriorate gradually as part of normal aging and far more quickly due to Alzheimer's disease.

Scientists identify chemical system effective in cocaine-addiction cure

UT Southwestern Medical Center researchers have identified a chemical system in the brain that reacts differently in cocaine addicts, findings that could result in new treatment options for individuals addicted to the drug."We found that the amount of blood flow in areas of the brain known to be involved in the rewarding effects of cocaine and craving was different in cocaine addicts, compared with healthy subjects," said Dr. Bryon Adinoff, professor of psychiatry at UT Southwestern and lead author of a study that appeared in Neuropsychopharmacology. "Now we have a new target for pharmacologic intervention."

Study finds 'grid cells' that help brain map locations outside hippocampus

"Grid cells," which help the brain map locations, have been found for the first time outside of the hippocampus in the rat brain, according to new research from the Norwegian University of Science and Technology (NTNU). The finding should help further our understanding of how the brain generates the internal maps that help us remember where we have been and how to get to where we want to go.

University of Pennsylvania announces recipients of 2010 Templeton Positive Neuroscience Awards

The Positive Psychology Center of the University of Pennsylvania and the John Templeton Foundation have announced the recipients of the 2010 Templeton Positive Neuroscience Awards, $2.9 million given to 15 new research projects at the intersection of neuroscience and positive psychology.

Other brain regions compensates loss of amygdale: Research

Many neuroscientists believe the loss of the brain region known as the amygdala would result in the brain's inability to form new memories with emotional content. New UCLA research indicates this is not so and suggests that when one brain region is damaged, other regions can compensate.

Tel Aviv University discovers molecular power behind memory

Neuroscientists have long wondered how individual connections between brain cells remain diverse and "fit" enough for storing new memories. Reported in the prestigious science journal Neuron, a new study led by Dr. Inna Slutsky of the Sackler School of Medicine at Tel Aviv University describes what makes some memories stick.

VA approves $2.8M for Gulf War Veterans' illness research program

The Department of Veterans Affairs (VA) has approved $2.8 million to fund three new research projects that focus on testing or developing new treatments for illnesses affecting Veterans who served in the Gulf War 1990-1991. The research incorporates recommendations of the department's Gulf War Veterans' Illnesses Task Force.

Penn researchers reverse cognitive decline in fruit flies with Alzheimer's gene mutation

Investigators have found that fruit fly (Drosophila melanogaster) males -- in which the activity of an Alzheimer's disease protein is reduced by 50 percent -- show impairments in learning and memory as they age. What's more, the researchers were able to prevent the age-related deficits by treating the flies with drugs such as lithium, or by genetic manipulations that reduced nerve-cell signaling.

New research studies presented at Alzheimer's Association International Conference

The primary therapeutic target in Alzheimer's disease has been the beta amyloid peptide, which clusters outside cells in the brain to form sticky clumps known as plaques. Recently, more attention has been given to the tau protein, which aggregates inside the brain cells of people with Alzheimer's, forming neurofibrillary tangles. Precisely how these proteins interact in causing the disease is unclear.

Hormone leptin reduces food intake by activating hippocampus: Research

Research to be presented at the Annual Meeting of the Society for the Study of Ingestive Behavior, the foremost society for research into all aspects of eating and drinking behavior, finds that the hormone leptin reduces food intake, in part, by activating the hippocampus, an area of the brain that controls learning and memory function. Leptin is a hormone released from fat cells that acts on the brain to inhibit feeding.

Exercise can reverse effects of early-life trauma

Athletes have long known about the natural “high” exercise can induce. Now, for the first time, medical researchers have demonstrated that exercise can reverse the effects in the brain of psychological trauma experienced early in life.

Adeona completes $1 million equity financing and provides update on Zinthionein ZC clinical study

Adeona Pharmaceuticals, Inc., announced today that on July 6, 2010, it completed an equity financing of $1 million with a single institutional investor, Seaside 88, L.P. The financing involved the sale of 1,212,121 registered shares of common stock and no warrants. Enclave Capital served as placement agent and will receive a 7% cash commission and 5-year warrants to acquire 60,606 shares of Adeona at $1.32 per share. The use of proceeds is intended for general corporate purposes.

Research may provide key to understanding interplay between exercise, aging and neurogenesis

Stem cells in the brain remain dormant until called upon to divide and make more neurons. However, little has been known about the molecular guards that keep them quiet.

Imbalance in neuroendocrine system linked to depression in MS patients: Study

Now, in the first such study in living humans, researchers at UCLA suggest a cause, and it's not psychological, but physical: atrophy of a specific region of the hippocampus, a critical part of the brain involved in mood and memory, among other functions.

New research identifies memory and brain scan as best tests for predicting Alzheimer's disease

New research has identified the memory and brain scan tests that appear to predict best whether a person with cognitive problems might develop Alzheimer's disease. The research is published in the June 30, 2010, online issue of Neurology, the medical journal of the American Academy of Neurology.

Sleep enhances ability to remember to do something in future

When it comes to executing items on tomorrow's to-do list, it's best to think it over, then "sleep on it," say psychologists at Washington University in St. Louis.

Research findings open new ways to enhance memory function and treat catastrophic brain diseases

For the first time, scientists have linked a brain compound called kynurenic acid to cognition, possibly opening doors for new ways to enhance memory function and treat catastrophic brain diseases, according to a new study from the University of Maryland School of Medicine. When researchers decreased the levels of kynurenic acid in the brains of mice, their cognition was shown to improve markedly, according to the study, which was published in the July issue of the journal Neuropsychopharmacology.

Researchers use neonatal piglet model to study infant brain development

Events occurring during the development of an infant's brain can leave behind fingerprints. And researchers at the University of Illinois are interested in learning how these fingerprints can predict future behavioral problems such as cognitive deficits, anxiety disorders, depression, and even autism.
