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.

Regular exercise could help prevent brain damage linked with Alzheimer's

Regular exercise could help prevent brain damage associated with neurodegenerative diseases like Alzheimer's, according to research published this month in Elsevier's journal Brain, Behavior, and Immunity.

Episodic memory depends on the hippocampus

Memory is not a single process but is made up of several sub-processes relying on different areas of the brain. Episodic memory, the ability to remember specific events such as what you did yesterday, is known to be vulnerable to brain damage involving the hippocampus. The question is, what happens when damage to the hippocampus occurs very early in life?

Researchers helps explain how the adult brain cleans out dead brain cells and produces new ones

Adult brains generate thousands of new brain cells called neurons each day; however only a small fraction of them survive. The rest die and are consumed by scavenger cells called phagocytes. Until now, scientists have not fully understood how this process works, which phagocytes are unique in the brain, and how the removal of dead neurons influences the production of new neurons.

Moderate exercise may help prevent cognitive decline after bacterial infection

A small amount of exercise shields older animals from memory loss following a bacterial infection, according to a study in the August 10 issue of The Journal of Neuroscience.

Anisotropic encoding of three-dimensional space by place and grid cells

Animal's brains are only roughly aware of how high-up they are in space, meaning that in terms of altitude the brain's 'map' of space is surprisingly flat, according to new research.

Scientists identify reasons behind why we are unable to recognise faces

The research, led by Dr Clea Warburton and Dr Gareth Barker in the University's School of Physiology and Pharmacology and published in the Journal of Neuroscience, has investigated why we can recognise faces much better if we have extra clues as to where or indeed when we encountered them in the first place.

UH undergraduates seek solutions to many maladies like diabetes, Alzheimer's

Students from a variety of majors are devoting their summers to serious research at the University of Houston (UH), seeking eventual solutions to many serious maladies that include Alzheimer's, high blood pressure and cholesterol, diabetes, alcoholism and anxiety.

Prolonged estrogen deprivation reduces ability to prevent strokes

Prolonged estrogen deprivation in aging rats dramatically reduces the number of brain receptors for the hormone as well as its ability to prevent strokes, researchers report.

Study: Subjective memory deterioration could be the first manifestation of Alzheimer's

Scientists at Charité - Universitätsmedizin Berlin, Universitätsklinikum Bonn, and Deutsches Zentrum für Neurodegenerative Erkrankungen in Bonn succeeded for the first time in demonstrating that even in merely subjective cases of memory deterioration changes may be visible in certain brain structures.

Insight into how brain organizes during development

Scientists at the Allen Institute for Brain Science have taken an important step in identifying how the brain organizes itself during development. The findings, published in the Journal of Comparative Neurology today, describe - in more detail than ever before - the consequences of the loss of a key molecule involved in establishing proper brain architecture during brain development.

Smoking, high blood pressure and diabetes in middle age linked to brain damage

A new study suggests smoking, high blood pressure, diabetes and being overweight in middle age may cause brain shrinkage and lead to cognitive problems up to a decade later.

Research: 7 Tesla MRI can accurately detect brain scarring linked with epilepsy

Using state-of-the-art, 7 Tesla magnetic resonance imaging (MRI) technology, University of Minnesota Medical School researchers may have uncovered a better approach to diagnosing epilepsy.

Scientists receive funding to continue research into pathological processes supporting Alzheimer's

Neuroscientists at the University of Bristol have received a major funding boost of -550,000 from the Medical Research Council to continue their research into the pathological processes underpinning Alzheimer's disease, the most common cause of dementia, affecting around 465,000 people in the UK.

New research shows unique nature of human brain aging

Brains shrink in humans, potentially causing a number of health problems and mental illnesses as people age, but do they shrink to the same extent in the closest living relatives to humans--the chimpanzees? New research says no, making the extreme amount of brain shrinkage resulting from normal aging in humans unique.

Abbott announces research confirming presence of lutein in key regions of the infant brain

Preliminary new research demonstrates for the first time that lutein, an important phytonutrient (plant-based nutrient) that supports eye health, is the predominant carotenoid present in key areas of the infant brain, including areas that regulate overall brain function, cognition, vision, hearing and speech. This new research, supported by Abbott, was presented by Elizabeth Johnson, PhD, a scientist in the Carotenoids and Health Laboratory at Tufts University, at the 16th International Symposium on Carotenoids, in Krakow, Poland.

Myelin regulates key protein involved in sending long-distance signals

The development of a new cell-culture system that mimics how specific nerve cell fibers in the brain become coated with protective myelin opens up new avenues of research about multiple sclerosis. Initial findings suggest that myelin regulates a key protein involved in sending long-distance signals.

Excess brain activity in aMCI patients contributes to brain dysfunction underlying memory loss

An existing anti-seizure drug improves memory and brain function in adults with a form of cognitive impairment that often leads to full-blown Alzheimer's disease, a Johns Hopkins University study has found.

Latest advances in Alzheimer's research presented at AAIC 2011

This week, more than 5,000 scientists from around the world gathered in Paris to report the latest advances in Alzheimer's research at the Alzheimer's Association International Conference 2011.

People with small hippocampus do not face higher risk of depression

Imaging studies have repeatedly found that people with depression have smaller hippocampal volumes than healthy individuals. The hippocampus is a brain region involved in learning and memory, spatial navigation, and the evaluation of complex life situations or "contexts".

Global research initiatives to standardize Alzheimer's biomarkers

As the Alzheimer's field moves closer to new and earlier tests for the disease, innovative global research initiatives are taking the first important steps to standardize Alzheimer's biomarkers, as evidenced by two presentations made today at the Alzheimer's Association(R) International Conference 2011 (AAIC 2011) in Paris.
