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.

Gulf War veterans display abnormal brain response to specific chemicals

A new study by UT Southwestern Medical Center researchers is the first to pinpoint damage inside the brains of veterans suffering from Gulf War syndrome - a finding that links the illness to chemical exposures and may lead to diagnostic tests and treatments.

Shrinking in hippocampus area of brain precedes Alzheimer's disease

People who have lost brain cells in the hippocampus area of the brain are more likely to develop dementia, according to a study published in the March 17, 2009, print issue of Neurology, the medical journal of the American Academy of Neurology.

Cause of severe pediatric epilepsy disorder discovered

Researchers at the University of California, San Diego School of Medicine have discovered that convulsive seizures in a form of severe epilepsy are generated, not on the brain's surface as expected, but from within the memory-forming hippocampus.

Does stress damage the brain?

In the March 1st issue of Biological Psychiatry, published by Elsevier, a paper by Tibor Hajszan and colleagues provides an important new chapter to this question.

Researchers show how the hippocampus records memory

It may be possible to "read" a person's memories just by looking at brain activity, according to research carried out by Wellcome Trust scientists.

Stages of sleep have distinct influence on process of learning and memory

Research on the sleeping brain has revealed some fascinating stage-dependent interactions between areas involved in formation and storage of long term memories.

Researchers find evidence for precise communication across brain areas during sleep

By listening in on the chatter between neurons in various parts of the brain, researchers from the California Institute of Technology (Caltech) have taken steps toward fully understanding just how memories are formed, transferred, and ultimately stored in the brain--and how that process varies throughout the various stages of sleep.

New insights into addiction

A new comprehensive review by researchers at the Montreal Neurological Institute (MNI), McGill University and the University of Cambridge, England provides vital insights into the neurological basis of addiction by investigating Parkinson's disease patients, who in some instances develop various addictions when undergoing medical treatment.

Protein found linking stress and depression

Stress, the ever-present threat to health and happy living, is tough on the brain. If the strain goes on too long, it can lead to debilitating psychological problems.

Physical fitness improves spatial memory, increases size of hippocampi

When it comes to the hippocampus, a brain structure vital to certain types of memory, size matters.

Researchers develop 'wireless' activation of brain circuits

Traditionally, stimulating nerves or brain tissue involves cumbersome wiring and a sharp metal electrode.

Brain-derived neurotrophic factor protects key brain cells in Alzheimer's models

Memory loss, cognitive impairment, brain cell degeneration and cell death were prevented or reversed in several animal models after treatment with a naturally occurring protein called brain-derived neurotrophic factor (BDNF).

Fasudil could reduce risk of Alzheimer's

A drug used to improve blood flow to the brain also could help improve learning and memory and reduce the risk of Alzheimer's disease, according to a new study released today by investigators at the Translational Genomics Research Institute (TGen) and Arizona State University.

Insulin may slow or prevent damage caused by toxic proteins in Alzheimer's disease

A Northwestern University-led research team reports that insulin, by shielding memory-forming synapses from harm, may slow or prevent the damage and memory loss caused by toxic proteins in Alzheimer's disease.

The end of sex as we once knew it

Women are not from Venus any more than men are from Mars. But even though both sexes are perfectly terrestrial beings, they are not lacking in other differences. And not only in their reproductive organs and behavior, either, but in such unsexy characteristics as the propensity for drug abuse, fine motor control, reaction to stress, moods and many brain structures.

New insights into growth factor's role in brain development

New research sheds light on a neural growth factor called proBDNF, finding that it is present and potentially active during the perinatal period when the brain's circuitry and memory-encoding regions are being refined.
