Hippocampus News and Research RSS Feed - Hippocampus News and Research

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.

Scientists investigate role of mitochondria in Alzheimer's disease pathology

On Nov. 25, 1901, a 51-year-old woman is admitted to a hospital in Frankfurt, Germany, displaying a bizarre constellation of symptoms. [More]
Lack of shrinkage in the hippocampus may help predict people at risk for dementia with Lewy bodies

Lack of shrinkage in the hippocampus may help predict people at risk for dementia with Lewy bodies

Dementia with Lewy bodies is a progressive disease that causes hallucinations, decline in mental abilities, rigid muscles, slow movement and tremors. With symptoms similar to Alzheimer's disease and Parkinson's disease, a correct diagnosis can be difficult. [More]
Lack of brain shrinkage may help identify people at risk for dementia with Lewy bodies

Lack of brain shrinkage may help identify people at risk for dementia with Lewy bodies

A lack of shrinkage in the area of the brain responsible for memory may be a sign that people with thinking and memory problems may go on to develop dementia with Lewy bodies rather than Alzheimer's disease, according to a new study published in the November 2, 2016, online issue of Neurology, a medical journal of the American Academy of Neurology.

Research findings offer detailed insight into mechanics of learning

Research findings offer detailed insight into mechanics of learning

Scientists at The University of Texas at Austin can now map what happens neurologically when new information influences a person to change his or her mind, a finding that offers more insight into the mechanics of learning. [More]
Researchers explore interaction between two brain regions during formation of long-term memories

Researchers explore interaction between two brain regions during formation of long-term memories

Our brain has a tough task every time we experience something new - it must be flexible to take in new information instantly, but also stable enough to store it for a long time. [More]
Ionizing radiation may be confounding factor in Alzheimer's disease, study suggests

Ionizing radiation may be confounding factor in Alzheimer's disease, study suggests

More humans than ever are exposed to higher levels of ionizing radiation from medical equipment, airplanes, etc. A new study suggests that this kind of radiation may be a confounding factor in the neurodegenerative disease Alzheimer´s. [More]

Vanderbilt scientists develop new bioluminescent sensor that can light up brain cells in the dark

A new kind of bioluminescent sensor causes individual brain cells to imitate fireflies and glow in the dark. [More]
Scientists identify commonly affected genes sets among people with three mental disorders

Scientists identify commonly affected genes sets among people with three mental disorders

Studying brain tissue from deceased donors, Johns Hopkins scientists have found common groups of genes disrupted among people with schizophrenia, bipolar disorder and major depression. [More]
Novel approach to analyzing brain structures may help predict progression of Alzheimer's disease

Novel approach to analyzing brain structures may help predict progression of Alzheimer's disease

Use of a novel approach to analyzing brain structure that focuses on the shape rather than the size of particular features may allow identification of individuals in early presymptomatic stages of Alzheimer's disease. [More]
Adult brain cells may be vulnerable to Zika infection, new study suggests

Adult brain cells may be vulnerable to Zika infection, new study suggests

Concerns over the Zika virus have focused on pregnant women due to mounting evidence that it causes brain abnormalities in developing fetuses. However, new research in mice from scientists at The Rockefeller University and La Jolla Institute for Allergy and Immunology suggests that certain adult brain cells may be vulnerable to infection as well.

Study unravels how caloric restriction provides beneficial effects to the brain

Study unravels how caloric restriction provides beneficial effects to the brain

Studies of different animal species suggest a link between eating less and living longer, but the molecular mechanisms by which caloric restriction affords protection against disease and extends longevity are not well understood. [More]
New study unravels cause of cognitive loss in tauopathy disorders

New study unravels cause of cognitive loss in tauopathy disorders

Tauopathies are a group of neurodegenerative disorders, including Alzheimer's disease that are characterized by the deposition of aggregates of the tau protein inside brain cells. [More]
Brain atrophy patterns linked to loss of specific cognitive abilities in patients with Alzheimer's disease

Brain atrophy patterns linked to loss of specific cognitive abilities in patients with Alzheimer's disease

Mathematical modeling of the brain scans of patients with Alzheimer's disease and others at risk for the devastating neurodegenerative disorder has identified specific patterns of brain atrophy that appear to be related to the loss of particular cognitive abilities. [More]
People with PTSD appear to suffer from disrupted context processing, say researchers

People with PTSD appear to suffer from disrupted context processing, say researchers

For decades, neuroscientists and physicians have tried to get to the bottom of the age-old mystery of post-traumatic stress disorder, to explain why only some people are vulnerable and why they experience so many symptoms and so much disability. [More]
Psychologist designs interactive game for testing memory

Psychologist designs interactive game for testing memory

Psychologist Jamie Edgin studies human memory at the University of Arizona, where her research often involves working with very young children and children with intellectual disabilities. [More]
Scientists identify new pathway in the brain that can be targeted to alleviate depression

Scientists identify new pathway in the brain that can be targeted to alleviate depression

Northwestern Medicine scientists have discovered a new pathway in the brain that can be manipulated to alleviate depression. The pathway offers a promising new target for developing a drug that could be effective in individuals for whom other antidepressants have failed. [More]
