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.

MRI, EEG may predict children’s epilepsy risk after long febrile seizures

Children who have prolonged febrile seizures are at increased risk for magnetic resonance imaging observed hippocampal injury and abnormal hippocampal and temporal development, show results from the Consequences of Prolonged Febrile Seizures in Childhood study.

Early clues regarding progression of Alzheimer's disease found in brain's metabolism

When it comes to Alzheimer's disease, scientists usually - and understandably - look to the brain as their first center of attention. Now researchers at Tel Aviv University say that early clues regarding the progression of the disease can be found in the brain's metabolism.

Social or daily drinking may be more harmful to brain health

Drinking a couple of glasses of wine each day has generally been considered a good way to promote cardiovascular and brain health. But a new Rutgers University study indicates that there is a fine line between moderate and binge drinking - a risky behavior that can decrease the making of adult brain cells by as much as 40 percent.

Dartmouth neurobiologist investigates brain's nerve cells that establish one's location and direction

The Who asked "who are you?" but Dartmouth neurobiologist Jeffrey Taube asks "where are you?" and "where are you going?" Taube is not asking philosophical or theological questions. Rather, he is investigating nerve cells in the brain that function in establishing one's location and direction.

Two opposing mechanisms support voluntary forgetting of unwanted memories

If only there were a way to forget that humiliating faux pas at last night's dinner party. It turns out there's not one, but two opposite ways in which the brain allows us to voluntarily forget unwanted memories, according to a study published by Cell Press October 17 in the journal Neuron.

Neuralstem initiates second cohort NSI-189 Phase Ib trial in major depressive disorder

Neuralstem, Inc. announced that it has begun dosing the second cohort of patients in its ongoing Phase Ib to test the safety of NSI-189 in the treatment of major depressive disorder (MDD).

New findings on sleep deprivation presented at Neuroscience 2012

New findings presented today report the important role sleep plays, and the brain mechanisms at work as sleep shapes memory, learning, and behavior. The findings were presented at Neuroscience 2012, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news about brain science and health.

New radiation therapy can reduce risk of neurocognitive adverse effects in children

Children who undergo brain radiation therapy run a significant risk of suffering from permanent neurocognitive adverse effects. These adverse effects are due to the fact that the radiation often encounters healthy tissue. This reduces the formation of new cells, particularly in the hippocampus - the part of the brain involved in memory and learning.

Pregnancy stress can cut brain benefits of motherhood

A new study in animals shows that chronic stress during pregnancy prevents brain benefits of motherhood, a finding that researchers suggest could increase understanding of postpartum depression.

Perception test could predict mild cognitive impairment

Psychologists at the University of Toronto and the Georgia Institute of Technology - commonly known as Georgia Tech - have shown that an individual's inability to recognize once-familiar faces and objects may have as much to do with difficulty perceiving their distinct features as it does with the capacity to recall from memory.

New drug candidate improves cognitive function of rats with Alzheimer's-like mental impairment

Washington State University researchers have developed a new drug candidate that dramatically improves the cognitive function of rats with Alzheimer's-like mental impairment.

Study compares gene expression levels in two key hippocampal regions affected by Alzheimer's

Researchers from the Computational Intelligence Group based at the Universidad Politécnica de Madrid's Facultad de Informática have used machine learning and data mining techniques to compare gene expresssion levels in Alzheimer's disease (AD) patients in two key regions of the hippocampus: the dentate gyrus, where the disease appears to have little or no effect, and the entorhinal cortex, where Alzheimer's disease produces major neuronal damage.

Scientists discover how protein deficiency may be linked to frontotemporal dementia

Using animal models, scientists at the Gladstone Institutes have discovered how a protein deficiency may be linked to frontotemporal dementia (FTD)-a form of early-onset dementia that is similar to Alzheimer's disease. These results lay the foundation for therapies that one day may benefit those who suffer from this and related diseases that wreak havoc on the brain.

Researchers discover new group of nerve cells that regulate processes of learning and memory

Swedish researchers at Uppsala University have, together with Brazilian collaborators, discovered a new group of nerve cells that regulate processes of learning and memory. These cells act as gatekeepers and carry a receptor for nicotine, which can explain our ability to remember and sort information.

Study provides direct evidence for persistent activity in medial entorhinal cortex layer neurons

UCLA researchers have for the first time measured the activity of a brain region known to be involved in learning, memory and Alzheimer's disease during sleep. They discovered that this part of the brain behaves as if it's remembering something, even under anesthesia, a finding that counters conventional theories about memory consolidation during sleep.

Obesity from high-energy diets may impair brain, fuel overeating

"Betcha can't eat just one!" For obese people trying to lose weight, the Lays potato chip advertising slogan hits a bit too close to home as it describes the daily battle to resist high calorie foods.

Memory impairments linked to object perception among people with early stage Alzheimer's

A new study from Georgia Tech and the University of Toronto suggests that memory impairments for people diagnosed with early stage Alzheimer's disease may be due, in part, to problems in determining the differences between similar objects.

Study elucidates memory-forming signal transmission in the hippocampus

The hippocampus represents an important brain structure for learning. Scientists at the Max Planck Institute of Psychiatry in Munich discovered how it filters electrical neuronal signals through an input and output control, thus regulating learning and memory processes.

Adult stem cells can prevent Alzheimer's disease

In the first study of its kind, researchers at Korea's leading university and the RNL Bio Stem Cell Technology Institute announced this week the results of a study that suggests an astounding possibility: adult stem cells may not only have a positive effect on those suffering from Alzheimer's disease, they can prevent the disease.
