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.

Exercise and increased physical activity are effective for prevention, treatment of depression

Exercise training and increased physical activity are effective for both prevention and treatment of depression, concludes a research review in the August issue of Current Sports Medicine Reports, official journal of the American College of Sports Medicine.

Depression symptoms together with AD pathology could trigger changes in memory and thinking

Increasingly, Alzheimer's disease research has focused on the preclinical stage, when people have biological evidence of AD but no or minimal symptoms, and when interventions might have the potential to prevent future decline of older adults.

Research offers new clues into why cognitive functions become impaired with age

Research at the University of Leicester is offering new clues into how and why cognitive functions such as memory and learning become impaired with age. A paper published recently in a specialist neuroscience journal shows that a crucial factor is calcium levels in specific cells in the brain.

Researchers investigate how deep space travel could affect the brain

Exposure to chronic, low dose radiation — the conditions present in deep space — causes neural and behavioral impairments in mice, researchers report in eNeuro.

Johns Hopkins researchers link 'stressors' in middle age to memory decline in older women

A new analysis of data on more than 900 Baltimore adults by Johns Hopkins Medicine researchers has linked stressful life experiences among middle-aged women -- but not men -- to greater memory decline in later life.

Astrocytic MORs in the hippocampus responsible for conditioned place preference

If somebody asks me "are you a coffee addict?" I may say, "Yeah it seems like, but on the one condition, only in my office." I don't have that much craving for coffee at home, but just being in the office, where I used to drink coffee all the time seeking to get caffeine jitters, seems to trigger my caffeine-addicted brain.

Study discovers paradoxical proinflammatory effect of endocannabinoids in the brain

A new study led by the Neuropharmacology Laboratory -NeuroPhar at UPF shows that increasing endocannabinoids in the brain may cause inflammation in specific brain areas such as the cerebellum, which is associated with problems of fine motor coordination.

Discovery could open door to new therapies for Parkinson's, other brain diseases

A small protein previously associated with cell dysfunction and death in fact serves a critical function in repairing breaks in DNA, according to new research led by scientists at Oregon Health & Science University.

Resveratrol shows promise for anxiety and depression

A new study has shown that the compound resveratrol found in red wine demonstrates stress relieving effects in anxiety and depression. This could be due to resveratrol’s ability to control an enzyme in the brain that is liked to stress say the researchers from the University at Buffalo in collaboration with Xuzhou Medical University in China.

Exosomes can restore health to brain cells affected by developmental disease

Like overpacked suitcases unloaded from the underbelly of a jet, molecular satchels called exosomes are continuously deployed from all cells in the body—each one brimming with an assortment of contents that another cell may unpack and use.

Researchers report how a popular antidepressant drug could rewire the brain

Prozac, the trade name for the drug fluoxetine, was introduced to the U.S. market for the treatment of depression in 1988.

Age-related risk of Alzheimer's explained at the molecular level

Studies have shown that Alzheimer’s disease (AD) incidence increases with age. This association with age also correlates with deposits of abnormal tau protein in the brain found a new study.

A non-coding RNA may play major role in memory formation

You could call this a neat discovery. Researchers at the University of Alabama at Birmingham have found that a tissue-specific, non-coding RNA called NEAT1 has a major, previously undescribed role in memory formation.

Sleep decline in one's 50s, 60s increases risk of Alzheimer's disease

People who report a declining quality of sleep as they age from their 50s to their 60s have more protein tangles in their brain, putting them at higher risk of developing Alzheimer's disease later in life, according to a new study by psychologists at the University of California, Berkeley.
