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.

Further support for hippocampal volume as psychosis biomarker

Findings from the Bipolar-Schizophrenia Network on Intermediate Phenotypes provide further evidence that reduced hippocampal volume is a consistent feature of schizophrenia. [More]

Electrical stimulation of hippocampus activates dormant memory cells

The electrical stimulation of the hippocampus in in-vivo experiments activates precisely the same receptor complexes as learning or memory recall. This has been discovered for the first time and the finding has now been published in the highly respected journal "Brain Structure Function". [More]
CUMC researchers find potential target for treating autism, schizophrenia, and other brain disorders

CUMC researchers find potential target for treating autism, schizophrenia, and other brain disorders

​Columbia University Medical Center (CUMC) researchers have determined that a small region of the hippocampus known as CA2 is essential for social memory, the ability of an animal to recognize another of the same species. [More]

Neuropsychological assessment efficiently tracks disease progression in memory clinic patients

Investigators at the University of Amsterdam, The Netherlands, have shown that progression of disease in memory clinic patients can be tracked efficiently with 45 minutes of neuropsychological testing. MRI measures of brain atrophy were shown to be less reliable to pick up changes in the same patients. [More]
New treatments for depression on the horizon

New treatments for depression on the horizon

New insights into the physiological causes of depression are leading to treatments beyond common antidepressants such as Prozac and Zoloft, researchers are reporting in the in the journal Current Psychiatry. [More]
Chronic stress generates long-term changes in brain that lead to mental problems

Chronic stress generates long-term changes in brain that lead to mental problems

University of California, Berkeley, researchers have shown that chronic stress generates long-term changes in the brain that may explain why people suffering chronic stress are prone to mental problems such as anxiety and mood disorders later in life. [More]
Researchers investigate sex differences in brain structure

Researchers investigate sex differences in brain structure

Reviewing over 20 years of neuroscience research into sex differences in brain structure, a Cambridge University team has conducted the first meta-analysis of the evidence, published this week in the prestigious journal Neuroscience and Biobehavioral Reviews. [More]
Being overweight may cause changes in brain that is crucial to appetite, emotions and memory

Being overweight may cause changes in brain that is crucial to appetite, emotions and memory

Being overweight appears related to reduced levels of a molecule that reflects brain cell health in the hippocampus, a part of the brain involved in memory, learning, and emotions, and likely also involved in appetite control, according to a study performed by researchers at SUNY Downstate Medical Center and other institutions.

Some neurologic diseases associated with prenatal exposure to inflammatory immune responses

Some neurologic diseases associated with prenatal exposure to inflammatory immune responses

Johns Hopkins researchers report that fetal mice — especially males — show signs of brain damage that lasts into their adulthood when they are exposed in the womb to a maternal immune system kicked into high gear by a serious infection or other malady. The findings suggest that some neurologic diseases in humans could be similarly rooted in prenatal exposure to inflammatory immune responses. [More]
Research suggests that male mice may be vulnerable to effects of maternal inflammation than females

Research suggests that male mice may be vulnerable to effects of maternal inflammation than females

Johns Hopkins researchers report that fetal mice - especially males - show signs of brain damage that lasts into their adulthood when they are exposed in the womb to a maternal immune system kicked into high gear by a serious infection or other malady. [More]
New technique helps identify shrinkage of mood-regulating brain structure in women with MS

New technique helps identify shrinkage of mood-regulating brain structure in women with MS

A multicenter research team led by Cedars-Sinai neurologist Nancy Sicotte, MD, an expert in multiple sclerosis and state-of-the-art imaging techniques, used a new, automated technique to identify shrinkage of a mood-regulating brain structure in a large sample of women with MS who also have a certain type of depression.

3-D model of famous amnesiac's brain helps illuminate human memory

During his lifetime, Henry G. Molaison (H.M.) was the best-known and possibly the most-studied patient of modern neuroscience. Now, thanks to the postmortem study of his brain, based on histological sectioning and digital three-dimensional construction led by Jacopo Annese, PhD, at the University of California, San Diego, scientists around the globe will finally have insight into the neurological basis of the case that defined modern studies of human memory.

Researchers suggest possible novel target for seizure-blocking medicines

Researchers suggest possible novel target for seizure-blocking medicines

Researchers in the biomedical engineering department at Case Western Reserve University have found that epileptic activity can spread through a part of the brain in a new way, suggesting a possible novel target for seizure-blocking medicines. [More]
Early onset of dietary treatment may slow down progression of Alzheimer's disease

Early onset of dietary treatment may slow down progression of Alzheimer's disease

New research findings indicate that an early onset of dietary treatment may slow down the progression of Alzheimer's disease. The study was conducted on mice, and the results will be published in the February issue of Journal of Nutritional Biochemistry. Researchers from the University of Eastern Finland played a key role in the study, which was carried out as part of the LiPiDiDiet project funded by the European Union. [More]

Neuroscientists reveal how brain determines timing at which neurons take to create new memories

​Neuroscientists from the University of Leicester, in collaboration with the Department of Neurosurgery at the University California Los Angeles (UCLA), are to reveal details of how the brain determines the timing at which neurons in specific areas fire to create new memories. [More]
People with higher levels of omega-3 fatty acids may have larger brain volumes in old age

People with higher levels of omega-3 fatty acids may have larger brain volumes in old age

People with higher levels of the omega-3 fatty acids found in fish oil may also have larger brain volumes in old age equivalent to preserving one to two years of brain health, according to a study published in the January 22, 2014, online issue of Neurology, the medical journal of the American Academy of Neurology. Shrinking brain volume is a sign of Alzheimer's disease as well as normal aging. [More]
Researchers demonstrate existence of an epigenetic lesion in hippocampus of Alzheimer patients

Researchers demonstrate existence of an epigenetic lesion in hippocampus of Alzheimer patients

Alzheimer's disease can reach epidemic range in the coming decades, by the increasing average age of society. There are two key issues for Alzheimer's disease: there is currently no effective treatment and it has been described very few associated genetic changes (mutations) which reduces the number of targets for future therapies.
